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 s
tudent 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? 10 ≤ x ≤ 60, or x is from 10 to 60 7 ≤ x ≤ 60, or x is from 7 to 60 7 ≤ x ≤ 10, or x is from 7 to 10 0 ≤ x ≤ 10, or x is from 0 to 10

Answer:
A: 10 ≤ x ≤ 60, or x is from 10 to 60
Step-by-step explanation:
The <em>domain of the function</em> is, by definition, the values in the x-axis where the function exists, or in other words, has a corresponding value in the y-axis.
The only defined values for x in this problem are from 10 to 60, which have a value of 7 constant in the y-axis.
Please find attached a graph for the function described.

Answer:
The mean is 5.309.
Step-by-step explanation:
Given group of data,
4.1, 8.9, 3.2, 1.9, 7.3, 6.3, 6.7, 8.6, 3.2, 2.3, 5.9,
Sum = 4.1+ 8.9 + 3.2 + 1.9 + 7.3 + 6.3 + 6.7 + 8.6 + 3.2 + 2.3 + 5.9 = 58.4,
Also, number of observations in the data = 11,
We know that,
Hence, the mean of given data =
