The number of students in the class is given by the sum of the frequency
of each score.
- <u>There are at least 9 students in the class</u>.
Reasons:
When the class scores are arranged in increasing order, we have;
Sean's position = 5 th = The fifth lowest score
Therefore;
- The number of scores lower than Sean's score = 4
When the scores are arranged in decreasing order, we have;
Sean's position = 5 th = Fifth highest score
Therefore;
- The number of scores higher than Sean's score = 4
- The total number of different scores in the class = 4 + 1 + 4 = 9
Given that two or more students can have the same score, the frequency
of each score, determines the number of students in the class, we have;
- <u>The number of students in the class, n ≥ 9</u>

Answer:
5.04 centimeters= 16.128 meters
Step-by-step explanation:
If we now that 4y equals to x, that means we can replace x with 4y.
Therefore we can write: 4y+2y = 12
We can summarize that to 6y = 12.
If we divide both sides with 6, you get y = 2
In order to solve for x, we can use the second equation and just replace y with value we just got (y=2).
We can write: x+2*2=12
Now you move 2*2 (which is 4) to the other side: x=12-4
Now you get: x = 8
Y-intercept: (0,-3)
x-intercept: (0,5)
