B, because it is the one that is closest together, and it is like a upside down V, unlike Graph A, which is spread out so much.
8(v−4)+7v=−2
(8)(v)+(8)(−4)+7v=−2
8v+−32+7v=−2
(8v+7v)+(−32)=−2
15v+−32=−2
15v−32=−2
Add 32 to both sides.
15v−32+32=−2+32
15v=30
Divide both sides by 15.
15v/15=30/15
v = 2
Answer:
0.3085,0.2417,0.0045
Step-by-step explanation:
Given that X, the amount of money spent at shopping centers between 4 P.M. and 6 P.M. on Sundays has a normal distribution with mean $85 and with a standard deviation of $20.
X is N(85, 20)
To convert into std normal variate we use the following formula

a) the probability that he has spent more than $95 at the mall
=
b. the probability that he has spent between $95 and $115 at the mall
=
c. If two shoppers are randomly selected, what is the probability that both shoppers have spent more than $115 at the mall
=product of two probabilities since independent
=
