Three shipping companies want to compare the mean numbers of deliveries their drivers complete in a day.
The first two shipping companies provided their data from a sample of drivers in a table.

Company C showed its data in a dot plot.


Answer the questions to compare the mean number of deliveries for the three companies.

1. How many drivers did company C use in its sample?

2. What is the MAD for company C's data? Show your work.

3. Which company had the greatest mean number of deliveries?

4. Compare the means for companies A and B. By how many times the MAD do their means differ? Show your work.

Answers

Answer:

1. the company C used 10 drivers2.      6 + 7 + 8 + 9 + 10 + 10 + 10 + 12 + 14 + 14 = 100/10. The Mean = 10  (6- 10) + (7- 10) + (8- 10) + (9- 10) + (10- 10) + (10- 10) + (10- 10) + (12- 10) + (14- 10)4 + 3 + 2 + 1 + 0 + 0 + 0 + 2 + 4  = 16/10 = 1 6/103. The groups that had the most deliveries where group A and B4. So if there are 6 deliveries of group A and 14 deliveries from group B i think the MAD would be 4

Step-by-step explanation:

The mean absolute deviation of company C's data is 2.

What is a dot plot?

A dot plot, also known as a strip plot or dot chart, is a simple form of data visualization that consists of data points plotted as dots on a graph with an x- and y-axis. These types of charts are used to graphically depict certain data trends or groupings.

The mean absolute deviation (MAD) is the mean distance between each data value and the mean of the data set.

Number of drivers used by company C in its sample = 10

Mean absolute deviation for company C's data = 2

Company B has the greatest mean number of deliveries.

The mean deliveries of company B is 4 times MAD of company A.

We are given the sum of each point from the mean. It is 20.

Mean absolute deviation of company C  = 20/10 = 2.

Mean A = 6

Mean B = 14

Mean B - Mean A = 8 = 4×2 = 4 times MAD (since MAD =2 for both companies).

Therefore, the mean absolute deviation of company C's data is 2.

The slope of the graph of a direct variation function is -3. Which of the following is true?


The function is linear.
The equation is y = -3 x .
The point (2, -6) is on the graph of the function.
The equation of the function is y = - 1/3 x
REMEMBER THIS IS A SELECT ALL

Answers

i believe it’s B and C

The statement which is true for the function having slope is that the function is linear.

What is function?

Function is like a defined relationship between two or more variables expressed in equal to form. In a function each value of x must has a corresponding y value. The value which is entered in the function is known as domain and the value which comes out after is codomain of the function.

How to find function?

We have been given that slope of function is -3.

1) The function is linear because slope is in single number.

2) We cannot say that the equation is y=-3x because it depends on other points also. Suppose the point at which the line passes is (1,2)

y-2=-3(x-1)

y-2=-3x+3

y=-3x+3+2

y=-3x+5

So  this statement is wrong,

3) Same in statement third , we cannot say that the point (2,-6) lie on line.

4) It is wrong because in the given option slope is -1/3.

Hence the correct statement is that the function is linear.

Find the annual interest rate.

I= $164.50, P= $940, t= 2.5 years

___%

Answers

Answer:

250.35

Step-by-step explanation:

The interest rate is about 7% per year.

What is simple interest?

Simple interest is the amount of interest charged on a specific principal amount at a specific interest rate. Compound interest, on the other hand, is the interest that is computed using both the principal and the interest that has accumulated over the preceding period.

We can use the formula for simple interest to find the annual interest rate:

I = P * r * t

where I is the interest, P is the principal (the amount borrowed or invested), r is the annual interest rate as a decimal, and t is the time in years.

Plugging in the given values, we have:

164.50 = 940 * r * 2.5

Dividing both sides by 940 * 2.5, we get:

r = 164.50 / (940 * 2.5)

r ≈ 0.07

Multiplying by 100 to convert to a percentage, we get:

r ≈ 7%

Therefore, the annual interest rate is approximately 7%.
