To start off with, I would draw a dotted line to form a rectangle and a square. Then you find the area of the square and the rectangle, and you and them together. Remember area is length times width.

Another way to solve this is draw a line from the 9 long side up and from the 6 long side out. This creates a full rectangle with out any where shapes. Find the area of the rectangle you created by drawing the lines, and subtract it from the area of the whole rectangle.

HOPE THIS HELPS!

Using the z-distribution, it is found that the 90% confidence interval is given by: (0.6350, 0.6984).

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which:

$\pi$ is the sample proportion.

z is the critical value.

n is the sample size.

In this problem, we have a 90% confidence level, hence $\alpha = 0.9$ , z is the value of Z that has a p-value of $\frac{1+0.9}{2} = 0.95$ , so the critical value is z = 1.645.

The sample size and the estimate are given by:

$n = 600, \pi = \frac{400}{600} = 0.6667$

Hence, the bounds of the interval are given by:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6667 - 1.645\sqrt{\frac{0.6667(0.3333)}{600}} = 0.6350$

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6667 + 1.645\sqrt{\frac{0.6667(0.3333)}{600}} = 0.6984$

The 90% confidence interval is given by: (0.6350, 0.6984).

mars1129 [50]

Answer:

3095.6 ft³

Step-by-step explanation:

Volume cone = 1/3(πr²h)

= 1/3(π(13.9)²(15.3))

= 1/3(π(193.21)(15.3))

= 1/3(2956.113π)

= 985.371π ≈ 3095.6 ft³
