Answer:

301.4 ft.

Step-by-step explanation:

The radius of this circle is 4; the height of this circle is 6.

Using the formula, πr²h, we can plug-in the unknown values.

In the formula, 'r' means radius, 'h' means height, 'π' means pi. 3.14 is often a substitute for pi.

πr²h - π4² · 6 = 301.44.

301.44 rounded to the nearest tenth is 301.4.

Therefore, the volume of this cylinder is 301.4 ft.

Answer:

The 99% confidence interval for the mean peak power after training is [299.4, 330.6]

$299.4\leq\mu\leq 330.6$

Step-by-step explanation:

We have to construct a 99% confidence interval for the mean.

A sample of n=7 males is taken. We know the sample mean = 315 watts and the sample standard deviation = 16 watts.

For a 99% confidence interval, the value of z is z=2.58.

We can calculate the confidence interval as:

$M-z\sigma/\sqrt{n}\leq\mu\leq M+z\sigma/\sqrt{n}\\\\315-2.58*16/\sqrt{7}\leq\mu\leq 315+2.58*16/\sqrt{7}\\\\315-15.6\leq \mu\leq 315+15.6\\\\299.4\leq\mu\leq 330.6$

The 99% confidence interval for the mean peak power after training is [299.4, 330.6]

Think it’s A just because it’s actually decaying rather than being from decayed to up like B, C, and D( I don’t know how to explain it, sorry) I’m not sure however !
