100%/x%=300/111(100/x)*x=(300/111)*x 100=2.7027027027*x 100/2.7027027027=x 37=x x=37%
If u were to add 5x+20=9x you’d get x=5

Answer:
The z-distribution should be used for this problem.
Step-by-step explanation:
The population distribution is assumed to be normal. Which distribution to use?
If we have the standard deviation for the sample, we use the t-distribution.
If we use the standard deviation for the population, we use the z-distribution.
There is a known standard deviation of 2.2 minutes.
This means that 2.2 is the population standard deviation, and thus, the z-distribution should be used for this problem.
Answer:
x=10,−10
simple, it could be negative OR positive :D
