Answer:
Option B. 7.5 is the correct answer
Step-by-step explanation:
Let us define standard deviation first.
Standard deviation is the square root of variance. Standard Deviation tells us that how far are the values in a data set from the mean.
Now, if a constant is subtracted from all values of a dataset, the standard deviation remains the same. Only the origin or mean of the data changes by subtracting a constant from whole data set.
Given that the standard deviation of dataset is 7.5
Subtracting 2 from each value of dataset will not change the standard deviation as 2 is a constant.
Hence,
Option B. 7.5 is the correct answer

Answer: There are 27 trees that Abe can plant in each row. And there are 1 pine tree and 2 oak tree in each row.
Explanation:
Since we have given that
Number of oak trees = 54
Number of pine trees = 27
According to question, we have given that Abe wants to plant the trees in rows that all have the same number of trees and are made up of only one type of tree.
So, the greatest number of trees is given by
Hence, there are 27 trees that Abe can plant in each row.
Therefore, there are
Hi Grace!
4p + 12 - 3q - 4p - 18 + 6q
Combine like terms
4p - 4p + 12 - 18 - 3q + 6q
= -6 + 3q
The correct answer is option D
