The answer is 29.03%. because there are 2 people who are 15-19 and there are 7 people between 20-24. 7+2=9. and there are a total of 31 people. so 9 out 31 as a percent is 29.03%. hope this helps. please give me a brainliest

Answer: Choice D</h3>
To calculate a point estimate, we need to know the sample size.
===========================================================
Explanation:
Let's go through the answer choices.
- A) False. A sample statistic could equal to the population parameter. It won't always happen, but it might happen sometimes (in rare cases).
- B) False. Point estimates are only defined for populations. They estimate a population parameter. For example, the sample mean xbar is a point estimate of the population mean (mu).
- C) False. In practice, we will hardly know anything about the population. This includes the population size. The goal of statistics is to measure population parameters by using sample statistics as estimation methods.
- D) True. We can easily calculate the sample size because it is relatively much smaller compared to the population. Plus, when selecting the sample, the sample size is often pre-determined to some set number. The sample size will help us determine things like the sample mean and the sample proportion.
Answer: Same-Side Interior Angles Theorem
Step-by-step explanation:
- Same-Side Interior Angles Theorem says that when two lines are parallel and a transversal intersects it , then the angles on the same interior side are supplementary.
We are given that Two parallel lines PQ and RS are drawn with KL as a transversal intersecting PQ at point M and RS at point N.
Angle QMN is shown congruent to angle LNS.
Also, angle QML and angle SNK are the angles lies on the same side of the transversal.
It means the measure of angle QML is supplementary to the measure of angle SNK [ By Same-Side Interior Angles Theorem ]
