Use A as the subject of formula<br>p= A ( 1+r\100)

ZanzabumX [31]

Answer:

$A = \frac{100 P}{100+r}$

Step-by-step explanation:

Given $P = A( 1 + \frac{r}{100} )$

To make A as the subject of the formula we need to rearrange

Divide by $(1 +\frac{r}{100})$ throughout we get

$\frac{P}{1+\frac{r}{100}} = A$

$A = \frac{100P}{100 + r}$

The amounts of time employees of a telecommunications company have worked for the company are normally distributed with a mean o

Fynjy0 [20]

Answer:

a) 5.6 years

b) 0.4478

Step-by-step explanation:

We are given the following in the question:

Mean, μ = 5.6 years

Standard Deviation, σ = 1.9 years

Sample size, n = 18

We are given that the distribution of amounts of time is a bell shaped distribution that is a normal distribution.

a) Mean of each sample.

The best estimator of the sample mean is the population mean itself. Thus, we have:

$\mu_{x} = \mu = 5.6$

Thus, the sample mean is 5.6 years.

b) Standard error

Formula:

$S.E = \dfrac{\sigma}{\sqrt{n}}$

Putting values, we have.

$S.E = \dfrac{1.9}{\sqrt{18}} = 0.4478$

Thus, the standard error is 0.4478.
