To compare the two classes, the Coefficient of Variation (COV) can be used. The formula for COV is this:
C = s / x
where s is the standard deviation and x is the mean
For the first class:
C1 = 10.2 / 75.5
C1 = 0.1351 (13.51%)
For the second class:
C2 = 22.5 / 75.5
C2 = 0.2980 (29.80%)
The COV is a test of homogeneity. Looking at the values, the first class has more students having a grade closer to the average than the second class.
The number of teaspoons of sugar that Mr. P. consumes is = 56.7 teaspoons.
<h3>Calculation of total sugar quantity</h3>
The total amount of cola taken is 8-ounce
To covert ounce to grams , the following is carried out;
1 ounce =28.35g
8 ounce = X
Xg = 8 × 28.35
X = 226.8g
But one teaspoon = 4 grams
X teaspoon = 226.8g
cross multiply to solve for x
X = 226.8g/ 4
X = 56.7 teaspoons
Therefore, the number of teaspoons of sugar that Mr. P. consumes is = 56.7 teaspoons.

Not all functions have inverse functions. Those that do are called invertible. For a function f: X → Y to have an inverse, it must have the property that for every y in Y, there is exactly one x in X such that f(x) = y.
