Question

I really need help with answering A and B

Answer 1

A.) 200cm
B.) 206cm

A explanation.) To find the mean, you add all the heights and divide by 5 (how many numbers there are), this gives you 1000 divided by 5, which equals exactly 200cm.

B explanation.) I tried the equation with numbers higher than 202, going up one each time, and 206 was the one that equaled exactly 201.
