Answers
Answer:
Median:38 Mean:48 Range:44
Step-by-step explanation:
To find the median we have to put them in order: 32, 33, 38, 61, 76. The middle one is 38 so 38 is the median. The mean would be them added up together, which would be 240. There are 5 numbers, so we do 240/5=48. The range is 76-32=44.

what is the long method of 23 ÷ 650
Answers
Answer: The long division method is a way to solve division problems by hand. Here are the steps to do long division:
Write the dividend (the number being divided) inside a long division bracket, and write the divisor (the number doing the dividing) outside of the bracket.
Divide the first digit of the dividend by the divisor. Write the answer (the quotient) above the dividend, and write any remainder (what’s left over) below the first digit of the dividend.
Bring down the next digit of the dividend next to the remainder.
Repeat step 2 until you’ve brought down all of the digits of the dividend.
The final answer is your quotient with any remainder written as a fraction.
Suppose you want to have the same number of T-shirts as polo shirts. Buying 200 shirts with a budget of 5400 , how many of each shirt should you buy?
Answers
100 T-shirts and 100 polo shirts should be bought with the budget of 5400.
Let the price of a T-shirt be t.
Let the price of a polo shirt be p.
The following equation represents the given information:
p = t
We need to find the number of each shirt to buy.
Let the number of T-shirts bought be x.
The number of polo shirts bought is also x.
Combining the number of T-shirts and polo shirts bought gives the total number of shirts:
x + x = 2x
We have a budget of $5400.
We can set up an equation that relates the budget and the number of shirts bought.
The equation is: 200t + 200p = 5400
We substitute p = t into the equation above and simplify.
200t + 200(t) = 5400400t
= 5400t
= 13.5
We now know the price of a T-shirt. We can use the information to find the number of each shirt bought.
200t = 200(13.5) = 2700
The total number of shirts bought is 200. We want to divide the shirts equally between T-shirts and polo shirts.
x = 100
The number of each shirt to buy is 100.
Therefore, 100 T-shirts and 100 polo shirts should be bought.

In this particular case, the research question is related to a Star Trek scenario, where two groups of people have different levels of experience with the franchise.
The most appropriate statistical procedure to answer this research question would be a two-sample t-test for means.
This is because the two-sample t-test for means is used when two independent samples are compared to determine if there is a significant difference between the means of the two samples.
This is useful in this scenario, as it will allow us to compare the levels of experience between the two groups and determine if there is a statistically significant difference between them.

A company director investigated whether there is a difference in the mean number of overtime hours worked each week by employees assigned to two different managers. Each manager, A and B, manages 100 employees. Random samples of 35 employees from manager A and 40 employees from manager B were selected. The number of overtime hours worked was recorded for the 75 employees each week. Have the conditions been met for inference with a confidence interval for the difference in the population means?
A Yes, all conditions have been met.
B No, because the data were not collected using a random method.
C No, because the size of at least one of the samples is greater than 10 percent of the population.
D No, because the sample sizes are not large enough to assume the distribution of the difference in sample means is normal.
E No, because the sample sizes are not the same.
Answers
The answer is D. No, because the sample sizes are not large enough to assume the distribution of the difference in sample means is normal.
Determine sample mean?In order to perform inference with a confidence interval for the difference in population means, certain conditions need to be met. One of the conditions is that the sample sizes should be sufficiently large.
For the distribution of the difference in sample means to be approximately normal, both sample sizes should ideally be large, typically with a guideline of at least 30 observations. In this case, the sample sizes are 35 for manager A and 40 for manager B, which are relatively small compared to the guideline.
Therefore, (D) the condition of having large enough sample sizes to assume a normal distribution for the difference in sample means is not met. As a result, the conditions for inference with a confidence interval for the difference in population means have not been met.

Answers
The probability that abby, barry, and sylvia win the 1st, 2nd, 3rd prizes resprctively, in a drawing of 200 people in contest that no one win the prize is equals to 0.0000001269.
Total number of people present= 200
so, total possible outcomes= 200
We have to determine the probability that abby, barry, and sylvia win the 1st, 2nd, 3rd prizes resprctively.
The number of favourable outcomes for winning first prize = 1
So, probability that abby win the first prize = \(\frac{1}{200} \)
The number of favourable outcomes for winning second prize = 1
So, probability that barry win the second prize = \(\frac{1}{199} \)
The number of favourable outcomes for winning third prize = 1
So, probability that sylvia win the third prize = \(\frac{1}{198} \)
Now, total probability that no one can win more than one prize = \(\frac{1}{200} × \frac{1}{199} × \frac{1}{198} \)
= 0.0000001269
Hence, required probability value is 0.0000001269.

the first of a series of usually four downs in which a football team must net a 10-yard gain to retain possession of the ball.
If the team with the ball can pick up one yard or more on the third-down play, then they will be given a first down, which means they get to start all over with a new set of four downs. A team can continue moving the football down the field as long as they continue to pick up first downs.

Abigail redecorates her house. a scale drawing of her house shows the dimensions of the house as
9 cm by 10 cm. if 6 cmn on the scale drawing equals 12 ft, what are the actual dimensions of abigail's
house?
Answers
The actual dimensions of Abigail's house are 18 ft by 20 ft.
Abigail's house is represented by a scale drawing with dimensions of 9 cm by 10 cm. We are told that 6 cm on the scale drawing equals 12 ft. To find the actual dimensions of Abigail's house, we need to determine the scale factor.
First, we calculate the scale factor by dividing the actual length (12 ft) by the corresponding length on the scale drawing (6 cm). The scale factor is 12 ft / 6 cm = 2 ft/cm.
Next, we can use the scale factor to find the actual dimensions of Abigail's house. We multiply each dimension on the scale drawing by the scale factor.
The actual length of Abigail's house is 9 cm * 2 ft/cm = 18 ft.
The actual width of Abigail's house is 10 cm * 2 ft/cm = 20 ft.
Therefore, the actual dimensions of Abigail's house are 18 ft by 20 ft.
