Answer:
The variance is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 21
The sum of squares is 
Generally the variance is mathematically represented as

substituting values


Answer:
12.06
Step-by-step explanation:
If emily's dog ate 6% of the cookies and theres 12 left
You need to add 6% and 12
That leaves you with a sum of 12.06
The sum of the inside angles of a 5 sided figure needs to equal 540 degrees.
Add all the angles together to equal 540 and solve for x. Once you have the value for x you can use that to figure out all the angles.
X-8 + 3x-11 + x + 8 + 2x + 7 + x = 540
Simplify by combing like terms:
8x - 4 = 540
Add 4 to both sides:
8x = 544
Divide both sides by 8:
X = 68
Now replace x with 68 in each angle and solve:
U = 68-8 = 60
V = 3(68)-11 = 204-11 = 193
W = 68 + 8 = 76
Y = 68
Z = 2(68) + 7 = 136 + 7 = 143
The surface area of the rectangular prism is 3668.94 m²
<h3>Calculating Surface area </h3>
From the question, we are to determine the surface area of the rectangular prism
Surface area of a rectangular prism is given by the formula,
Surface area = 2(lw + lh + wh)
Where l is the length
w is the width
and h is the height
From the given diagram,
l = 35.7 m
w = 25.5 m
h = 15.1 m
Putting the parameters into the formula, we get
Surface area = 2(35.7×25.5 + 35.7×15.1 + 25.5×15.1)
Surface area = 2(910.35 + 539.07 + 385.05)
Surface area = 2(1834.47)
Surface area = 3668.94 m²
Hence, the surface area of the rectangular prism is 3668.94 m²
