Answer:
3 3/8
Step-by-step explanation:
4 5 27
--- - ----- = ------- or 3 3/8
1 8 8
Answer:
81.8%
Step-by-step explanation:
Mean = 
Standard deviation = 
Now we are supposed to find out what percent of the numbers fall between 35 and 50

Substitute the values

Now for P(35<x<50)
Substitute x = 35


Substitute x = 50


So, P(-1<z<2)
P(z<2)-P(z<-1)
=0.9772-0.1587
=0.8185
= 
=81.8%
Hence 81.8% percent of the numbers fall between 35 and 50
(X-8)(x+2) is the factored equation. Ur zeros r -2 and 8. So the largest should be 8?
