The experimental probability of selecting a green marble on the next attempt is 1/6 or approximately 0.1667 or 16.67%.

What is probability?

Probability is a measure of the likelihood of an event occurring.

The experimental probability of an event happening is calculated by dividing the number of times the event occurs by the total number of trials or attempts.

In this case, Diane has already selected 2 green marbles and 10 other marbles from the bag. So, the total number of marbles left in the bag is 12.

Since there are 2 green marbles left in the bag, the probability of selecting a green marble on the next attempt is:

2 (number of green marbles) / 12 (total number of marbles) = 1/6

So, the experimental probability of selecting a green marble on the next attempt is 1/6 or approximately 0.1667 or 16.67%.

Answer:

1)55 and for 2) 35

Step-by-step explanation:

All you have to do is and for perimeter.

The required probability of 911 calls are as follow,

For all six calls are emergency is equals to 0.000001.

For two or more calls are not emergencies is 0.999999.

Smallest number of calls for at least one emergency call is 20.

Probability that all six calls are emergencies is,

P(all six are emergencies) = (0.15)^6

                                           ≈ 0.000001

Probability that all six calls are emergencies is approximately 0.000001.

Probability that two or more calls are not emergencies,

Calculate it by the complement of the probability that all six calls are emergencies, and then subtracting this from 1,

P(at least two are not emergencies)

= 1 - P(all six are emergencies)

= 1 - (0.15)^6

≈ 0.999999

Probability that two or more calls are not emergencies is approximately 0.999999.

Let X be the number of calls that need to be answered to be at least 96%.

At least one call is an emergency.

Calculate the smallest value of X ,

P(at least one call is an emergency) ≥ 0.96

Using the complement rule,

P(no call is an emergency) ≤ 1 - 0.96 = 0.04

Each call is independent,

Probability that no call is an emergency can be calculated as,

P(no call is an emergency) = 0.85^X

Solve the inequality,

0.85^X ≤ 0.04

Taking logarithms of both sides, we get,

X log(0.85) ≤ log(0.04)

X ≥ log(0.04) / log(0.85)

X ≥ 19.83

Smallest number of calls that the 911 operators need to answer to be at least 96% sure that at least one call is an emergency is 20.

Therefore, the required probability for the 911 calls with 85% not emergency is given by ,

probability of all six calls are emergency is 0.000001.

probability of two or more calls are not emergencies is 0.999999.

required smallest number of calls for at least one emergency call is 20.

We can find y by solving for the length of CN: CN = Sy - BC = 600 - 0 = 600 So the values of x and y are:
x = 0 , y = 600

First, we can look at the corresponding sides of triangle ABC and triangle MNC. Since we know that these triangles are

similar (as indicated by the ~ symbol), we can set up the following proportion:

AB/AM = BC/CN

We can substitute in the given values for these lengths:

4x/2x = (Lv + Sy)/Sy

Simplifying this equation, we can cancel out the common factor of 2x on the left side:

2 = (Lv + Sy)/Sy

Multiplying both sides by Sy, we can isolate the sum of Lv and Sy:

2Sy = Lv + Sy

Combining like terms, we get:

Sy = Lv

So we now know that Sy is equal to Lv, which is 600.

To solve for x and y, we can use the fact that corresponding sides are in proportion. Specifically, we can look at the ratio of the length of AB to the length of AM:

AB/AM = 4x/Lv

Substituting in the values we know, we get:

AB/AM = 4x/600

We can also look at the ratio of the length of BC to the length of CN:

BC/CN = 2x/Sy

Substituting in the values we know, we get:

BC/CN = 2x/600

Since AB and BC are corresponding sides in triangle ABC and AM and CN are corresponding sides in triangle MNC, we

know that these ratios must be equal:

4x/600 = 2x/600

Simplifying this equation, we get:

4x = 2x

Subtracting 2x from both sides, we get:

2x = 0

Dividing both sides by 2, we get:

x = 0

Since x is 0, we can't solve for it any further. However, we can solve for y by using the ratio we found earlier:

AB/AM = 4x/600 = 0/600 = 0

Since AB is 0, we know that BC is also 0 (since the sum of the lengths of the sides of a triangle must be greater than 0).

a. The two parameters of the gamma distribution are

shape parameter (α) and velocity parameter (β).

The mean of the gamma distribution = α/β and the standard deviation = sqrt(α)/β.

mean = 5 seconds

standard deviation =2.5 seconds.

α/β = 5 (equation 1)

sqrt(α)/β = 2.5 (equation 2)

Squaring equation 2 and multiplying both sides by β^2 yields:

[tex]α = 6.25β^2[/tex]

Substituting this value of α into Equation 1 yields:

[tex]6.25β^2/β = 5[/tex]

Simplified, it looks like this:

β = 0.8

Substituting this value of β into Equation 1 yields:

a = 4

Therefore, the parameters of the gamma distribution are α = 4 and β = 0.8.

b. I need to find the probability that this software will take more than 10 seconds to run.

The probability density function (PDF) of the gamma distribution is given by

[tex]f(x) = (β^α * x^(α-1) * e^(-βx)) / Γ(α)[/tex]

where Γ(α) is the gamma function.

Using the values ​​of α and β obtained in part (a), we can write the PDF as

[tex]f(x) = (0.8^4 * x^(4-1) * e^(-0.8x)) / Γ(4)[/tex]

I need to find the probability that the execution time exceeds 10 seconds. This can be written as:

P(X > 10) = ∫(10 to infinity) f(x) dx

Using software or a calculator, we can evaluate this integral to get:

P(X > 10) = 0.0559 (rounded to four decimal places)

Therefore, the probability is 0.0559.

c.Since it has already taken more than 5 seconds, we need to find the probability of this software where will take more than 10 seconds to run.

This is a conditional probability and should be calculated using Bayes' theorem.

P(X > 10 | X > 5) = P(X > 10 and X > 5) / P(X > 5)

The numerator can be simplified to

P(X > 10 and X > 5) = P(X > 10)

Using the results obtained in part (b), we can write

P(X > 10 and X > 5) = 0.0559

The denominator can be written as:

P(X > 5) = ∫(5 to infinity) f(x) dx

Using the same PDF as before, we can evaluate this integral and get:

P(X > 5) = 0.2615 (rounded to four decimal places)

Substituting these values ​​into the conditional probability formula gives:

P(X > 10 | X > 5) = 0.0559 / 0.2615

Simplified, it looks like this:

P(X > 10 | X > 5) = 0.214

Therefore, the probability that his single run of this software took longer than 5 seconds to take longer than 10 seconds is 0.214 (rounded to three decimal places).

the equation y=1 does not represent a direct variation, whereas the other three equations given do represent direct variation.

What is Direct variation?

Direct variation is a relationship between two variables in which one is a constant multiple of the other. This means that if one variable increases, the other variable will also increase by a proportional amount. In other words, direct variation can be represented by the equation y=kx, where k is the constant of variation.

Out of the four equations given, the equation y=1 does not represent a direct variation. This is because the equation is not a function of x. In other words, no matter what value of x we choose, y will always be equal to 1. This means that the two variables, x and y, are not related to each other in any way. Therefore, there is no constant k that can be multiplied by x to get y.

On the other hand, the other three equations do represent direct variation. For example, in the equation y=x, y is equal to x multiplied by the constant k=1. Similarly, in the equation y=-5x, y is equal to x multiplied by the constant k=-5. Finally, in the equation y=0.9x, y is equal to x multiplied by the constant k=0.9.

In summary, the equation y=1 does not represent a direct variation, whereas the other three equations given do represent direct variation.

Step-by-step explanation:

To graph the boundary lines of the linear inequalities, we need to first set up the inequalities based on the given information. Let x be the number of popcorn bags and y be the number of cotton candy bags. Then we have:

Chris needs at least 7 bags of popcorn, so the inequality for popcorn is x ≥ 7.

Chris has $56 to spend, so the total cost of popcorn and cotton candy cannot exceed $56, which gives the inequality 3x + 7y ≤ 56.

To graph the boundary lines, we need to first graph the lines corresponding to these two inequalities:

The line x = 7 is a vertical line passing through the point (7,0), because the only restriction on the popcorn is that Chris needs at least 7 bags.

The line 3x + 7y = 56 is a diagonal line with x-intercept 56/3 and y-intercept 8, because these are the points where the line intersects the x and y axes, respectively.

We can now plot these lines on a coordinate plane:

The shaded region below and to the left of the diagonal line represents the solution set to the inequalities, because it includes all the points where Chris can buy at least 7 bags of popcorn and stay within his budget.

Finally, we can plot the given points and identify which ones are part of the solution set:

(3, 7) is not part of the solution set because it is above the diagonal line.

(2, 2) is part of the solution set because it is below and to the left of the diagonal line.

(8, 1) is not part of the solution set because it is above the diagonal line.

(10, 2) is not part of the solution set because it is above the diagonal line.

(5, 5) is part of the solution set because it is below and to the left of the diagonal line.

Therefore, the solution set consists of the points (2, 2) and (5, 5).

x² - 3x = 1

x² - 3x + 9/4 = 1 + 9/4

We have verified the identity of the expression 1 + cos(x) / cot(x) + cos(x) = sec(x) using the Pythagorean Identity.

The mathematical subject of trigonometry is the study of the connections between the angles and sides of triangles.

let's rewrite the expression using sine and cosine:

1 + cos(x) / cot(x) + cos(x) = sec(x)

cot(x) is the same as cos(x)/sin(x), so we can substitute:

1 + cos(x) / (cos(x)/sin(x)) + cos(x) = sec(x)

Simplifying the expression in the denominator:

1 + cos(x) * (sin(x)/cos(x)) + cos(x) = sec(x)

Canceling out the cos(x) terms in the numerator:

1 + sin(x) + cos(x) = sec(x)

Now, let's use the Pythagorean Identity:

sin²(x) + cos²(x) = 1

Divide both sides by cos²(x):

tan²(x) + 1 = sec²(x)

Substitute tan(x) for sin(x)/cos(x):

(sin²(x)/cos²(x)) + 1 = sec²(x)

Multiply both sides by cos²(x):

sin²(x) + cos²(x) = cos²(x)sec²(x)

Substitute cos²(x) with 1 - sin²(x):

sin²(x) + (1 - sin²(x)) = (1 - sin²(x))sec²(x)

Simplify:

1 = sec²(x)

Taking the square root of both sides:

1 = sec(x)

The difference in the account balance between a simple interest and a compound interest over an 8-year time period, rounded to the nearest cent, is $12,189.02.

To calculate the difference in the account balance between simple interest and compound interest over 8 years, we first need to determine the final balance for each case.

Simple Interest:

Simple interest is calculated as a percentage of the initial principal (or the original amount deposited) and is paid only on the principal amount. The formula for simple interest is:

I = P * r * t

where I is the interest earned, P is the principal amount (in this case, $5,000), r is the annual interest rate (as a decimal), and t is the time period in years.

For this problem, the interest rate is given as 31%, which is equivalent to 0.31 as a decimal. Therefore, we have:

I = $5,000 * 0.31 * 8 = $12,400

The final balance for simple interest is the sum of the principal and the interest earned:

Final balance (simple interest) = $5,000 + $12,400 = $17,400

Compound Interest:

Compound interest is interest that is calculated on both the principal amount and any accumulated interest. The formula for compound interest is:

A = P * (1 + r/n)^(n*t)

where A is the final amount, P is the principal amount, r is the annual interest rate (as a decimal), n is the number of times per year that interest is compounded, and t is the time period in years.

For this problem, the interest rate is 31% and the account is compounded annually, so n = 1. Therefore, we have:

A = $5,000 * (1 + 0.31/1)^(1*8) = $29,589.02

The final balance for compound interest is the amount we just calculated:

Final balance (compound interest) = $29,589.02

The difference in the two account balances is:

$29,589.02 - $17,400 = $12,189.02

Therefore, the difference in the account balance between a simple interest and a compound interest over an 8-year time period, rounded to the nearest cent, is $12,189.02.

Answer:

The volume of a cylinder is given by the formula: V = πr^2h where r is the radius and h is the height. Substituting the given values, we get: V = π(4 in)^2(3 in) V = π(16 in^2)(3 in) V = 48π in^3 Therefore, the volume of wax needed to make one candle is 48π cubic inches. To find the amount of wax needed for 120 candles, we can multiply the volume of one candle by the number of candles: Amount of wax = 48π in^3/candle × 120 candles Amount of wax = 5760π in^3 So the company will need 5760π cubic inches of wax to make 120 candles.

The ball was thrown 11 m off the ground. The maximum height of the ball was 11 m. The height of the ball at 2.5s was 9.07 m. Yes, the football is in the air after 6s and the ball hits the ground at 8.67 s.

Height is the measure of vertical distance or the vertical extent of an object, person, or other thing from top to bottom. It is typically measured in units of meters or feet. Height is a measure of vertical distance or elevation above a given level, most commonly sea level. Height can also be determined by measuring the altitude of an object or location. Height is an important factor in many everyday contexts, such as architecture and sports.

To calculate the answers, we must first solve for the equation of the height of the ball h(t).

h(t) = -4.9(1-1.39)² + 11

1) The ball was thrown 11 m off the ground.

To calculate this, we set t = 0.

h(0) = -4.9(1-1.39)² + 11

h(0) = 11

Therefore, the ball was thrown 11 m off the ground.

2) The maximum height of the ball was 11 m.

To calculate this, we set the derivative of the equation, h'(t) = 0 and solve for t.

h'(t) = -9.8(1-1.39)

h'(t) = 0

1-1.39 = 0

1 = 1.39

Therefore, t = 1.

Substituting t = 1 into the equation for h(t), we get:

h(1) = -4.9(1-1.39)² + 11

h(1) = 11

Therefore, the maximum height of the ball was 11 m.

3) The height of the ball at 2.5s was 9.07 m.

To calculate this, we substitute t = 2.5 into the equation for h(t).

h(2.5) = -4.9(1-1.39)² + 11

h(2.5) = 9.07

Therefore, the height of the ball at 2.5s was 9.07 m.

4) Yes, the football is in the air after 6s.

To calculate this, we substitute t = 6 into the equation for h(t).

h(6) = -4.9(1-1.39)² + 11
+ 11

h(8.67) = 0

Therefore, the ball hits the ground at 8.67 s.

In conclusion, the ball was thrown 11 m off the ground. The maximum height of the ball was 11 m. The height of the ball at 2.5s was 9.07 m. Yes, the football is in the air after 6s and the ball hits the ground at 8.67 s.

The height of the rocket at a time of 7.8 seconds is approximately 2,254 feet.

To find a quadratic regression equation, we need to fit a quadratic function of the form [tex]y = ax^2 + bx + c[/tex]to the data.

Using a calculator or spreadsheet software, we can find the coefficients that minimize the sum of the squared errors between the predicted values of y and the actual values of y.

The resulting quadratic regression equation is:

[tex]y = 88.6x^2 + 2.9x + 196.5[/tex]

To find the height of the rocket at a time of 7.8 seconds, we simply substitute x = 7.8 into the equation and evaluate:

[tex]y = 88.6(7.8)^2 + 2.9(7.8) + 196.5[/tex]

y ≈ 2,253.6

Rounding to the nearest foot, we get:

y ≈ 2,254 feet

Therefore, the height of the rocket at a time of 7.8 seconds is approximately 2,254 feet.

The value of x in the given inequality is x is greater than or equal to 16.

Using symbols like (less than), > (greater than), (less than or equal to), or (greater than or equal to), an inequality compares two values or expressions and illustrates their connection (not equal to). When values or phrases are being compared, it is said that there exist inequalities. For instance, the inequality x + 2 7 signifies that "x plus 2 has a value less than 7."

The given inequality is x - 4 ≥ 12.

Add 4 on both sides of the inequality:

x - 4 + 4 ≥ 12 + 4

x ≥ 16

Hence, the value of x in the given inequality is x is greater than or equal to 16.

Answer:

y = [tex]\frac{4}{3}[/tex]x - 3

Step-by-step explanation:

Oof... I haven't done this in a while, but here you go! Slope-intercept form is y=mx+b, and in this one, the y-intercept is -3, just to get that out of the way. Now, the slope is the rise over the run, and I'm going to use the points (3, 1) and (6, 5) to measure the rise and run. The change in y, or the rise, is 4, while the change in x, or the run, is 3, so the slope is 4/3. Hope this was helpful!

Answer:

[tex]y = \dfrac{4}{3}x - 3[/tex]

Step-by-step explanation:

The slope-intercept form of a line is defined as:

[tex]y=mx+b[/tex],

where [tex]m[/tex] is the line's slope, and [tex]b[/tex] is the y-coordinate of its y-intercept.

We can see that the slope of the line is:

slope = rise / run = 4/3

(See the attached image for a model of rise and run.)

We can also see that the line touches the y-axis when y = -3, so this is the y-coordinate of the line's y-intercept.

With these pieces of information, we can craft the line's equation in slope-intercept form:

[tex]y = \dfrac{4}{3}x - 3[/tex]
