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:
The means differ by 4 times the MAD.
Step-by-step explanation:
I may be missing something, but this is how I interpret it.
The mean number of deliveries for company A is 6, and the mean for company B is 14. Lastly, the mean absolute deviation (MAD) for both companies is 2.
[tex]14-6=8\\8\div2=4[/tex]
The means differ by 8, and that is 4 times the MAD, so the means differ by 4 times the MAD.

Kevin is creating a target for a game that will be played at the school's carnival and needs to put red tape in the shape of an "x" as shown below. If the area of the square board is 25 square feet, how many feet of tape will he need?
Answers
Answer:Kevin need 14.14 feet of red tape
Step-by-step explanation:
Given: (Figure Attached)
Area of Square = 25 square feet
As we know
Area of square = length x width = a x a = 25
a * a = 25
a = ±5 by taking square root both sides
It means a = 5 as the length can not be negative
Now we know the length of sides of square and as shown in figure we can break the figure in two triangles,
By using Pythagoras theorem on one triangle we will find the length of one line of x and then multiply the x with 2 to get the overall feet of tape.
=
=
x = ± 7.07 It means x = 7.07
Now the total tape required is 2 * x = 2*7.07 = 14.14

We are given that:
variables x and y vary directly, this means that:
y = kx where k is the constant of proportionality
Now, we are also given that:
y = 45 at x = 40.
We will use these values and substitute in the above relation to get k as follows:
y = kx
45 = 40k
k = 45/40 = 9/8 = 1.125
Based on the above calculations, the equation that relates x and y is:
y = 1.125x

The price of an item has been reduced by 35%. The original price was $60. What is the price of the item now
Answers
Answer:
Step-by-step explanation:
$60=100%
A 35% reduction is the same as multiplying by 0.65(1-0.35).
$60*0.65=$39
100%=60
10%=6
(6x3) 30%=18
(6÷2)5%=3
(18+3)35%=21
60-21= $39
