Answer:
(-5,-13)
Step-by-step explanation:
Find the vertex of the parabola y=1/5x^2+2x−8.
In this equation a=15 and b = 2.
x= -2/2(1/5) = -2/2/5 = -2/1 * 5/2 = -5
Substitute −5 into the equation y=1/5x^2+2x−8
y=1/5(−5)^2+2(−5)−8
y=5−10−8
y=−13
The vertex is (−5 , −13)
Since there is a 95% chance that you get two printers right, then you simply square the decimal equivalent which is .95 (Hence, you do .95^2). You will get .9025 (or 90.25%).
For letter b, you simply subtract .9025 from 1.
ans = 1-.9025
ans = .0975 (or 9.75%)
So the answer to B) would be there is a 9.75% chance the probability of a shipment can be rejected.
For this case we have the following functions:

We have to:
is given by:

Thus, the correct option is the option is A.
On the other hand,

Thus, the correct option is the option is A.
We also have:

Thus, the correct option is the option is B.
Last we have:

Thus, the correct option is the option is C.
ANswer:
Option A, A, B, C
Therefore
