The 50th percentile is the median so the z score will be 0
3.643 x 10^-1 would be the answer
It has to be 438 because any number that is 5 or higher must be rounded up so 438 could be rounded up to 440
Answer:
12
Step-by-step explanation:
AC = BD (as the diagonal of the rectangle)
4x-60=30-x
4x+x = 30+60
5x = 90
x = 90/5
x = 18
=> BD = 30-18 = 12
The hypothenuse is the opposite side of the right angle
so that means that in this triangle the hypotenuse is 7
