Answer:

x = 10 and x = -2

Step-by-step explanation:

The equation has 2 solutions because we have a square. When things are squares, we get a positive and negative solution.

(x-4)^2 - 28 = 8

Add 28 to each side

(x-4)^2 - 28+28 = 8+28

(x-4)^2 = 36

Take the square root of each side

sqrt((x-4)^2) = ±sqrt(36)

x-4 = ±6

Add 4 to each side

x-4+4 = 4 ±6

x = 4 ±6

x = 4+6 and x = 4-6

x = 10 and x = -2

Bob is thinking about leasing a car. the lease comes with an interest rate of 8%. determine the money factor that will be used t

alukav5142 [94]

The money factor that will be used to calculate Bob's payment is 0.00333 if the annual percentage rate is 8% option (c) is correct.

<h3>What is money factor?</h3>

It is defined as the ratio of the annual percentage rate to 2400. Usually, it can be used to calculating the financing costs of a lease with monthly installments.

Bob is thinking about leasing a car, the lease comes with an interest rate of 8%.

The annual percentage rate(APR) = 8%

We know the formula for finding the money factor is given by:

$\rm Money \ factor = \frac{APR}{2400}$

$\rm Money \ factor = \frac{8}{2400}$

Money factor = 0.00333

Thus, the money factor that will be used to calculate Bob's payment is 0.00333 if the annual percentage rate is 8% option (c) is correct.

Use the given information to construct a 99% confidence interval estimate of the mean of the population. n = 39, σ = 3.86, Xbar

horsena [70]

Answer:

40.1 < μ < 43.3

Step-by-step explanation:

Margin of error = critical value × standard error

ME = CV × SE

At 99% confidence and 38 degrees of freedom, CV = 2.712.

SE = s / √n

SE = 3.86 / √39

SE = 0.618

So the margin of error is:

ME = 2.712 × 0.618

ME = 1.7

So the 99% confidence interval of the population mean is:

μ = 41.7 ± 1.7

40.0 < μ < 43.4
