Not sure if this is correct but:

Step-by-step explanation: P = 2000

R = 5% = 0.05

n = 4

y = 2000 ( 1 + $\frac{0.05}{4}$ ) $^{4t}$ = 2000 ( 1.0125 )

Substitute values in the compound interest formula:

y = P ( 1 + $\frac{r}{n}$ ) $^{nt}$ .

Hope this helps..

Assessment items What is the quotient? 1 5/8 ÷(−1 3/5 )

Solnce55 [7]

We need convert the mixed numbers to improper fractions.

$1\dfrac{5}{8}=\dfrac{1\cdot8+5}{8}=\dfrac{8+5}{8}=\dfrac{13}{8}\\\\1\dfrac{3}{5}=\dfrac{1\cdot5+3}{5}=\dfrac{5+3}{5}=\dfrac{8}{5}$

Divide the number by a fraction, this is the same as multiply this number by the reciprocal of the fraction:

$1\dfrac{5}{8}\div\left(-1\dfrac{3}{5}\right)=-\dfrac{13}{8}\div\dfrac{8}{5}=-\dfrac{13}{8}\cdot\dfrac{5}{8}=-\dfrac{(13)(5)}{(8)(8)}=-\dfrac{65}{64}\\\\\boxed{1\dfrac{5}{8}\div\left(-1\dfrac{3}{5}\right)=-1\dfrac{1}{64}}$

A corporation with several thousand employees wants to estimate the mean commute time for all employees. They would like to cons

velikii [3]

Answer:

C.25

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1-0.95}{2} = 0.025$

Now, we have to find z in the Ztable as such z has a pvalue of $1-\alpha$ .

So it is z with a pvalue of $1-0.025 = 0.975$ , so $z = 1.96$

Now, find the margin of error M as such

$M = z*\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

Which of the following is the smallest sample the company can take to achieve the desired margin or error?

This is n when $\sigma = 10, M = 4$

$M = z*\frac{\sigma}{\sqrt{n}}$

$4 = 1.96*\frac{10}{\sqrt{n}}$

$4\sqrt{n} = 1.96*10$

$\sqrt{n} = \frac{1.96*10}{4}$

$(\sqrt{n})^{2} = (\frac{1.96*10}{4})^{2}$

$n = 24.01$

We have to round up.

So the correct answer is:

C.25
