Answer: the answer is B
Step-by-step explanation:
it’s on edge
Using the empirical rule 68% would fall within one standard deviation of the mean.
The standard deviation is given as 2 inches and the mean is 49 inches.
Since it is only one standard deviation find the lower number by subtracting the standard deviation from the mean and find the higher number by adding the standard deviation to the mean.
49 - 2 = 47
49 + 2 = 51
68% would be between 47 inches and 51 inches tall.
4y - y + 7y
4y - y = 3y
3y + 7y = 10y
10y is your answer
hope this helps
