I’m studying for my Sat later in the month, and even using the answer key I don’t understand how to solve this question. Help?
shepuryov [24]

So with this equation, since the volume of the cylinder is 96 pi, plug that into the V variable, and since the radius of one of the marbles is 3, plug that into the r variable. From here, we can solve for x: 96\pi =24\pi +x(\frac{4}{3}\pi*3^3)

Firstly, solve the parentheses: 96\pi =24\pi +x(\frac{4}{3}\pi*27)\\ 96\pi =24\pi +x(36\pi)

Next, multiply 36 pi and x: 96\pi = 24\pi +36\pi x

Next, subtract 24 pi on both sides: 72\pi =36\pi x

Lastly, divide both sides by 36 pi, and your answer will be 2=x, or B.

Clothing sizes are not standardized across brands. Suppose that a large study of women's size 14 jeans revealed that the mean hi
kenny6666 [7]

Using the z-distribution, we have that:

  • The mean hip measurement for the random sample of 15 pairs of women's size 16 jeans is of 44.1 inches.
  • The <u>margin of error</u> is of 0.8 in.
  • The interpretation is: Mallorie is 99% sure that the mean hip measurement of size 16 jeans is between 43.3 in and 44.9 in.

The first step to solve this question, before building the confidence interval, is finding the sample mean, which is the <u>sum of all observations divided by the number of observations</u>. Hence:

\overline{x} = \frac{44.5+43.0+46.6+42.9+43.7+43.9+42.4+43.2+43.1+44.4+46.1+44.7+44.4+43.9+44.7}{15} = 44.1

The margin of error of a z-confidence interval is given by:

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

In which:

  • z is the critical value.
  • \sigma is the population standard deviation.
  • n is the sample size.

We have to find the critical value, which is z with a p-value of \frac{1 + \alpha}{2}, in which \alpha is the confidence level.

In this problem, \alpha = 0.99, thus, z with a p-value of \frac{1 + 0.99}{2} = 0.995, which means that it is z = 2.575.

Then, the margin of error is:

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

M = 2.575\frac{1.2}{\sqrt{15}}

M = 0.8

The <u>margin of error</u> is of 0.8 in.

The interval is:

\overline{x} \pm M

\overline{x} - M = 44.1 - 0.8 = 43.3

\overline{x} + M = 44.1 + 0.8 = 44.9

The interpretation is:

Mallorie is 99% sure that the mean hip measurement of size 16 jeans is between 43.3 in and 44.9 in.
