The value of g = 144 solved by using direct proportion.
<h3>What is a direct proportion?</h3>Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value. It is represented by the proportional symbol, ∝.
Given that,
h = , j =
, g = 4
g ∝ hj
g = khj
where k is a constant.
4 = k××
k = 24
Also given that,
g = ? , h =2, j = 3
g = khj
g = 24×2×3
g = 144
Hence, The value of g = 144.

Answer:
- d. Mateo scored as well as or better than 55% of his classmates, with a score of 82.
Step-by-step explanation:
- Mateo scored in the 55th percentile of his class on the latest math exam. What does this mean in relation to the data set and what did he score on the exam?
{35, 42, 55, 68, 69, 72, 72, 77, 78, 78, 82, 85, 87, 88, 90, 93, 94, 96, 96, 99)
- a. Mateo scored a 55% on his exam.
- b. Mateo scored as well as or better than 55% of his classmates, with a score of 78.
- c. Mateo scored worse than 55% of his classmates, with a score of 78.
- d. Mateo scored as well as or better than 55% of his classmates, with a score of 82.
- e. Mateo scored worse than 55% of his classmates, with a score of 82.
There are scores of 20 students. Each score is equivalent of 100%/20 = 5%
The easy way to understand Mateo' s place is to compare scores against 5% slots.
<em>See attached.</em>
We can also get the average score
<u>Sum </u>
- ∑ {35, 42, 55, 68, 69, 72, 72, 77, 78, 78, 82, 85, 87, 88, 90, 93, 94, 96, 96, 99) = 1556
<u>Average or mean score:</u>
- 1556/20 = 77.8
This is matching the 50% score.
As we see Mateo scored 82 which is matching 55%.
Correct option is d.
