(iii) If 24 college graduates were hired by companies, how many are expected to stay with the same company for more than five years. ​​(2 marks)


(iv) Describe the shape of this distribution. Justify your answer using the relevant statistics

Answers

Answer 1

The probability that exactly 2 out of 15 college graduates stay with the same company 0.0246,  the probability that more than 3 out of 15 college graduates stay with the same company is 0.0567, 2 college graduates would stay in the company and the shape of the binomial distribution is approximately normal

(i) To find the probability that exactly 2 out of 15 college graduates stay with the same company for more than five years, we use the binomial probability formula:

P(X = 2) = (15 choose 2) * (0.08)^2 * (0.92)^13

         = 105 * 0.0064 * 0.3369

         ≈ 0.0246

So the probability, rounded to four decimal places, is 0.0246.

(ii) To find the probability that more than 3 out of 15 college graduates stay with the same company for more than five years, we can use the complement rule and find the probability of 3 or fewer staying with the same company, and then subtract that from 1:

P(X > 3) = 1 - P(X ≤ 3)

        = 1 - [P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)]

        = 1 - [(15 choose 0) * (0.08)^0 * (0.92)^15 + (15 choose 1) * (0.08)^1 * (0.92)^14 + (15 choose 2) * (0.08)^2 * (0.92)^13 + (15 choose 3) * (0.08)^3 * (0.92)^12]

        ≈ 0.0567

So the probability, rounded to four decimal places, is 0.0567.

(iii) If 8% of all college graduates hired by companies stay with the same company for more than five years, then we would expect 0.08 * 24 = 1.92 college graduates to stay with the same company for more than five years. Since we cannot have a fractional number of college graduates, we would expect 2 college graduates to stay with the same company for more than five years.

(iv) The distribution of the number of college graduates staying with the same company for more than five years follows a binomial distribution. This is because each college graduate either stays with the same company for more than five years or they do not, and the probability of success (staying with the same company for more than five years) is constant for all college graduates.

The shape of the binomial distribution is approximately normal, provided that both np and n(1-p) are greater than or equal to 10, where n is the sample size and p is the probability of success. In this case, np = 15 * 0.08 = 1.2 and n(1-p) = 15 * 0.92 = 13.8, which are both greater than or equal to 10, so we can assume that the distribution is approximately normal.

Q 28 : A new school has built lockers for its students. All the digits from 0 to 9, together with


the letters A to Y, have been used to identify the lockers. Only 4 digits have been used to


identify the lockers with the letter Z. How many lockers have been built in this school, if each


locker is identified by one letter and one digit?

Answers

If each locker is identified by one letter and one digit, the total number of lockers built in the school is 229.

There are 26 letters in the alphabet (A to Z), and if each locker is identified by one letter and one digit, then there are a total of 26 × 10 = 260 possible locker identifications using the letters A to Y and digits 0 to 9.

Out of these, there are 4 digits used to identify the lockers with the letter Z. So, there are 10 − 1 = 9 digits left to use for the remaining lockers, as we cannot use the digit already used for the lockers with the letter Z.

Similarly, there are 25 letters left to use for the remaining lockers, as we cannot use the letter Z.

Therefore, the number of remaining lockers is 9 × 25 = 225. Adding the 4 lockers with the letter Z, the total number of lockers built in the school is 225 + 4 = 229.

To map triangle ABC to triangle A'B'C', you would need to follow a specific sequence of transformations, which may include translation, rotation, and reflection. Here's a step-by-step explanation:

Step 1: Translation
Translate triangle ABC by a specific vector (x, y) so that point A moves to point A'. The same vector will also move points B and C to their corresponding new positions.

Step 2: Rotation
If triangle A'B'C' is rotated compared to the translated triangle, rotate the translated triangle around point A' by a specific angle, either clockwise or counterclockwise, until point B aligns with point B'.

Step 3: Reflection
If triangle A'B'C' is a mirror image of the rotated triangle, reflect the rotated triangle across a line of symmetry (usually a line passing through A'). This will change the orientation of the triangle and align point C with point C'.

By following these transformations in sequence, you can map triangle ABC to triangle A'B'C'. Keep in mind that the specific details of translation, rotation, and reflection will depend on the coordinates and orientation of the given triangles.

The demand function for an exclusive wool blanket is given byp=D(x)=33-2√x dollars, where x is in thousands of blankets. Findthe level of production for which the demand is elastic

Answers

To maximize the company's profit, we need to find the profit function and then differentiate it with respect to the quantities produced by each plant to find the optimal values.

The profit function is given by:

π = TR - TC

where TR is the total revenue and TC is the total cost.

Using the demand function p = 40 - 0.04q, we can express the total revenue as:

TR = p * q = (40 - 0.04q) * q = 40q - 0.04q²

The total cost is the sum of the costs of each plant, so we have:

TC = C1 + C2 = 6.7 + 0.03q1² + 7.9 + 0.04q2² = 14.6 + 0.03q1² + 0.04q2²

Substituting these expressions into the profit function, we get:

π = 40q - 0.04q² - 14.6 - 0.03q1² - 0.04q2²

To find the optimal values of q1 and q2, we differentiate the profit function with respect to each quantity and set the derivatives equal to zero:

∂π/∂q1 = 40 - 0.06q1 - 0.04q2 = 0

∂π/∂q2 = 40 - 0.03q2 - 0.04q1 = 0

Solving these equations, we get:

q1 = 357.14

q2 = 285.71

So each plant should produce 357.14 and 285.71 units of the item, respectively, in order to maximize the company's profit.

Annmarie can plow a field in 240 minutes. Gladys can plow a field 80 minutes faster. If they work together, how many minutes does it take them to plow the field?

Answers

It would take Annmarie and Gladys 96 minutes to plow the field together.

How long to plow field together?

Annmarie can plow a field in 240 minutes. Gladys can plow the same field 80 minutes faster than Annmarie.

So Gladys can plow the field in 240 - 80 = 160 minutes.

Let x be the time it takes for both of them to plow the field together.

The combined rate of Annmarie and Gladys is the sum of their individual rates.

Annmarie's rate is 1 field per 240 minutes, which is 1/240 field per minute.

Gladys's rate is 1 field per 160 minutes, which is 1/160 field per minute.

Their combined rate is:

1/240 + 1/160 = 1/x

Simplifying this equation:

1/x = (4/960) + (6/960) = 10/960

1/x = 1/96

Multiplying both sides by 96, we get:

x = 96 minutes

Therefore, it would take Annmarie and Gladys 96 minutes to plow the field together.

Use any method to determine whether the series converges а. น k2 sk (5 pts) b 6. Ex 2+(-1){ 5k (5 pts)"

Answers

To determine whether the series น k2 sk converges, we can use the Integral Test. Let f(x) = x2, then f'(x) = 2x. Since 2x is continuous, positive, and decreasing on [1,∞), In summary, the series Σ (1/k^2) converges, while the series Σ (2 + (-1)^{5k}) does not converge.

∫1∞ f(x) dx = ∫1∞ x2 dx = lim (t → ∞) [1/3 x3]1t = ∞
Since the integral diverges, the series น k2 sk also diverges.
b. To determine whether the series 2+(-1){ 5k converges, we can use the Alternating Series Test. The series has alternating signs and the absolute value of each term decreases as k increases. Let ak = 2+(-1){ 5k, then:
|ak| = 2+1/32k ≤ 2
Also, lim (k → ∞) ak = 0. Therefore, by the Alternating Series Test, the series 2+(-1){ 5k converges.

a. For the series Σ (1/k^2) (denoted as น k2 sk), we can use the p-series test. A p-series is a series of the form Σ (1/k^p), where p is a constant. If p > 1, the series converges, and if p ≤ 1, the series diverges. In this case, p = 2, which is greater than 1. Therefore, the series Σ (1/k^2) converges.
b. For the series Σ (2 + (-1)^{5k}), we can use the alternating series test. An alternating series is a series that alternates between positive and negative terms. In this case, the series alternates because of the (-1)^{5k} term. However, the series does not converge to zero as k goes to infinity, since there is a constant term 2. Therefore, the series Σ (2 + (-1)^{5k}) does not converge.
In summary, the series Σ (1/k^2) converges, while the series Σ (2 + (-1)^{5k}) does not converge.

A restaurant needs a block of ice that is exactly 480 cubic inches in volume
The height of the ice block must be 10 inches. Pls help is this right ????

Answers

The height of the ice block must be 10 inches, the length and width could be any combination of dimensions that multiply together to equal 48 square inches.

Explain volume?

The overall number of cube units that the cube totally occupies is the definition of a cube's volume. Volume is simply the total amount of space an object takes up. The cube's volume can be calculated using the formula a3 where an is the cube's edge.

given,

To check if the height of the ice block must be 10 inches to have a volume of 480 cubic inches, we can use the formula for the volume of a rectangular solid:

V = l * w * h

where l represents the length, w represents the measurement of width, while h is the peak, and V is the volume.

Since the volume is given as 480 cubic inches, and the height is specified as 10 inches, we can write:

480 = l * w * 10

Dividing both sides by 10, we get:

48 = l * w

This means that the product of the length and width must be equal to 48 square inches in order for the block of ice to have a volume of 480 cubic inches with a height of 10 inches.

There are many possible dimensions that satisfy this condition. For example, the block of ice could have dimensions of 8 inches by 6 inches by 10 inches, or 12 inches by 4 inches by 10 inches, or 16 inches by 3 inches by 10 inches, and so on.

Jesse can mow 3 yards in 8 hours. Jackson can mow twice as many yards per hour. What is the constant of proportionality between the number of yards Jackson can mow and the number of hours?

Answers

If Jesse can mow 3 yards in 8 hours. Jackson can mow twice as many yards per hour the constant of proportionality between the number of yards Jackson can mow and the number of hours is 3/4.

To find the constant of proportionality between the number of yards Jackson can mow and the number of hours, we can use the formula:

k = y/x

where k is the constant of proportionality, y is the number of yards, and x is the number of hours.

We know that Jesse can mow 3 yards in 8 hours, which means his rate of mowing is: 3 yards/8 hours = 3/8 yards per hour

We also know that Jackson can mow twice as many yards per hour as Jesse, which means his rate of mowing is:

2 * (3/8) yards per hour = 3/4 yards per hour

Now we can use the formula to find the constant of proportionality for Jackson:

k = y/x = (3/4) yards per hour / 1 hour = 3/4

Therefore, the constant of proportionality between the number of yards Jackson can mow and the number of hours is 3/4.

Answers

If Joao scored a goal in 60% of the soccer games last season, then we can expect him to score a goal in about 60% of the games he plays this season.

So, if Joao plays in 10 games this season, we can estimate that he will score a goal in approximately 60% of those games.

To calculate the actual number of games he is expected to score a goal in, we can use the formula:

Expected number of goals = Total number of games x Probability of scoring a goal

Plugging in the numbers, we get:

Expected number of goals = 10 x 0.6 = 6

You pick a card at random.


What is P(even or prime)?



Write your answer as a percentage

Answers

Probability of picking an even or prime card at random is approximately 88.89%.

To find the probability of picking an even or prime card at random, we first need to identify the possible cards that meet these conditions.

In a standard deck of cards, there are 52 cards, but we only consider the numerical values, which are 2-10 for each of the four suits (hearts, clubs, spades, and diamonds).

Even numbers: 2, 4, 6, 8, 10

Prime numbers: 2, 3, 5, 7

Combining the even and prime numbers, we have: 2, 3, 4, 5, 6, 7, 8, 10. Note that 2 appears only once in the combined list.

Now we find the probability by dividing the number of favorable outcomes (even or prime numbers) by the total number of possible outcomes (cards numbered 2-10).

P(even or prime) = (Number of even or prime cards) / (Total number of cards from 2-10)

P(even or prime) = 8 / 9

To express the probability as a percentage, multiply by 100:

P(even or prime) = (8 / 9) × 100 ≈ 88.89%

a laundromat has 5 washing machines. a typical machine breaks down once every 5 days. a repairer can repair a machine in an average of 2.5 days. currently, three repairers are on duty. the owner of the laundromat has the option of replacing them with a superworker, who can repair a machine in an average of 5 6 day. the salary of the superworker equals the pay of the three regular employees. breakdown and service times are exponential. should the laundromat replace the three repairers with the superworker?

Answers

Replacing three repairers with a superworker would be cost-effective for the laundromat as the expected repair time would increase and lead to more downtime for the machines.

To determine if the laundromat should replace the three repairers with the superworker, we need to compare the expected repair time under each scenario.

With three repairers, the expected time to repair a machine is the sum of the expected time until a machine breaks down and the expected time for a repairer to fix it

E(time with three repairers) = 5 + 2.5/3 = 6.167 days.

With the superworker, the expected time to repair a machine is

E(time with superworker) = 5/6 = 0.833 days.

Therefore, on average, it takes much less time to repair a machine with the superworker than with three repairers. Since the salary of the superworker is equal to that of three repairers, the laundromat should replace the three repairers with the superworker. It is also more cost-effective.

You are throwing a birthday party and are ordering pizza for your guests! You are guessing there will be about 30 people in attendance. You have two options for pizzas! You have budgeted $215 for food so you want to go with the option that will give you the better deal. This means the option that gives you a cheaper price per square inch of pizza

Answers

Based on these calculations, option 1 gives you the cheaper price per square inch of pizza.

To determine which option will give you a cheaper price per square inch of pizza, you will need to compare the prices of the two options and calculate their respective prices per square inch.

Let's say option 1 is a large pizza with a diameter of 18 inches and costs $20, while option 2 is a medium pizza with a diameter of 14 inches and costs $15.

To calculate the area of each pizza, you need to use the formula for the area of a circle:

A = πr^2

For option 1, the radius is 9 inches (half of the diameter), so the area is:

A = π(9)^2 = 81π square inches

For option 2, the radius is 7 inches (half of the diameter), so the area is:

A = π(7)^2 = 49π square inches

Now you can calculate the price per square inch for each option by dividing the cost by the area:

Option 1:

Price per square inch = $20 / (81π) = $0.078/square inch

Option 2:

Price per square inch = $15 / (49π) = $0.098/square inch

Based on these calculations, option 1 gives you the cheaper price per square inch of pizza.

tommy solved the equation x ^²-x-12=0 select the factores of x^-x-12

Answers

The factored equation becomes: (x + 3)(x - 4).



——
First, find the 2 numbers that add to -1 and multiply to -12. The numbers are -4 and +3.
Split x^2 - x - 12 using these factors;
(x^2 + 3x)(-4x - 12)
Factor out x from terms in the first parentheses and factor out -4 from terms in the second set of parentheses.
x(x + 3) + -4(x + 3).
Take out the common term (x+3) and we are left with:
(x + 3)(x - 4).
x^2 - x - 12 factored = (x+3)(x-4)

Solve for x. −43x 16<79 drag and drop a number or symbol into each box to correctly complete the solution.

Answers

-43x < 79 - 16

How can the inequality −43x + 16 < 79 be solved?

To solve the inequality −43x + 16 < 79, we need to isolate the variable x.

Let's begin by subtracting 16 from both sides of the inequality:

−43x + 16 - 16 < 79 - 16

Simplifying the equation, we have:

−43x < 63

Next, we divide both sides of the inequality by -43. However, when we divide by a negative number, the direction of the inequality sign will be flipped:

x > 63 / -43

Simplifying further, we have:

x > -1.465

Therefore, the solution to the inequality is x > -1.465.

In interval notation, we can represent the solution as (-1.465, ∞), indicating that x is greater than -1.465 and extends indefinitely towards positive infinity.

Find the magnitude and direction of the vector u = <-4, 7>

Answers

The magnitude and direction of the vector u = <-4, 7> are |u| ≈ √65 and θ ≈ 119.74°.

To find the magnitude and direction of the vector u = <-4, 7>, we will use the following steps:

1. Calculate the magnitude using the Pythagorean theorem.
2. Calculate the direction using the arctangent function.

Step 1: Calculate the magnitude.
Magnitude (|u|) = √((-4)^2 + (7)^2) = √(16 + 49) = √65

Step 2: Calculate the direction (angle θ).
θ = arctan(opposite/adjacent) = arctan(7/-4) ≈ -60.26° (in degrees)
Since the vector is in the second quadrant, we need to add 180°.
θ = -60.26° + 180° ≈ 119.74°

So, the magnitude and direction of the vector u = <-4, 7> are |u| ≈ √65 and θ ≈ 119.74°.

Demand at the location can be either average or favourable with estimated probabilities to be 0. 35 and 0. 65 respectively. If demand is favorable, the store manager may choose to maintain the current size or to expand. The net present value of profits is $623,000 if the firm chooses not to expand. However, if the firm chooses to expand, there is a 75% chance that the net present value of the returns will be 330,000 and 25% chance the estimated net present value of profits will be $610,000. If a medium size supermarket is built and demand is average, there is no reason to expand and the net present value of the profits Is $600,000. However, if a large supermarket is built and the demand turns out to be average, the choice is to do nothing with a net present value of $100,000 or to stimulate demand through local advertising. The response to advertising can be either unfavorable with a probability of 0. 2 or faverable with a probability of 0. 8.
