Find

R(V)

p(x)×x
x(-3/2x+112)
-3/2x²+112x

Now

y=-3/2x²+112x

Find vertex x coordinate

-b/2a
-112/-2(-3/2)
-37.3

Put in equation

y=-3/2(-37.3)²+112(-37.3)
y=-2086.9-84+4177.6
y=$6264.6
y=$62.64M

As a is negative parabola is facing downwards hence vertex is minimum .

So minimum value is $62M which is far more than given .

Aaron made a $400 purchase using his credit card. The credit card has a simple interest rate of 12% each year. How much will Aar

melisa1 [442]

Answer: 448 dollars

=============================================

Work Shown:

P = 400 is the balance

r = 0.12 is the decimal form of the interest rate

t = 1 is the number of years

Use those values to get the simple interest to be

i = P*r*t

i = 400*0.12*1

i = 48

The amount of interest charged is $48

Add this onto the balance of 400 dollars and the total amount Aaron owes is P+i = 400+48 = 448 dollars.

The distribution of heights for adult men in a certain population is approximately normal with mean 70 inches and standard devia

KengaRu [80]

Answer:

The interval (meassured in Inches) that represent the middle 80% of the heights is [64.88, 75.12]

Step-by-step explanation:

I beleive those options corresponds to another question, i will ignore them. We want to know an interval in which the probability that a height falls there is 0.8.

In such interval, the probability that a value is higher than the right end of the interval is (1-0.8)/2 = 0.1

If X is the distribuition of heights, then we want z such that P(X > z) = 0.1. We will take W, the standarization of X, wth distribution N(0,1)

$W = \frac{X-\mu}{\sigma} = \frac{X-70}{4}$

The values of the cumulative distribution function of W, denoted by $\phi$ , can be found in the attached file. Lets call $y = \frac{z-70}{4}$ . We have
