You can obtain information about the mean population by taking a random sample of it and taking the average of that sample. The Law of big Numbers says that the bigger the sample, the more likely we will be closer to the real mean value. In other words, the margin of error is less likely to be big.

Answer:
Step-by-step explanation:
ABC right angled at B such that
BAC=2×ACB.
Let ACB = x
BAC = 2x
ABC = 90°
And the sum of angle in a triangle is 180°
:- x + 2x + 90° = 180°
Collecting like terms
3x = 180° - 90°
3x = 90°
x = 90/3
x = 30°
Angle ACB = x = 30°
Angle BAC = 2x = 2×30° = 60°
You said that "each truck carries the same weight".
This means that the shipping manager DIVIDED the paper equally
among the four trucks. Does that give you any ideas, hmm ?
How about DIVIDING the 110.4 tons into 4 equal parts, then
put one part on each truck.
110.4 tons DIVIDED by 4 = 27.6 tons .
