I found this as an example from research. I do hope this helps. I have trouble in the same subject or I used to anyway. I hope this is what you were looking for. :)</span></span>
Answer:
Option B) The area to the right of 35.5
Step-by-step explanation:
Data:
Let the probability of the correct answers be denoted by the letter C.
The probability of no more than 35 defective CD's can be 35 or less. Therefore, it is presented as follows:
P ≤ 35
Let, the probability of more than 44 correct answers can be presented like this:
P > 44
Therefore, combining the two inequalities gives an area at the right of 35.5
Sub x^2+12x+10 for y in other equaiton
-8x+x^2+12x+10=10
x^2+4x+10=10
minus 10 both sides
x^2+4x=0
factor
(x+4)(x)=0
set to zer
x+4=0
x=-4
x=0
x=-4 or 0
sub back
y=0^2+12(0)+10, y=10
(0,10)
y=(-4)^2+12(-4)+10, y=-22
(-4,-22)
solutions are
(0,10) and (-4,-22)
