Answer:
The answer is 3.
Step-by-step explanation:
C=dxpi
18x3.14=56.52
6x3.14=18.84
56.52/18.84=3
Answer:
The answers are options A and B
First solve the inequality
7x < 21
Divide both sides by 7
That's
7x/7 < 21/7
x < 3
The values that satisfy the inequality are
1 and 2 since they are both less than 3
Hope this helps you.
Answer:
Step-by-step explanation:
We are given with two equations
first equation is 
second equation is
we find the result of subtracting two equation
subtract the second equation from the first, so
first equation - second equation, multiply second equation by -1 and then add it with first equation
Now add both equations, we get
E) 12 minutes
A normal curve has approximately 95% of graph between mean - 2sd and mean + 2sd
So 95% of the times will be between 0 and 12 minutes. 6 - 2x3 to 6 + 2x3
2.5% will take over 12 minutes
Strangely 2.5% will also take less than 0 minutes to process which shows the normal curve is not perfect in this example.
