Question

Seven year old students at a elementary school were given 10 yard

Answer 1

Answer:

The correct option is a. 10 ≤ x ≤ 60, or x is from 10 to 60.

Step-by-step explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

Seven-year-old students at an elementary school were given a 10-yard head start in a race. The graph shows how far the average student ran in 30 seconds. A line graph with Distance, in yards, on the x axis and Age of Runner on the y axis. The x axis has a scale from 0 to 80 in increments of 10. The y axis has a scale of 0 to 8 in increments of 2. A straight line connecting 10, 7 and 60, 7 is drawn. Which statement best describes the domain of the function represented in the graph?

a. 10 ≤ x ≤ 60, or x is from 10 to 60

b. 7 ≤ x ≤ 60, or x is from 7 to 60

c. 7 ≤ x ≤ 10, or x is from 7 to 10

d. 0 ≤ x ≤ 10, or x is from 0 to 10

Note: See the attached photo for the graph referred to in the question.

The explanation of the answer is now given as follows:

In statistics, the domain of a function refers to the values in the x-axis where there is a corresponding value in the y-axis.

In this question, the only defined values for x are from 10 to 60 with a corresponding constant value of 7 in the y-axis.

Based on this, the correct statement that best describes the domain of the function represented in the graph is therefore option a. 10 ≤ x ≤ 60, or x is from 10 to 60.
