Mila [183]

Answer:

  • d. Mateo scored as well as or better than 55% of his classmates, with a score of 82.

Step-by-step explanation:

  • Mateo scored in the 55th percentile of his class on the latest math exam. What does this mean in relation to the data set and what did he score on the exam?

{35, 42, 55, 68, 69, 72, 72, 77, 78, 78, 82, 85, 87, 88, 90, 93, 94, 96, 96, 99)  

  • a. Mateo scored a 55% on his exam.
  • b. Mateo scored as well as or better than 55% of his classmates, with a score of 78.
  • c. Mateo scored worse than 55% of his classmates, with a score of 78.
  • d. Mateo scored as well as or better than 55% of his classmates, with a score of 82.
  • e. Mateo scored worse than 55% of his classmates, with a score of 82.
<h3>Solution</h3>

There are scores of 20 students. Each score is equivalent of 100%/20 = 5%

The easy way to understand Mateo' s place is to compare scores against 5% slots.

<em>See attached.</em>

We can also get the average score

<u>Sum </u>

  • ∑ {35, 42, 55, 68, 69, 72, 72, 77, 78, 78, 82, 85, 87, 88, 90, 93, 94, 96, 96, 99) = 1556

<u>Average or mean score:</u>

  • 1556/20 = 77.8

This is matching the 50% score.

As we see Mateo scored 82 which is matching 55%.

Correct option is d.

Which statement BEST describes the relationship between whole numbers and natural numbers shown in the diagram?
NeX [460]

Answer:

The correct option is B.

Step-by-step explanation:

Consider the diagram below.

It is a Venn diagram.

The diagram shows that all the natural numbers are contained in the set of all the whole numbers.

This implies that all natural numbers are whole numbers.

Then the statement best describing the relationship between whole numbers and natural numbers is:

(B) The diagram shows that natural numbers are a subset of whole numbers,  because all natural numbers are whole numbers.

Thus, the correct option is B.
