I need help with this i will give brainest

The correct answer is d. ( aka the last one.)

Step-by-step explanation:

1) You know that 43 inches is your starting point

and 53 is your end. that tell you your equation will look so.ething like this - + 43 = 53

2) You know that she grew anaverage of 2.5 inches you just don't know how many years so you would write it as 2.5x. The x represents the unknown years. Giving you 2.5x + 43 = 53

3) Now you solve! Subtract 43 from both sides.

You should get 2.5x = 10.

4) Divide both side by 2.5 to get it away from x.

You should get 4! That means it was 4 years ago that Jessica was in 3rd grade.

median because there is an outlier

Step-by-step explanation: Taking the mean or average of something with outliers will skew the data. In this case, the two lower outliers will make the center lower if you take the mean. That makes the median better.
