300 dollars, 15x20 because they count any fraction as a foot, so is like you are going to buy 20 foot of carpet.

78% of all Millennials drink Starbucks coffee at least once a week. We speculate that this rate is lower among teenager in the U
Over [174]

According to the sample size, it will be necessary to approximate the data through the normal distribution and through this calculate the standard deviation to obtain both the average, the standard deviation and the obtained deviation. Here the sample size is 40.

Approximately the distribution of proportion is a Normal distribution using the CLT. the mean will be 0.78, then we have that the standard deviation is,

\sigma = \sqrt{\frac{p(1-p)}{n}}

\sigma = \sqrt{\frac{(0.78)(0.22)}{40}}

\sigma = 0.0655

Then the distribution will be normal with the values of 0.78 to 0.0655 for the mean and the standar deviation respectively.

<em>Normal (0.78,0.0655)</em>

Who's most brainiest to answer these 2 questions? Will mark ya'll brainiest. Pls show all work!

Answer:

A = picture attached

B = 51 in²

Step-by-step explanation:

The picture attached is the answer for part A. You use the dimensions you already know from the first picture to fill in the net of the slice of pie.

Area of the triangle = 1/2 (base × height)

A = 1/2 (4 × 6) = 1/2 (24) = 12

The area of the triangle is 12. The top is a triangle, but the bottom is also a triangle with the same area. Therefore, the area of the two triangles combined is 24 in². Next, we have to find the area of the rectangle at the sides of the pie.

Area of rectangle = length × width

A = 5 × 2.5 = 12.5

Since there are two rectangles with the same area on both sides of the pie, we can double it and get 25 in². We still have one rectangle left, the one at the back of the pie.

A = 6 × 2.5 = 15

Add the areas altogether to get the answer.

24 + 12.5 + 15 = 51.5 in²

I hope this helps. Sorry if Part B's answer is wrong.
