Answer:
8.8 cm
Step-by-step explanation:
-We know that the top 20% of the books are oversized.
-We therefore find the z-value of the top 20%:
#We substitute the z value in formula to solve X.
Where
- X is the minimum thickness of the book.
-Given 
, the minimum thickness,X can be calculated as follows:
Hence, the minimum thickness of the oversized books is 8.8 cm
Answer:
a. $15.00
b. $15.00
c. they earn the same. If you divide Carl's hours by the amount of time he works, for instance, 45÷3=15, you get 15 for all of them. They earn the same.
Answer:
the answer is 64
Step-by-step explanation:
Notice that we can simplify both numerator and denominator of our rational function. In the numerator we have a quadratic expression of the form
. To to simplify it, we are going to find tow numbers that add to 2 and multiply to -8; those numbers are 4 and -2.
In the denominator we have a difference of squares:
Now we can rewrite our function:
From the simplified form of our rational function we can infer that its graph has two vertical asymptotes at
and
We can conclude that the graphic of our rational function is:
