Answer:

The correct answer is Pete saves $2.10 by buying bulbs in packages of 3 for $6.39 each.

Step-by-step explanation:

Pete can buy daffodil bulbs in packages of 3 for $6.39 or in packages of 2 for $4.40.

He needs to buy 30 bulbs at a better price.

Money spent by buying bulbs in packs of 3 = 10 × 6.39 = $63.90.

Money spent by buying bulbs in packs of 2 = 15 × 4.40 = $66.

Money saved if bought in packs of 3 = 66 - 63.90 = $ 2.10.

Thus Pete should buy 30 daffodil bulbs in packages of 3 and save $2.10.

Answer:

838.08 in³

Step-by-step explanation:

volume of tank = (36×24×24)+(½×3.14×12²×24)

= 20,736 + 5,425.92

= 26,161.92 in³

the remaining water = 27,000 - 26,161.92

= 838.08 in³

4)In order to set rates, an insurance company is trying to estimate the number of sick daysthat full time workers at an auto rep
bagirrra123 [75]

Answer:

A sample of 18 is required.

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 - 0.92}{2} = 0.04

Now, we have to find z in the Z-table as such z has a p-value of 1 - \alpha.

That is z with a pvalue of 1 - 0.04 = 0.96, so Z = 1.88.

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.

A previous study indicated that the standard deviation was 2.2 days.

This means that \sigma = 2.2

How large a sample must be selected if the company wants to be 92% confident that the true mean differs from the sample mean by no more than 1 day?

This is n for which M = 1. So

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

1 = 1.88\frac{2.2}{\sqrt{n}}

\sqrt{n} = 1.88*2.2

(\sqrt{n})^2 = (1.88*2.2)^2

n = 17.1

Rounding up:

A sample of 18 is required.
