OLga [1]

Answer:

The graph is attached.

Step-by-step explanation:

The range of this data is the highest value, 22, subtracted by the lowest value, 1:  22-1 = 21.

Using boundaries, the first bar would go from 0.5-3.5; the second from 3.5-6.5; the third from 6.5-9.5; the fourth from 9.5-12.5; the fifth from 12.5-15.5; the sixth from 15.5-18.5; the seventh from 18.5-21.5; and the eighth from 21.5-24.5.

The frequency of the first bar, its height, would be 1; the height of the second bar is 2; the height of the third bar is 3; the height of the fourth bar is 2; the height of the fifth bar is 3; the height of the sixth bar is 1; the height of the seventh bar is 1; and the height of the eighth bar is 1.

HELP THIS IS DUE TODAY?!
shutvik [7]

52.5 Yards (yd).

7 + 7 = 14

14 + 14 = 28 ( 10 + 10 + 4 + 4)

14 + 28 = 42 (4 - 2 + 8 = 10 + 20 + 10)

42 + 10.5 = 52.5

⚠⚠ if you need to multiply this by itself (squaring is the proper name) then the answer is 2756.25 Yards.

Suppose f(x)=x^2. What is the graph of g(x)=1/2f(x)?
sp2606 [1]

9514 1404 393

Answer:

  see attached

Step-by-step explanation:

The graph of g(x) is a vertically scaled version of the graph of f(x). The scale factor is 1/2, so vertical height at a given value of x is 1/2 what it is for f(x). This will make the graph appear shorter and fatter than for f(x).

The graph of g(x) is attached.
