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:
The weight of Rachel is less than 40 Pounds.
The weight of Stephanie is less than 120 Pounds
Step-by-step explanation:
Sum of both both their weights is less than 160 pounds.
Let the weight of Rachel = k Pounds
⇒The weight of Stephanie = (3k) pounds
Now, according to the question:
k + 3k < 160
or, 4k < 160
⇒ k < 160/ 4 = 40
or, k < 40
⇒ The weight of Rachel is less than 40 Pounds.
and The weight of Stephanie is less than (3 k = 3 x 40) 120 Pounds
