Just list the factors of 24. Those are the possible numbers of students that can be in each row.
1,2,3,4,6,8,12,24 are the possible row sizes.
Using the normal distribution, it is found that the replacement time that separates the top 18% from the bottom 82% is of 11.23 years.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean 
and standard deviation 
is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
In this problem, the mean and the standard deviation are, respectively, given by 
.
The desired value is the 82nd percentile, which is X when Z = 0.915, hence:
X - 9.4 = 0.915(2)
X = 11.23
The replacement time that separates the top 18% from the bottom 82% is of 11.23 years.

Answer:
Yes, it is a function
Step-by-step explanation:
anytime you want to test to see if the graph is a function, perform a vertical line test.
Basically if you drew a vertical line and the vertical line crosses the graph at only one point that means the graph is a function.
If it crosses on more than one point the graph is not a function.
Answer:
A and B
Step-by-step explanation:
Given
p -> Doubling the sides of a rectangle
q -> Area increases by factor of 4
From the question we understand that q depends on p.
This means that the original statement is option A which says p → q
The arrow from p to q indicates that if p is true then q is true.
Hence, option A is correct
Option B is also correct because it represents the inverse of (A) above.
I.e. if the sides of the triangle is not doubled, then the area won't increase by a factor of 4.
This in its actual sense represent negation or inverse statement.
Hence, options A and B answer the question while other options are incorrect.
