Answer:

It is 91.01 m/s faster than the Singaporean sprinter

Convert km/hr to m/s

U get 101.38m/s (speed of bullet train)

Speed of the Singaporean sprinter is 10.37m/s

So subtracting the train speed from the sprinter's speed,

101.38 - 10.35= 91.01m/s

Adam has a playhouse in his backyard that is shaped like a square prism with a squarepyramid for the roof. What is the volume of
Ainat [17]

Answer:

51 cubic feet

Step-by-step explanation:

This is basically a rectangular prism + pyramid.

Volume of rectangular prism = length * width * height

Volume of square pyramid = 1/3 * area of base * height

The rectangular prism's dimensions are 3 x 3 x 5 ,  so volume = 3*3*5 = 45

The pyramid's base is a square with side 3, so area of base = 3 * 3 = 9

The height is 2, we find the volume using the formula stated above as:

1/3 * 9 * 2 = 6

Volume of Playhouse = volume of rectangular prism + volume of pyramid

Volume of Playhouse = 45 + 6 = 51 cubic feet

Harman [31]

Using addition of variables, it is found that the mean of S is of 73 and the standard deviation is of 8.5.

<h3>What happens to the mean and the standard deviation when two variables are added?</h3>
  • The mean is the sum of the means.
  • The standard deviation is the square root of the sum of variances.

In this problem, for variables A and B, we have that:

\mu_A = 35.5, \sigma_A = 5.1

\mu_B = 37.3, \sigma_B = 6.8

Variable S is the sum of A and B, hence:

\mu_S = \mu_A + \mu_B = 35.5 + 37.3 = 73

\sigma_S = \sqrt{\sigma_A^2 + \sigma_B^2} = \sqrt{5.1^2 + 6.8^2} = 8.5

The mean of S is of 73 and the standard deviation is of 8.5.
