No because 9/1,000 in decimals would be 0.009 because if the number was a 3 number then it would go in the tenths

Given:

Width of rectangular prism = 20 ft

height of rectangular prism = 12 ft

Length of rectangular prism = 45 ft

Cylindrical diameter = 20 ft

To find:

Volume of the tent

Solution:

Volume of the rectangular prism = length × width × height

                                                       = 45 × 20 × 12

Volume of the rectangular prism = 10800 ft³

Radius of cylinder = 20 ÷ 2 = 10 ft

Height of cylinder = length of rectangular prism

Volume of cylinder = \pi r^{2} h

Volume of half cylinder = \frac{1}{2} \pi r^2h

                                      $=\frac{1}{2} \times 3.142\times 10^2 \times45

Volume of half cylinder = 7069.5 ft³

Volume of tent = volume of rectangular prism + volume of half cylinder

                         = 10800 ft³ + 7069.5 ft³

                         = 17869.5 ft³

                         = 17869 ft³ (nearest cubic foot)

The volume of the tent is 17869 cubic feet.

Answer:

b. The margin of error would decrease.

Step-by-step explanation:

Margin of error of a confidence interval:

The margin of error of a confidence interval has the following format:

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

In which z is related to the confidence level, \sigma is the standard deviation of the population and n is the size of the sample.

This means that the margin of error is inversely proportional to the size of the sample, which means that if the sample size increases, the margin of error decreases.

In this question, the sample size is increased, leading to a smaller margin of error. So the correct answer is given by option b.

Which matrix represents the system of equations shown below 2x=13 and 3x-2y=11​
makkiz [27]

Answer:

A. Matrix A

Step-by-step explanation:

When you put a systems of linear equations in matrix form, you take only the coefficients of the <em>xy </em>terms and sort them. <em>x</em> goes first, <em>y</em> comes after, and the numbers after the bars are the constants.
