in this case y is 1 when x is 2
Step-by-step explanation:
Aww(: well Mitt Romney is a republican candidate
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.
Answer:
She has 16 brownies
Step-by-step explanation:
Initially cut rectangular pan in to two halves.
Then cut each half in half again.
Now total pieces = 4
Now repeat cutting half on other side:
total pieces =8
Now divide each half into another half.
total pieces = 8 x 2 = 16
As can be shown in figure:
Black = first half
pink = dividing each half into another half.
