It would be 10 the slope is always with the x
What is 7x5x4, it is 140 so the volume is 140in^3 its a pretty simple problem
The answer is 3. 4 because 4 doesn’t have a variable :)
Answer:
1727 students
Step-by-step explanation:
Here we have the formula for sample size given as

Where:
p = Mean
ME = Margin of error = 3
z = z score
Therefore, we have
p = 150/240 = 0.625
z at 99 % = 2.575
ME =
3%
Therefore 
The number of students Professor York have to sample to estimate the proportion of all Oxnard University students who watch more than 10 hours of television each week within ±3 percent with 99 percent confidence = 1727 students.
