Answer:
Option D
Step-by-step explanation:
<h2>Distance between two points</h2>
The y-value of the two points is unchanged. So, the line is parralel to x-axis.
The distance will be the diffrence between the x-co ordinates.


(a)
12+0.72(8)
12+5.76
17.76 qts of antifreeze
(b)
100(12+8(.72))/(12+8)
100(12+5.76)/20
100(17.76)/20
5(17.76)
88.8%
A probability of 0.075 corresponds to a z-score of about

, i.e.
16/2 times 2 =16, 2/2 times 16 = 16
Answer:
V=pi x (r)^2 x h
V-volume r-radius h-height
V= pi x (3)^2 x 9
V= pi x 9 x 9
V= pi x 81
V= 254.47 (rounded)
