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
Answer:
Step-by-step explanation:
Lets say each ride is r
2.00r + 5.00 = 19.00
I believe it would be b.
explanation: use this rule: (x^a)^b = x^ab
4x-5=31
Add 5 to both sides
4x=36
Divide both sides by 4
x=9
Final answer: 9
It’s should be something like negative 7or 8
