Answer:
Now we are supposed to find probabilities that the response time is between 5 and 10 minutes i.e P(5<x<10)
Formula : 
at x = 5
at x = 10
P(-2<z<0.6315)=P(z<0.6315)-P(z<-2)
Refer the z table
P(-2<z<10)=0.7357-0.0228=0.7129
So, the probability that response time is between 5 and 10 minutes is 0.7129
b)the response time is less than 5 minutes
at x = 5
P(x<5)=P(z<-2)=0.0228
So, the probability that the response time is less than 5 minutes is 0.0228
c)the response time is more than 10 minutes
at x = 10
P(x>10) = 1-P(x<10) = 1-P(z<0.63) = 1-0.7357 = 0.2643
So, The probability that the response time is more than 10 minutes is 0.2643
The number of pieces per stack after 3 cuts represented by a power expression can be written as 
- The number of equal pieces per cut = 3
- The number of cuts made = 3
<u>Using a power </u><u>expression</u><u> </u><u>:</u>
- The number of of equal pieces per cut is raised to a power which represents the number of cuts made
- Thus we have
- After 1 cut ;
- After 2 cuts ;
- After 3 cuts ;
Therefore, the Number of pieces present in stack after 3 cuts is

Answer:
Step-by-step explanation:
Total Students = 28
Brown Hair = 22
NOT Brown Hair = 28 - 22 = 6
The probability of an event is the number of that event divided by total number.
So, let denote probability of without brown hair be P(NOT BROWN). So, we can say:
P(NOT BROWN) = 6/28
Reducing, we get:
P(NOT BROWN) = 3/14
Subtract x on both sides the result you divide it by 5
I think its c hope this helps sorry if it dont
