Answer:
Patricia = $47.5 ;
Greg = $57.5 ;
$10
Step-by-step explanation:
Perimeter of a rectangle : 2(l + b)
Patricia :
7ft * 12 ft
2(7 + 12) = 2(19) = 38 ft
Total fencing cost :
1.25 * 38 = $47.5 ft
Greg:
8ft by 15ft
2(8 + 15) = 2(23) = 46ft
Total fencing cost :
1.25 * 46 = $57.5
Difference in cost :
57.5 - 47.5 = $10
Answer: A Yes, because the balls are randomly selected, the distances of the new ball can be compared to the distances of the original ball.
B Yes, because the original ball type is included in this experiment, the distances the different balls travel can be accurately compared.
Step-by-step explanation:
C No, because a placebo ball was not used, a comparison cannot be made to determine if the new ball travels significantly farther.
D No, because all of the new type of balls are not hit first, the distances they travel cannot be compared to the distances of the original ball.
