Answer:
A gasoline tank for a certain car is designed to hold 14.0 gal of gas.


a)What is the probability that a randomly selected tank will hold at most 13.7 gal?
We are supposed to find 



Refer the z table for p value
p value = 0.0668
So, 
The probability that a randomly selected tank will hold at most 13.7 gal is 0.0668
b)What is the probability that a randomly selected tank will hold between 13.4 and 14.3 gal?
We are supposed to find 



P(x<13.4)=P(z<-3)= 0.0013



P(x<14.3)= 0.9332

The probability that a randomly selected tank will hold between 13.4 and 14.3 gal is 0.9319
(c) If two such tanks are independently selected, what is the probability that both hold at most 14 gal?
We are supposed to find 



Refer the z table for p value
p value = 0.5
So, 
Two such tanks are independently selected, the probability that both hold at most 14 gal = 0.5 * 0.5 = 0.25
Hence If two such tanks are independently selected, the probability that both hold at most 14 gal is 0.25
Answer:
D. -20 + 35c
Step-by-step explanation:
<em><u>All you need to do is distribute the -5 to what's inside the parenthesis:</u></em>
-5(4 - 7c)
<em><u>The -5 can be distributed to the 4 and the -7c:</u></em>
-20 + 35c
Answer:
3 + 5x = 4x - 6
Let's do it quickly and simply,
Let's gather the like terms
5x - 4x = -6 - 3
x = - 9
