D
Step-by-step explanation:
A is (-8,8) so you would divide each 8 by 4 because 8 divided by 1/4 so you will have (-2,2)
B is (-8,4) so divide the by 1/4 which would be (-2,1)
C is (4,-4) so divide that and and you get (1,-1)
Answer:
Step-by-step explanation:
-Amy walks a distance of 7/8 mile
-Tom walks a distance of 4/8 mile.

A. Two measurements(AandB)are taken on the same round.\oIs there a difference in the measurement of the muzzle velocity between device A and device B at the α=0.01 level of significance? Note: A normal probability plot and boxplot of the data indicate that the differences are approximately normally distributed with no outliers.
B. Construct a 99% confidence interval about the population mean difference. Compute the difference as device A minus device B. Interpret your results. The confidence interval is (__,__)?

Answer:
1152
Step-by-step explanation:
First we need to find the area of the wall in square inches
8 ft = 8*12 = 96 inch tall
36 ft = 36 * 12 = 432 inches wide
The area = 96 * 432 =41472 in^2
Each ounce of paint cover 72 in^2 so divide by 72
41472/72 =576
We need 576 ounces to cover the wall
At 2 dollars per ounces
576*2 =1152 dollars to paint the wall
