Answer: 0.0775
Step-by-step explanation:
Given : Mean :
Standard deviation :
Sample size :
Since its normal distribution , then the formula to calculate the z-score is given by :-
For x= 28.2 hours
For x= 30 hours
The P- value =
Hence, the probabiliy that the average time spent stydying for the sampe was between 28.2 and 30 hours = 0.0775
Answer:
Step-by-step explanation:
You transcribed the equation incorrectly, but that's okay as I do know the correct volume formula. That is:
v = πr²h
In other words, the volume of a cylinder is simply the area of one of its circular ends, multiplied by its length. Now that we have that, let's solve for h:
So the height of the cylinder can be calculated given the volume and the radius, simply by dividing the volume by pi times the square of its radius.
