Calculate the amount of money you'll have at the end of the indicated time period.

Shalnov [3]

The amount of money you'll have at the end of 10 years is $3900.

Given that, P=$3000, R=3% and T=10 years.

<h3>What is the formula to find the simple interest?</h3>

The formula to find the simple interest is $Interest=\frac{P \times T \times R}{100}$ .

Now, simple interest $=\frac{3000 \times 10 \times 3}{100}=\$900$ .

Amount=Simple Interest+Principal

=900+3000=$3900

Therefore, the amount of money you'll have at the end of 10 years is $3900.

Consider a normal distribution curve where the middle 85 % of the area under the curve lies above the interval ( 8 , 14 ). Use t

NeTakaya

Answer:

$\mu = 11$

$\sigma = 2.08$

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Middle 85%.

Values of X when Z has a pvalue of 0.5 - 0.85/2 = 0.075 to 0.5 + 0.85/2 = 0.925

Above the interval (8,14)

This means that when Z has a pvalue of 0.075, X = 8. So when $Z = -1.44, X = 8$ . So

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

$-1.44 = \frac{8 - \mu}{\sigma}$

$8 - \mu = -1.44\sigma$

$\mu = 8 + 1.44\sigma$

Also, when X = 14, Z has a pvalue of 0.925, so when $X = 8, Z = 1.44$

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

$1.44 = \frac{14 - \mu}{\sigma}$

$14 - \mu = 1.44\sigma$

$1.44\sigma = 14 - \mu$

Replacing in the first equation

$\mu = 8 + 1.44\sigma$

$\mu = 8 + 14 - \mu$

$2\mu = 22$

$\mu = \frac{22}{2}$

$\mu = 11$

Standard deviation:

$1.44\sigma = 14 - \mu$

$1.44\sigma = 14 - 11$

$\sigma = \frac{3}{1.44}$

$\sigma = 2.08$

What is the slope of a line that is perpendicular to the line y = 1?

Viktor [21]

Y = 1

Using y = mx + c.

Compare to y = 1, y = 0x + 1 ,

We can see that the slope m = 0 and the vertical intercept, c = 1.

For the line perpendicular to y = 1

Condition for perpendicularity m₁m₂ = -1

m₁ = 0, m₂ = ?

0*m₂ = -1

m₂ = -1/0 = Negative Infinite or Infinite

Slope of line perpendicular to y = 1, is = Infinite.
