Using proportions, it is found that:
- Andrew gets R 1850.
- Each of Brendan and Clair get R 1387.5.
A proportion is a fraction of total amount.
In this problem, the total amount divided is R 4625.
For every R4 Andrew gets, both Brendan and Clair gets R3, hence the ratio is 4:3:3, which means that:
- Andrew gets
of the total amount.
- Brendan gets
of the total amount.
- Clair gets

Answer:
Due to the higher Z-score, Kamala had the best GPA when compared to other students at her school.
Step-by-step explanation:
Z-score:
In a set with mean and standard deviation
, the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
In this question:
Whichever student's GPA had the higher z-score had the best GPA compared to other students.
Thuy 2.5 3.2 0.8
This means that
The z-score is:
Vichet 88 75 20
This means that
The z-score is:
Kamala 8.9 8 0.4
This means that
The z-score is:
Due to the higher Z-score, Kamala had the best GPA when compared to other students at her school.
