A = $4,312.00

I = A - P = $2,112.00

Hey!

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 8%/100 = 0.08 per year.

Solving our equation:

A = 2200(1 + (0.08 × 12)) = 4312

A = $4,312.00

The total amount accrued, principal plus interest, from simple interest on a principal of $2,200.00 at a rate of 8% per year for 12 years is $4,312.00.

The scores on a standardized exam are normally distributed with a mean of 400 and a standard deviation of 50.

S_A_V [24]

Using the normal distribution, it is found that approximately 40% of the scores are greater than 413.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

$Z = \frac{X - \mu}{\sigma}$

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

In this problem, we have that the mean and the standard deviation of the scores are given by:

$\mu = 400, \sigma = 50$

Approximately 40% of the scores are greater than the 60th percentile, which is <u>X when Z = 0.253</u>.

Then:

$Z = \frac{X - \mu}{\sigma}$

$0.253 = \frac{X - 400}{50}$

X - 400 = 50(0.253)

X = 412.65.

Rounding up, approximately 40% of the scores are greater than 413.
