Answer:

Charles completed the quiz problems at the slowest rate

Step-by-step explanation:

we know that

To find out the unit rate divide the number of quiz problems by the time employed

1) Maya completed 15 quiz problems in 10 minutes

so

\frac{15}{10}=1.5\ quiz\ problems\ per\ minute

2) Andrew completed 12 quiz problems in 8 minutes

so

\frac{12}{8}=1.5\ quiz\ problems\ per\ minute

3) Charles completed 16 quiz problems in 16 minutes

so

\frac{16}{16}=1\ quiz\ problem\ per\ minute

Compare the unit rates

1 < 1.5

therefore

Charles completed the quiz problems at the slowest rate

PLS HELP!!!!!! 55 points!!!!!! Create an experiment about the probabilities associated with choosing a candidate for class presi
NemiM [27]

(How to find) Theoretical probability is what we expect to happen, where experimental probability is what actually happens when we try it out. The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes.

(How to solve) Theoretical probability is a method to express the likelihood that something will occur. It is calculated by dividing the number of favorable outcomes by the total possible outcomes. The result is a ratio that can be expressed as a fraction (like 2/5), or a decimal

(How to experiment) Experimental probability is the results of an experiment, let's say for the sake of an example marbles in a bag. Experimental probability would be drawing marbles out of the bag and recording the results. Theoretical probability is calculating the probability of it happening, not actually going out and experimenting.

(Example) The theoretical probability of an event occurring is an "expected" probability based upon knowledge of the situation. It is the number of favorable outcomes to the number of possible outcomes. Example: Find the probability of rolling a 6 on a fair die.
