How much would you make for one month (4 weeks) if you worked a 40 hour week?

Anon25 [30]

Answer:

Unclear

Step-by-step explanation:

I believe we need more information to solve the problem!

We currently have:

a = b

b = total amount for 40 hours

As you can see, we cannot solve this. For a we would need something like how much you make per week, etc!

Answer:

her salary after 8 years is $26,602

Step-by-step explanation:

Given that

Fiona salary is $21,000

She received 3% raise each year

We need to find her salary after 8 years

So, here we apply the future value formula

i.e.

= Present value × (1 + rate of interest)^number of years

= $21,000 × (1 + 0.03)^8

= $21,000 × 1.03^8

= $26,602

hence, her salary after 8 years is $26,602

A survey of 80 randomly selected companies asked them to report the annual income of their presidents. Assuming that incomes are

Artyom0805 [142]

Answer:

The 90% confidence interval estimate of the mean annual income of all company presidents is ($579,545, $590,580).

Step-by-step explanation:

The information provided is:

$n=80\\\sigma=30,000\\\bar x=585062.50\\\text{Confidence level} = 90\%$

The critical value of <em>z</em> for 90% confidence level is, 1.645.

Compute the 90% confidence interval estimate of the mean annual income of all company presidents as follows:

$CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}\\\\=585062.50\pm 1.645\times\frac{30000}{\sqrt{80}}\\\\=585062.50\pm5517.50\\\\=(579545, 590580)$

Thus, the 90% confidence interval estimate of the mean annual income of all company presidents is ($579,545, $590,580).

This interval implies that there is 90% probability that the true mean annual income of all company presidents is within this interval.
