Answer:

9/22 or 40.9%

Explanation:

Probability describes the likelihood of an event. To find simple probability, like in this question, use division.

To find the probability of the first question being a free response, you first need to find the total number of questions. This can be done by adding together all of the given information. There are 10 multiple choice, 3 essays, and 9 free responses.

  • 10 + 3 + 9 = 22

This means that there are 22 total questions. Next, find how many of these questions are free-response. We know that there are 9 free responses and 22 questions in total. So, 9 out of 22 are free responses. This can be rewritten as 9/22.

If you want to find the percentage, simplify the fraction and convert it to a percentage.

  • 9/22 = 0.409

Then, move the decimal 2 places to the right. This gives you 40.9%, which is the probability of the first question being a free-response.

At what time do guests start arriving for the 9 a. M. ​ opening?
Umnica [9.8K]

The time guests should arrive for the 9 am opening is 8:30am.

<h3>What time should guests start arriving?</h3>

When guests are expected at an event, best practice is to arrive 15 minutes before the opening time. If 30 minutes is subtracted from 9am it is 8:30 am.

If guests aim to arrive at exactly at 9am, it is likely that they would not be at the opening on time.

Here are the options to this question: A. 1 a.m. B. 9 a.m. C. 6 a.m. D. ​8:30 a.m.
