Answer: To find the proportion of students who performed worse than Aaron, we need to find the area to the left of his score of 989 on the normal distribution curve.

First, we need to standardize Aaron's score using the formula:

z = (x - mu) / sigma

where x is the score, mu is the mean, and sigma is the standard deviation.

Plugging in the values, we get:

z = (989 - 1100) / 200 = -0.55

Next, we look up the area to the left of z = -0.55 on the standard normal distribution table, or use a calculator to find:

P(Z < -0.55) = 0.2912

Therefore, the proportion of students who performed worse than Aaron is approximately 0.2912, or 29.12% (rounded to 2 decimal places).

It will take approximately 1.59 hours to fill the hot tub with a hose that has a filling rate of 4.6 gallons per minute

Assuming that the filling rate of the hose is constant, we can use the formula:

time = volume / rate

where time is the time taken to fill the hot tub, volume is the volume of the hot tub (440 gallons), and rate is the filling rate of the hose (4.6 gallons per minute).

Substituting the values, we get:

time = 440 / 4.6

which simplifies to:

time = 95.65 minutes

To convert minutes to hours, we divide by 60 (since there are 60 minutes in an hour):

time = 95.65 / 60

which simplifies to:

time = 1.59 hours

Therefore, it will take approximately 1.59 hours to fill the hot tub with a hose that has a filling rate of 4.6 gallons per minute.

It will take approximately 1.594 hours to fill a 440-gallon hot tub with a hose that fills at a rate of 4.6 gallons per minute.

To determine how many hours follow these steps:

First, we need to find out how many minutes it takes to fill the hot tub.

Divide the total volume of the hot tub (440 gallons) by the rate at which the hose fills (4.6 gallons per minute):

440 gallons ÷ 4.6 gallons/minute = 95.65 minutes

Now, we need to convert the minutes into hours.

Since there are 60 minutes in an hour, divide the minutes by 60:

95.65 minutes ÷ 60 minutes/hour = 1.594 hours

It will take approximately 1.594 hours to fill a 440-gallon hot tub with a hose that fills at a rate of 4.6 gallons per minute.

Answer: Assuming a significance level of 0.05 for each hypothesis test, the probability of committing a Type I error (rejecting the null hypothesis when it is actually true) in any given test is 0.05.

Therefore, the expected number of Type I errors in 1,900 hypothesis tests is:

Expected number of Type I errors = (0.05) x (1,900) = 95

So, we would expect to commit a Type I error about 95 times in 1,900 hypothesis tests, assuming the null hypothesis were true.

Answer: A Rectangular prism 

Since the center of this semicircle is at the origin, O (0, 0), the radius of the semicircle is 5 units.

Since the center of this semicircle is at the point A (3, 4) and point B (-4, 5), the radius of the semicircle is 5√2 units.

In Mathematics and Geometry, the distance between two (2) points that are on a coordinate plane can be calculated by using the following mathematical equation (formula):

Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Where:

x and y represents the data points (coordinates) on a cartesian coordinate.

By substituting the given points into the distance formula, we have the following;

Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Distance = √[(3 - 0)² + (4 - 0)²]

Distance = √[(3)² + (4)²]

Distance = √(9 + 16)

Distance = √25

Distance = 5 units.

At point A (3, 4) and point B (-4, 5), the radius is given by;

Distance = √[(-4 - 3)² + (5 - 4)²]

Distance = √[(-7)² + (1)²]

Distance = √(49 + 1)

Under the direct method, Gaulle will report cash collected from customers of $35,000.cash collected from customers is determined by adding the changes in Accounts Receivable to the revenues recognized during the period.

Beginning Accounts Receivable was $6,000 and ending Accounts Receivable was $9,000, indicating that customers owed Gaulle an additional $3,000 during the year.

Revenue for the year was $38,000, which represents the total sales generated by the company during the period. To calculate the cash collected from customers, we need to subtract the change in Accounts Receivable from the revenue recognized during the period.

Therefore, the cash collected from customers for Gaulle is calculated as follows:

Cash collected from customers = Revenue - Decrease in Accounts Receivable

= $38,000 - ($9,000 - $6,000)

To determine which equation represents how much the worker earns in x hours, we can use the table to find the rate of pay per hour, which is the change in wages divided by the change in hours:

Change in wages = $105.50 - $25.50 = $80

Change in hours = 6 - 2 = 4

Rate of pay per hour = Change in wages / Change in hours

= $80 / 4

= $20

Therefore, the worker earns $20 per hour. To find the total earnings, we can multiply the hourly rate by the number of hours worked:

y = $20x

Therefore, the correct equation is D) y = 10x, which represents how much the worker earns in x hours.

If the degree of freedom is 24, your sample size when conducting a t-test for dependent means must be 25. Option C is the correct answer.

The sample size when conducting a t-test for dependent means depends on the specific study design and the level of significance desired, and cannot be determined solely based on the degrees of freedom.

However, if we assume that the sample size is equal for both groups, then the formula to calculate the degrees of freedom for a t-test for dependent means is:

df = n - 1

Where "n" is the number of pairs of observations in the sample.

Therefore, if the degree of freedom is 24, then the number of pairs of observations in the sample would be:

Let's assume that Mr. and Mrs. Johnson bought x adult tickets and y children's tickets.

Since there are three children, we know that:

y = 3x

The total cost of the parents' tickets is 7x, and the total cost of the children's tickets is 4y. Substituting y = 3x, we get:

total cost of parents' tickets = 7x

total cost of children's tickets = 4(3x) = 12x

Therefore, the ratio of the total cost of the parents' tickets to the total cost of the children's tickets is:

(7x) / (12x) = 7/12

So the answer is 7/12, which cannot be simplified further. Therefore, the ratio is 7/12, which can be written in the form aib as 0+7/12i.

Answer: 7:6

The average discount that is obtained by spinning the spinner is 17.7%.

Let, the probability of landing on an even number is denoted by P(E) and the probability of landing on an odd number is denoted by P(O).

We have that the pointer lands on an even number 135 times out of 250 spins.

So, the probability that is of landing on an even number is:

P(E) = Number of times the pointer lands on an even number / Total number of spins

P(E) = 135 / 250

Since, we have the sum of probabilities of all possible outcomes must be 1, we can find the probability of landing on an odd number as follows:

P(O) = 1 - P(E)

P(O) = 1 - (135 / 250)

Now, we know that even numbers get 20% off, and odd numbers get 15% off.

We find the average discount considering these probabilities:

Average Discount = (P(E) * 20%) + (P(O) * 15%)

Average Discount = (135 / 250) * 20% + [1 - (135 / 250)] * 15%

Now, let's perform the calculations:

Average Discount = (135 / 250) * 0.20 + [1 - (135 / 250)] * 0.15

Average Discount = 0.108 + (1 - 0.54) * 0.15

Average Discount = 0.108 + 0.46 * 0.15

Average Discount = 0.108 + 0.069

Average Discount = 0.177

A value of 0.25 for p(1-p) in the sample size formula when the true value of p is unknown.

This is because the value of p(1-p) is maximum when p=0.5, and since we do not have any information about the true value of p, assuming p=0.5 is the most conservative approach. Therefore, to calculate the sample size required to estimate a proportion using a confidence interval with a margin of error e, we can use the formula:

[tex]n = [z^2 * p(1-p)] / e^2[/tex]

where z is the z-score corresponding to the desired level of confidence (e.g., 1.96 for 95% confidence), and e is the desired margin of error. We can use p=0.5 and solve for n to get a conservative estimate of the sample size required for the given confidence level and margin of error.

To calculate the sample size formula for estimating a proportion using a confidence interval with a margin of error e, we

Since the product p(1-p) is not known, a conservative approach is to use p = 0.5, which is the value that maximizes the

L + 2W = 35

The area of the land is 132 square meters, which we can use to create another equation:

LW = 132

We can solve the first equation for L:

L = 35 - 2W

Substituting this into the second equation, we get:

(35 - 2W)W = 132

Expanding and rearranging, we get a quadratic equation:

2W^2 - 35W + 132 = 0

We can solve for W using the quadratic formula:

W = [35 ± √(35^2 - 4(2)(132))] / (2(2))

W = [35 ± √(841)] / 4

W = [35 ± 29] / 4

Solving for W, we get two possible values:

W = 4 or W = 15.5

If W is 4 meters, then L is:

The probability of winning at least once when playing the instant lottery twice is 0.19, or 19%.

To find the probability of winning at least once in the instant lottery when playing twice, we can use the complement rule.

The complement rule states that the probability of an event occurring (in this case, winning at least once) is equal to 1 minus the probability of the event not occurring (in this case, not winning both times).
Determine the probability of not winning in a single game, which is 1 - 0.1 = 0.9.
Calculate the probability of not winning both times, since outcomes are independent, by multiplying the probabilities of not winning each time: 0.9 * 0.9 = 0.81.
Finally, find the probability of winning at least once by subtracting the probability of not winning both times from 1: 1 - 0.81 = 0.19.
