Answer: average = 4
standard deviation = 0.38
<u>Step-by-step explanation:</u>
Average (aka Mean) = (4 + 3.5 + 4.5 + 4.2 + 3.8)/5 = 20/5 = 4
Answer:
<em>The correct option is: B. 9</em>
Step-by-step explanation:
The number of tennis balls, , in layers of the square pyramid is given by:
As the stack of the tennis balls is in shape of a square pyramid, that means <u>in the top layer, there will be one ball</u>. So,
Now, if then
If then
If then
That means, the number of tennis balls from the top layer will be: 1, 5, 14, 30, .......
So, the number of tennis balls that Coach Kunal could not have is 9.
The maximum pounds of celery she can buy is 3.25 pounds.
<h3>What are the linear equations that represent the question?</h3>
1.5c = o equation 1
1.50o + 1.80c = 8.10 equation 2
Where:
o = pounds of onions
c = pounds of celery
How many pounds of celery can she buy?
Substitute for o in equation 2 using equation 1
1.50(1.50) + 1.80c = 8.10
2.25 + 1.80c = 8.10
1.80 = 8.10 - 2.25
1.80c = 5.85
c = 5.85 / 1.80
c = 3.25 pounds

Express your length and width as algebraic expressions:
width = x
length = 4x
Use the formula for the perimeter of a rectangle to solve for x:
perimeter = 2(length) + 2(width)
50 = 2(4x) + 2(x)
50 = 8x + 2x
50 = 10x
5 = x
The width (x) is 5 feet and the length (4x) is 20 feet.
