Answer: Simple random sample

Step-by-step explanation:

  • A simple random sample is an unbiased representation of a sample of a population.  A subset of a statistical population is known as a simple random sample in which each member of the subset has an equal probability of being selected.

Given: In a small town there are 300 renters and 1000 homeowners. 100 renters and 100 homeowners are randomly selected to participate in a study involving annual household income.

Here each renters and homeowners has the same probability of getting selected.

Therefore a simple random sampling is used in this study.

Calvin had 30 minutes in time-out. For the first 23 1/3 minutes, Calvin counted spots on the ceiling. For the rest of the time,
scoundrel [369]

Answer: \frac{20}{3}\ minutes or 6 \frac{2}{3}\ minutes

Step-by-step explanation:

For this exercise you can convert the mixed number to an improper fraction:

1. Multiply the whole number part by the denominator of the fraction.

2. Add the product obtained and the numerator of the fraction (This will be the new numerator).

3. The denominator does not change.

Then:

23\frac{1}{3}= \frac{(23*3)+1}{3}= \frac{70}{3}\ minutes

You know that he had 30 minutes in time-out, he counted spots on the ceiling for \frac{70}{3} minutes and the rest of the time he made faces at his stuffed tiger.

Then, in order to calculate the time Calvin spent making faces at his stuffed tiger, you need to subract 30 minutes and \frac{70}{3} minutes:

30\ min-\frac{70}{3}=(\frac{3(30)-70}{3})=\frac{20}{3}\ minutes or 6 \frac{2}{3}\ minutes
