The mean is not the same thing as median
mean=78+81+85+87=331
mean=331/4=82.75
median is the middle number, but you have a par set of numbers, so your median will be the middle numbers 78,81,85,87 , which are 81+85=166, 166/2=83
83 is your median
A = lw
44 = 3 2/3 w
w = 44 / (3 2/3)
w = 12
The ratio is 14:5, as 42 divided by 3 is 14 and 15 divided by 3 is 5.
No because equivalent is like 5/10 so it's not right
