Answer:

The correct answer would be C

Step-by-step explanation:

Looking at the data, you can tell that the first two are going to be wrong. The minimum is 1, and the maximum is 5.

A mode, by definition, is the number that appears most in the data. According to answer D, 3 appears 3 times in the data. That is incorrect, as 3 only appears twice in the data.

This leaves only answer C. We need to make sure it's correct. The answer mentions the mean as a value between 2 and 3. Mean is the average. To find the average, you must add all the values together first.

1 + 2 + 5 + 3 + 2 + 2 + 5 + 3 = 23

Then, you must divide the value by the number of data given. There are 8 numbers here, so you must divide 23 by 8.

23/8 = 2.875

2.875 is between the numbers 2 and 3 like answer C said, so C is correct.

PLEASEHELP!!!!!!

Using proportions, it is found that the speed of the runners are of 16 mph and of 20 mph.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount.

After 30 minutes, the runners are 2 miles apart, hence the second runner is 4 miles per hour faster than the second, that is:

$v_2 = v_1 + 4$ .

The first runner's speed is 4/5 of the speed of the second runner, hence:

$v_1 = \frac{4}{5}v_2$

$v_1 = \frac{4}{5}(v_1 + 4)$

$\frac{1}{5}v_1 = \frac{16}{5}$

$v_1 = 16$

$v_2 = 16 + 4 = 20$

Hence, the speed of the runners are of 16 mph and of 20 mph.

Could you add 7/12 2/3

muminat

Yes, you need to make the denominators the same. 2/3 becomes 8/12. So now you add 7/12 and 8/12, getting 15/12. But you're not done you need to simplify 15/12. The answer is 1 1/4.
