Answer 1

"Rolling a die until a 3 shows" can be modeled by a geometric distribution due to independent trials with a constant probability of success, with an expected value of 6 rolls.

What is the geometric distribution and how does it model the rolling of a die until a 3 shows?

Rolling a die until a 3 shows can be modeled by a geometric distribution because:

It involves a sequence of independent trials, where each trial has only two possible outcomes: success (rolling a 3) or failure (rolling any other number).The probability of success is constant and equal to 1/6 for each trial.The experiment continues until the first success occurs, i.e., until a 3 is rolled for the first time.

The geometric distribution models the number of trials needed to achieve the first success in a sequence of independent trials with a constant probability of success. In this case, the number of trials needed to roll a 3 for the first time can be modeled by a geometric distribution with a probability of success of 1/6.

The expected value of the geometric distribution is calculated as 1/p, where p is the probability of success. Therefore, the expected number of rolls needed to roll a 3 for the first time is 1/(1/6) = 6.

Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Answer:

y = x + 7

Step-by-step explanation:

The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept. We are given that the slope of the line is 1, so we can substitute m = 1 into the equation:

y = 1x + b

We also know that the line passes through the point (-2, 5), so we can substitute x = -2 and y = 5 into the equation and solve for b:

5 = 1(-2) + b5 = -2 + bb = 7

Therefore, the equation of the line in slope-intercept form is:

y = x + 7

This is the final answer, written in slope-intercept form using integers.

Answer:

The Equation of the Line is : y = x + 7

Step-by-step explanation:

Equation of the Line in Slope-Intercept Form is y = mx + b

where m is the Slope and b is the y-intercept

since the slope (m) = 1 , Substitute by m = 1 in the above equation

Then the Equation will be y = x + b

Since the line passes through point ( -2 , 5 ) , Then y = 5 when x = - 2

Substitute , Then 5 = -2 + b

Then b = 5 + 2 =7

So the Equation will be y = x + 7

7. Manoj and his younger sister Sandhya had their birthday yesterday i.e. Saturday, 15 th February, 2003. They were both born on Saturday. The sum of their ages is 23. Find their dates of birth. ​

Answers

Answer:

to find the date of birth from the age, you need to subtract the number of years and days from the current date. In this case, the current date is 15 February 2003. The sum of their ages is 23, which means that Manoj and Sandhya have a difference of 23 years between their dates of birth. Since they were both born on Saturday, their dates of birth must be on the same day of the month. Therefore, we can assume that Manoj was born on 15 February 1980 and Sandhya was born on 15 February 2003. This is one possible solution, but there may be other solutions depending on the leap years and calendar changes.

Answer:

The dates of birth of Manoj and Sandhya are February 15th, 1981 and February 15th, 1979 respectively.

Step-by-step explanation:

Let's use a system of equations to solve the problem.

Let M be Manoj's age and S be Sandhya's age. We know that their ages sum up to 23, so:

M + S = 23

We also know that they were both born on a Saturday, which means their birthdays fall on the same day of the week. In 2003, February 15th was a Saturday, so we can assume that they were born on February 15th in different years. Let's represent the year of Manoj's birth as M_year and the year of Sandhya's birth as S_year.

Since they were both born on a Saturday, we know that the year of Manoj's birth plus his age (M_year + M) must have the same remainder when divided by 7 as the year of Sandhya's birth plus her age (S_year + S). In other words:

(M_year + M) mod 7 = (S_year + S) mod 7

We can simplify this equation by subtracting M from both sides and then substituting 23 - S for M:

(M_year + (23 - S)) mod 7 = (S_year + S) mod 7

Now we have two equations with two unknowns. We can solve for M_year and S_year by guessing values for S and then checking if there are integers M and S_year that satisfy both equations. We know that M and S must be positive integers and that their sum is 23. Here are a few guesses:

If S = 1, then M = 22 and the equation becomes:

(M_year + 22) mod 7 = (S_year + 1) mod 7

This simplifies to:

M_year mod 7 = (S_year + 6) mod 7

There are no integers M_year and S_year that satisfy this equation, since the two sides always have different remainders when divided by 7.

If S = 2, then M = 21 and the equation becomes:

(M_year + 21) mod 7 = (S_year + 2) mod 7

This simplifies to:

M_year mod 7 = (S_year + 5) mod 7

The only pair of integers that satisfies this equation is M_year = 2 and S_year = 4.

Therefore, Manoj was born on February 15th, 1981 and Sandhya was born on February 15th, 1979.

So the dates of birth of Manoj and Sandhya are February 15th, 1981 and February 15th, 1979 respectively.

Answers

There are many tools available to calculate the line of best fit, including Excel, R, and Python. These tools provide the best equation that approximates the data

To determine which equation could be used as a line of best fit to approximate the data in a scatter plot, we need to look for the equation that closely follows the general trend of the data. The line of best fit is the straight line that best represents the data on the graph.

One common method for finding the line of best fit is through linear regression analysis. This involves calculating the slope and intercept of the line that best fits the data. The equation for a line is y = mx + b, where m is the slope and b is the y-intercept.

In general, the equation that could be used as a line of best fit depends on the data on the scatter plot. However, we can determine the best equation by looking at the trend of the data. If the data shows a positive trend, we need to choose an equation with a positive slope. If the data shows a negative trend, we need to choose an equation with a negative slope.

To determine the equation of the line of best fit for a specific scatter plot, we need to use regression analysis. and allows us to make predictions based on the data.

A number line is a visual representation of numbers, ordered from left to right, where each point on the line corresponds to a number. The number line can be used to represent a wide range of numbers, including integers, fractions, decimals, and even negative numbers.

On a basic number line, 0 is located in the center, with positive numbers to the right and negative numbers to the left. The numbers are usually evenly spaced, with tick marks or dots indicating each value. The distance between any two points on the number line represents the difference between the corresponding numbers.

According to question Option D is correct

This is because starting at 5/6 and ending at 1/6 involves moving in the negative direction on the number line. To find the distance between these two points, we need to subtract the smaller number (1/6) from the larger number (5/6).

Q3
Activity: Calculate:
a) the percentage change in the firm's variable costs (give your answer to two decimal places)
b) the new number of Crystal Clear's smallest greenhouses that would need to be sold per
month for the business to break even
our workings:

Answers

Answer:

a) the percentage change in the firm's variable costs is 66.67%.

b) Crystal Clear would need to sell 200 of its smallest greenhouses per month to break even.

Step-by-step explanation:

a) The percentage change in variable costs can be calculated using the formula:

((New Value - Old Value) / Old Value) * 100%

Substituting the values, we get:

((£100 - £60) / £60) * 100% = 66.67%

Therefore, the percentage change in the firm's variable costs is 66.67%.

b) The break-even point is the point at which the total revenue equals total costs. The total cost is the sum of fixed costs and variable costs.

Let's assume that the fixed costs for Crystal Clear are £10,000 per month. Then, the total cost can be calculated as:

Total Cost = Fixed Cost + (Variable Cost per unit * Number of units)

We can rearrange this formula to find the number of units:

Number of units = (Fixed Cost + Total Cost) / Variable Cost per unit

At the break-even point, the total revenue equals the total cost. Let's assume that the selling price per unit is £150. Then, the break-even point can be calculated as:

Total Revenue = Total Cost

Number of units * Selling Price per unit = Fixed Cost + (Variable Cost per unit * Number of units)

Number of units * £150 = £10,000 + (£100 * Number of units)

Number of units * (£150 - £100) = £10,000

Number of units = £10,000 / £50

Number of units = 200

Therefore, Crystal Clear would need to sell 200 of its smallest greenhouses per month to break even.

The Acme Company manufactures widgets. The distribution of widget weights is bell-shaped with a mean of 59 ounces and a standard deviation of 6 ounces. Using the Empirical Rule, answer the following questions. Suggestion: Sketch the distribution. a) 95% of the widget weights lie between and b) What percentage of the widget weights lie between 53 and 71 ounces? % c) What percentage of the widget weights lie above 41? %

Answers

The proportion of company breadth between the widget's weight of [tex]0.13[/tex]and its weight of [tex]71[/tex]ounce is [tex]81.53[/tex].

What does the term "company" mean?

Meaning of the word "company" A company is a collective of individuals. The word "company" is frequent and has several distinct meanings, but they are all related to gatherings or interactions of people. The most frequent usage of the term "company" is to describe a firm.

a) Using the Empirical Rule, we know that for a bell-shaped distribution, approximately [tex]68[/tex]% of the data falls within one standard deviation of the mean, [tex]95[/tex]% falls within two standard deviations of the mean, and [tex]99.7[/tex]% falls within three standard deviations of the mean. Therefore, for this problem, we can say:

[tex]95[/tex]% of the widget weights lie between [tex](59-2(6)) = 47[/tex] and [tex](59+2(6)) = 71[/tex] ounces.

b) To find the percentage of widget weights that lie between 53 and 71 ounces, we need to find the z-scores for each value and use a standard normal distribution table to find the areas under the curve.

The z-score for [tex]53[/tex] ounces is: [tex](53-59)/6 = -1.00[/tex]

The z-score for [tex]71[/tex] ounces is: [tex](71-59)/6 = 2.00[/tex]

Using a standard normal distribution table, we can find the area to the left of each z-score:

The area to the left of [tex]z = -1.00[/tex] is 0.1587

The area to the left of [tex]z = 2.00[/tex] is 0.9772

To find the percentage of widget weights between [tex]53[/tex] and [tex]71[/tex] ounces, we can subtract the area to the left of [tex]z = -1.00[/tex] from the area to the left of [tex]z = 2.00[/tex] and multiply by [tex]100[/tex]:

Percentage [tex]= (0.9772 - 0.1587) * 100 = 81.85[/tex]%

Therefore, approximately [tex]81.85[/tex]% of the widget weights lie between 53 and [tex]71[/tex] ounces.

c) To find the percentage of widget weights that lie above [tex]41[/tex] ounces, we need to find the z-score for [tex]41[/tex] and use a standard normal distribution table to find the area to the right of the z-score.

The z-score for 41 ounces is: [tex](41-59)/6 = -3.00[/tex]

Using a standard normal distribution table, we can find the area to the right of [tex]z = -3.00[/tex]:

The area to the right of [tex]z = -3.00[/tex] is [tex]0.0013[/tex]

To find the percentage of widget weights above [tex]41[/tex]ounces, we can multiply the area to the right of [tex]z = -3.00[/tex] by [tex]100[/tex]:

Percentage [tex]= 0.0013 * 100 = 0.13[/tex]%

Therefore, approximately [tex]0.13[/tex] % of the widget weights lie above [tex]41[/tex]ounces.

Between the widget's weight of 0.13 and its weight in ounces, there is an 68 % company breadth.

What do you mean by the term percentage?

Percentage is a way of expressing a quantity or value as a fraction of 100. It is denoted by the symbol %, which means "per cent" or "out of 100"

a) Using the Empirical Rule, we know that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, approximately 95% of the data falls within two standard deviations of mean, and approximately 99.7% of the data falls within three standard deviations of mean.

Since the mean weight of the widgets is 59 ounces and the standard deviation is 6 ounces, we can use the Empirical Rule to determine that:

Approximately 68% of the widget weights lie between 53 and 65 ounces (one standard deviation below and above the mean).

Approximately 95% of widget weights lie between 47 and 71 ounces.

Approximately 99.7% of widget weights lie between 41 and 77 ounces.

b) To find the percentage of widget weights that lie between 53 and 71 ounces, we can use the Empirical Rule and subtract the percentage of widget weights that lie outside of this range from 100%.

we can estimate that approximately 68% of the widget weights lie between 53 and 71 ounces.

Therefore, the percentage of widget weights that lie between 53 and 71 ounces is approximately 68%.

c) To find the percentage of widget weights that lie above 41 ounces, we can use the Empirical Rule and subtract the percentage of widget weights that lie within three standard deviations below the mean from 100%.

Therefore, the percentage of widget weights that lie above 41 ounces is approximately:

100% - 99.7% = 0.3%

So, approximately 0.3% of the widget weights lie above 41 ounces.

Answers

The two expressions are not equivalent.

To simplify the expression (p^2n^1/2)^0 √ p^5n^4, we first need to understand the properties of exponents and radicals.

Recall that any number raised to the power of zero is equal to 1, so (p^2n^1/2)^0 = 1.

Next, we can simplify the radical term by multiplying the exponents inside and outside the radical:

√ p^5n^4 =

(p^5n^4)^(1/2)

= p^(5/2)n^(4/2)

= p^(5/2)n^2

Combining this result with the previous step, we have:

(p^2n^1/2)^0 √ p^5n^4

= 1 * p^(5/2)n^2

= p^(5/2)n^2

This is not equivalent to p^18n^6 √p. In fact, p^(5/2)n^2 cannot be simplified any further without additional information about the expression.  ,

where c is the side οppοsite angle C, a and b are the οther twο sides, and C is the angle between sides a and b.

Substituting the knοwn values:

26² = x² + (x+7)² - 2x(x+7) cοs(52°)

Simplifying and sοlving fοr x:

676 = x² + x² + 14x + 49 - 2x² cοs(52°) - 14x cοs(52°)

676 = 2x² - 14x cοs(52°) + 49

2x² - 14x cοs(52°) - 627 = 0

Using the quadratic fοrmula:

[tex]x = [14 cos(52^\circ) \± \sqrt{((14 cos(52^\circ))}^2 - 4(2)(-627))] / (2(2))[/tex]

x ≈ 15.7 οr x ≈ -21.6

Since x represents a length, we can discard the negative sοlutiοn and cοnclude that x ≈ 15.7.

A survey showed that 75% of adults need correction for their eyesight. If 12 adults are randomly selected find the probability that no more than one of them need correction of her eyesight is 18 significantly low number of adult record I said correction.

Answers

The probability that no more than one of them need correction of her eyesight is 5.960.

What is probability?

Probability is a way of calculating how likely something is to happen. It is difficult to provide a complete prediction for many events. Using it, we can only forecast the probability, or likelihood, of an event occurring. The probability might be between 0 and 1, where 0 denotes an impossibility and 1 denotes a certainty.

Here using formula , Binomial distribution: P(X) = [tex]nC_x \times p^x\times q^{n-x}[/tex]

=> P(an adult need correction), p = 0.75

=>q = 1 - p = 0.25

Sample size, n = 12

P(no more than 1 of them need correction for their eyesight) = P(none of them need correction) + P(only 1 need correction)

=> [tex]0.25^{12}[/tex] + [tex]12\times0.75\times0.25^{11}[/tex]

=> 5.960

If the probability of an event is less than 0.05, it can be considered significantly low

Therefore, 1 is a significantly low number of adults requiring eyesight​ correction.

A 25% orange juice drink is mixed with a 100% orange juice drink. The function f(x) = (4)(1.0)+z(0.25)
models the
4+z
concentration of orange juice in the drink after a gallons of the 25% drink are added to 4 gallons of pure juice.
What will be the concentration of orange juice in the drink if 2 gallons of 25% drink are added? Give the answer as a percent
but do not include the percent sign (%).

Answers

To solve the problem, we need to use the given function f(x) = 4 + z(0.25) where x is the amount of 25% orange juice drink added and z is the amount of 100% orange juice drink added.

We know that initially 4 gallons of pure juice are present. So, the total amount of juice in the mixture is 4 + x gallons.

When we add 2 gallons of 25% orange juice drink, x = 2 and z = 0. So, using the function f(x), we get:

f(2) = 4 + z(0.25)

    = 4 + 0(0.25)

    = 4

Therefore, the concentration of orange juice in the drink after adding 2 gallons of 25% orange juice drink is 4%, expressed as a percent but without the percent sign.

Answers

[tex](-20, -4)[/tex] and are all of the ordered pairings that fulfil this equation [tex]F = 9/5C + 32. (-10, 14)[/tex].

What exactly are equation, and what varieties exist?

Lines come in two varieties: identities and dependent equations. All possible values of the parameters result in an identity. Only certain combinations of the variables' values render a conditional equation true. Two expressions joined by the equals symbol ("=") form an equations.

What basic equation structure is used?

Ax+By=C is the classic pattern for two-variable linear equations. A typical form linear equation is, for instance, 2x+3y=5. Finding all intercepts of a solution in this format is not too difficult. The approach additionally proves useful when trying to solve solutions combining two linear systems.

To find the missing y values, we need to substitute the given [tex]x[/tex] values into the equation [tex]F = 9/5C + 32[/tex] and solve for [tex]F[/tex].

For the first ordered pair (-20, F1):

[tex]F1 = 9/5(-20) + 32[/tex]

[tex]F1 = -36 + 32[/tex]

[tex]F1 = -4[/tex]

So the missing y value is [tex]-4[/tex], and the complete ordered pair is [tex](-20, -4)[/tex].

For the second ordered pair (-10, F2):

[tex]F2 = 9/5(-10) + 32[/tex]

[tex]F2 = -18 + 32[/tex]

[tex]F2 = 14[/tex]

So the missing y value is [tex]14[/tex], and the complete ordered pair is [tex](-10, 14)[/tex].

Therefore, the complete set of ordered pairs that satisfy the equation [tex]F = 9/5C + 32[/tex] is:

[tex](-20, -4)[/tex] and [tex](-10, 14)[/tex].

Suppose the weights of sumo wrestlers are normally distributed with a mean of 330lbs and a standard deviation of 15lbs. An up and coming competitor wants to defeat wrestlers whose weights are in the top 10%. What is the minimum weight of the sumo wrestlers at the highest weight of the league? Round your answer to the nearest whole number, if necessary.

Answers

Answer: To find the weight of the sumo wrestlers at the highest 10%, we need to find the z-score that corresponds to the top 10% of the distribution.

Using a standard normal table or a calculator, we can find that the z-score that corresponds to the top 10% is approximately 1.28.

Next, we can use the formula for a z-score to find the weight that corresponds to this z-score:

z = (x - mu) / sigma

where z is the z-score, x is the weight we want to find, mu is the mean weight, and sigma is the standard deviation.

Substituting in the values we know, we get:

1.28 = (x - 330) / 15

Solving for x, we get:

x = 1.28(15) + 330 = 349.2

Rounding to the nearest whole number, the minimum weight of the sumo wrestlers at the highest weight of the league is 349 lbs.

Suppose that diastolic blood pressure readings of adult males have a bell-shaped distribution with a mean of 80 mmHg and a standard deviation of 9 mmHg. Using the empirical rule, what percentage of adult males have diastolic blood pressure readings that are less than 62 mmHg? Please do not round your answer.

Answers

95% of adult males have diastolic blood pressure readings that are at least 62 mmHg

The empirical rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean. The empirical rule is further illustrated below

68% of data falls within the first standard deviation from the mean.

95% fall within two standard deviations.

99.7% fall within three standard deviations.

From the information given, the mean is 80 mmHg and the standard deviation is 9 mmHg.

95% fall within two standard deviations.

2*9=`18

80 - 18 = 62 mmHg

Therefore, 95% of adult males have diastolic blood pressure readings that are at least 62 mmHg.

A cash prize of $3800 is to be awarded at a fundraiser. If 1900 tickets are sold at $4 each, find the expected value. Round your answer to the nearest cent
The expected value is dollars.

Answers

Answer:

The total amount of money collected from selling tickets is: 1900 tickets × $4/ticket = $7,600 Since the cash prize is $3,800, the expected value can be calculated as follows: Expected value = (Probability of winning) × (Cash prize) + (Probability of losing) × (Cost of ticket) The probability of winning is 1 out of 1900 tickets sold, or 1/1900. The probability of losing is 1899/1900. So, the expected value is: (1/1900) × $3,800 + (1899/1900) × $4 = $1.999 Rounding to the nearest cent, the expected value is $2.00.
