<span>The z for $38.60 = (38.60 - 45)/16 = -0.4
</span>
<span>The percent of area associated with $38.60 = P(z < -0.4) = 0.34458 =34.46%
</span>
<span>The z for $57.80 = (57.8 - 45)/16 = 0.8.
</span>
<span>The percent of area associated with $57.80 = P(z < 0.8) = 0.78814 = 78.81%
</span><span>the percent of his expenses between $38.60 and $57.80 is (78.81 - 34.46) = 44.35%</span>

Answer:</h2>
(a)
(b)
(c)
<h2>
Step-by-step explanation:</h2>
We are given a function f(x) as :

(a)

We will substitute (x+h) in place of x in the function f(x) as follows:

(b)
Now on subtracting the f(x+h) obtained in part (a) with the function f(x) we have:

(c)
In this part we will divide the numerator expression which is obtained in part (b) by h to get:
The quadratic formula is -b + or - the square root of b squared - 4 times the a value and c value over 2a. So the roots would be -1.354249 and -6.645751. I believe these are the roots.
