hypotenuse =sqrt( a^ + b^
10^2 = 100
14^2 = 196
196+100 = 296
sqrt(296) = 17.20
Answer is D. 17.20
A) Commission made last week is $ 288
B) Commissions earned in a year,treating a year as having exactly 52 weeks is $ 14976

To find the commissions earned in a year, treating a year as having exactly 52 weeks
Therefore,

Thus commissions earned in a year,treating a year as having exactly 52 weeks is $ 14976
AB=DE is a true statement
Multiply by 4 on both sides. This results into:
24 = a + 8
If 8 is substracted in both sides then a would be:
16 = a
The mean is 89 the median is 86 the mode is 85 Hope this helps!
(technically the mean is like 88.7 so I just rounded up to get 89)
