Answer:
Step-by-step explanation:
Given that the time to complete a standardized exam is approximately normal with a mean of 70 minutes and a standard deviation of 10 minutes.
P(completing exam before 1 hour)
= P(less than an hour) = P(X<60)
=P(Z<
)
=0.5-0.34=0.16
i.e. 16% of students completed the standardized exam.
<span>You take the probability of success (and the revenue generated by it) and the probability of failure (and the cost associated with trying it) and get an expected value:
aP(a) + bP(b)
I hope my answer has come to your help. God bless and have a nice day ahead!

Hi there!
Using some simple conversions we can determine how many quarts are in 2 & a half gallons.
1 gallon = 4 quarts.
2 gallons = 8 quarts.
Since we're trying to determine how many quarts are in 2 & a half gallons we can separate our problem into how many quarts are in two gallons and how many are in a half a gallon.
2 gallons = 8 quarts.
.5 gallon = 2 quarts.
After adding this together we come up with the answer that there are 10 quarts in 2 & a half gallons. :)
Answer:
First Question: x = -8
Step-by-step explanation:
-12x + 4 = 100
firstly we subtract 4 from 4 which will remove it from the equation and then we also subtract 4 from 100.
Now the equation will be -12x=96
Then we divide -12x by -12 to figure out the value of x and we also dive 96 by -12.
-12x/-12= 96/-12
Answer is x = -8
Hopefully that helped :)
