Answer:
I believe it is 55°.
I can't remember the exact steps for this tho.
I hope it is right! good luck!
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
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:


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


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