Answer:

(4\pi -2)49

Step-by-step explanation:

let radius of the circle be r = 14 feet.

then side of the square would be \sqrt{2}r

therefore area of the square = 2r^{2}

area of remaining circle = area of circle - area of square

                                        4\pi r^2-2r^{2}

                                        =(4\pi -2)49

I need help please ^^

Answer:

  see below

Step-by-step explanation:

Usually, we're concerned about the relationship of y to x. Here, the question is asking you to consider the relationship of x to y.

The easiest way to find the answer to this one is to check the given explanations to see which is true. You can pretty much ignore the first row of the table and just look at the second row where x=5 and y=15.

  • it is NOT TRUE that x is 3 times y (5 is not 3 times 15)
  • it is TRUE that x is 1/3 of y (5 is 1/3 of 15)
  • it is NOT TRUE that x is 5 times y (5 is not 5 times 15)
  • it is NOT TRUE that x is 1/5 of y (5 is not 1/5 of 15)

_____

If you know your multiplication tables, you know that 15 = 3×5, so ...

  5 = 15/3

  5 = (1/3) × 15

The relationship of these numbers should not be a mystery.

What percentage of the data falls outside 1 standard deviation of the mean?
Alik [6]

We all know about the bell curve i.e. normal distribution curve. It is centered about the mean and spread equally on each side.

We describe the area of the curve with the help of standard deviations.

With in 1 standard deviation about the mean i.e. from -1 s.d. (left of mean) to +1 s.d. (right of mean), it covers 68% of the total area of curve.

So, the data that falls outside 1 standard deviation of the mean would be equal to (100% - 68%) i.e. 32%.

So, 32% is the final answer.

Find the mean of the following set of data. Round your answer to two decimal places.
Vera_Pavlovna [14]

Answer:

41.23

Step-by-step explanation:

Mean = (23 + 50 + 49 + 48 + 49 + 32 + 37 + 40 + 41 + 42 + 41 + 41 + 43) ÷ 13

Mean = 536 ÷ 13 = 41.23 (rounded up to two decimal places)
