Answer:
<h2>Your Answer is C!!!!!!!!!</h2>Steps:
Add 2y to both sides:
Simplify:
Multiply both sides by 2:
2··6+2·2y
Simplify:
x>-12+4y
I really want to know what 2+2 is.

The function that is a tangent to the graph of f is
The definite integral can be interpreted as the resulting area of a region. In addition, it is a value in its result, that is, it does not depend on the variable x, which can be exchanged for any other variable without changing the value of the integral.
Knowing that :
- 40x + y = 0 is tangent of f(x)
- slope of the line = -40
therefore, f'(x)|x=a = -40, so only look for a we have:
if, x = -2, then y = 80 (since, 40x + y = 0), therefore, f(x) passes through (-2,80), so in the equation:
Therefore,

Answer:
(a)P(x>85.55)=0.02275
(b)
Step-by-step explanation:
We are given that
Average sales for an online textbook distributor per customer per purchase
,$67.63
Standard deviation of the amount spent on textbooks,$8.96
(a) We have to find probability for a randomly selected customer spent more than $85.55 per purchase.
=
=
=
P(x>85.55)=0.02275
(b)We have to find probability for a randomly selected customer spent less than $76.59 per purchase
