Answer:
--- Mean
-- Variance
--- Standard deviation
Step-by-step explanation:
Given
<u>Solving (a): The population mean</u>
This is calculated as:
So, we have:
<u>Solving (b): The population variance</u>
First, calculate:
using:
So, we have:
So, the population variance is:
Solving (c): The population standard deviation
This is calculated as:
Answer: 2/9 is larger
the reason for this is it is more precise the longer and farther you go and bye the time you hit 45 you have 2/9=10/45 and 1/5=9/45 not big but the gap gets bigger the further you go.
Answer:
23 peaches (don't forget to label!!!! only if needed)
Hope it helps!!!!!!!!!!!!
Step-by-step explanation:
67-44=23
We can assign variables to each side:
x = first side
y = second side
z = third side
We will assume the "one side" that is greater than the second side is the first side. Since it is "2 times the second side" we can write this as:
x = 2y
Since the third side is 5ft longer than the second side, we can write this as:
y + 5 = z
Perimeter of the triangle (49ft):
x + y + z = 49
We can substitute everything we know.
(2y) + y + (y + 5) = 49
4y + 5 = 49
4y = 44
y = 11
Now we can solve for the other sides with what we have for y.
x = 2(11)
x = 22
11 + 5 = z
16 = z
Add to check.
22 + 11 + 16
33 + 16
49
Therefore, the side lengths are [ 22, 11, and 16 ]
Best of Luck!
I believe 11 centimeters is the answer.
