The samples he chose may not be a representative sample because the number of students per foreign language class may not be the same. One class may have a very large number of students while another may have only a few. Taking equal number of students per class is not a representative sample.<span />
Answer:
m = 0.2 kg.
Step-by-step explanation:
Joint variation:
Q = kmT where k is a constant.
Subsituting the given values:
20930 = k*1*5
k = 20930 / 5 = 4186.
So the relation is:
Q = 4186mT
When Q = 8372 and T = 10:
8372 = 4186 * m * 10
m = 8372 / (4186*10)
m = 0.2 kg.
This is the mixed number you're looking for: 2 1/2
(2 and a half)
