Answer:
Part A: 20 students
Part B: 4 hours
Step-by-step explanation:
Part A:
To find the number of students surveyed, we count the number of x there are in the graph.
students = 1 + 2 + 3 + 5 + 1 + 1 + 3 + 2 + 2 = 20
Part B:
To find the mean, we need to find the total number of hours volunteered first.
hours = 1x0 + 2x1 + 3x3 + 5x3 + 1x4 + 1x5 + 3x6 + 2x7 + 2x8 = 80
Now, we can find the mean. We divide the total number of hours volunteered by the number of students.
Mean = 80 ÷ 20 = 4
Answer:
so you plug in the numbers you were given (-2, -1, 0, 1, 2) into the x value one at a time and you will get the other point for that pair so (3/5)^-2 and whatever number you get is the 2nd number to that ordered pair

Answer:
Step-by-step explanation:
You can easily find the slope by using two points. Let’s use (13, 11) and (14, 6)
We look at the slope equation as: y2 - y1 divided by x2 and x1.
13 = x1 11= y1 and 14= x2 6=y2
Plug in: 6-11/14-13 and solve
Answer: -5
Hope I made sense :)
