tan( 31 ) = x / 39
0.600860619 = x / 39
x = 0.600860619 × 39
x = 23.433564141

Short answer: NO.
28 cups is exactly equal to 14 pints. (There are 2 cups per pint.)

b. Invalid, because the sample may not be representative of the population.
Step-by-step explanation:
A sample of around 10% of the population is needed to be representative.
In this question:
We have a population of 500,000, and a sample of 10,000.
10,000/500,000 = 1/50 = 0.02 = 2% of the population, so not representative, and option b is correct.
