2. A circular patio has a diameter of 18 feet. How

lisabon 2012 [21]

Answer: So to cover the patio it would take 255 whole tiles. 254.469 if you want to be exact.

Step-by-step explanation:

When finding flooring needed we are finding for area. We know the formula for finding the area of a circle is A= $\pi r^{2}$ so we plug in our known variables...

we know r because radius is half of diameter and diameter was given in problem. So half of 18 is 9.

r=9

A= $\pi 9^{2}$

A= $\pi$ 81

A=254.469

The following situation calls for a significance test. State the appropriate null hypothesis <img src="https://tex.z-dn.net/?f=H

harina [27]

Answer:

$H_{0}: \sigma = 10\\$

$H_{a}: \sigma > 10\\$

Step-by-step explanation:

We are given the following in the question:

The organizers estimate that the variation in distance flown by the athletes will be σ = 10 meters.

This will be stated by the null hypothesis.

$H_{0}: \sigma = 10\\$

It was claimed that the organizers are underestimating the variation and the variation in distance is greater than 10.

This will be stated by the alternate hypothesis.

$H_{a}: \sigma > 10\\$

The parameter for the given hypothesis is standard deviation, $\sigma$ .
