Which value is equivalent to (7x5x2/7x3)^2 x (5^0/2^-3)^3 x2^-9?
koban [17]

Answer:

100/9

Step-by-step explanation:

(7*5*2/7*3)² * (5^0/2^-3)³ * 2^-9

Solution:

We know that any number with power 0 = 1

(7*5*2/7*3)² * (1/2^-3)³ * 2^-9

Now cancel out 2 by 2

= (7*5*2/7*3)² * (1/1^-3)³ * 1^-9

=(70/21)² * (1)³/(1^-3)³ * 1^-9

=(10/3)^2 * 1/1^-1 * 1/1^9

=100/9 *1 *1

=100/9....

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
