Answer:
The net change is - $0.30
Step-by-step explanation:
3.5 - 3.7 = -.2
-.2 + 3.3 = 3.1
3.1 - 3.4 = -.3
Answer:
3,200
Step-by-step explanation:
Your answer should be in one variable equation by using the Y and W angle. They are equal if you match with the same angle size.
7x=6x+11
(7-6)x = 11
x = 11
We got the x value, so suvtitute into W angle :
7x
=7(11)
= 77
Hope this helps :)
The answer is 84. Your Welcome!
The standard deviation of a sample is proportional to 1/√N where N is the sample size. In this case we are decreasing N by half, so we can write:
1/√(N/2) = √2 / √N
If we say that our standard deviation is proportional to 1/√N, the difference that occurred from decreasing the sample size by half resulted in an increase in the standard deviation by a factor of √2.
Therefore, the standard deviation is multiplied by √2.
