Fiona has to plot a histogram of the given data. 82, 83, 89, 67, 65, 88, 66, 69, 83, 81, 94, 68, 82, 69, 86, 83, 88, 62, 64, 93 which frequency table should she use for the histogram? a. interval 60–70 70–80 80–90 90–100 frequency 8 0 10 2 b. interval 56–63 63–70 70–77 77–84 84–91 91–98 frequency 1 7 0 5 5 2 c. interval 50–70 70–80 80–85 85–90 90–100 frequency 8 0 6 4 2 d. interval 60–75 75–90 90–105 frequency 8 10 2

B. Interval56–63 63–7070–7777–8484–9191–98 Frequency 170552

Because you want to really see the different kind of scores the person gets from the data.

The answer is C.

Step-by-step explanation:

There are 8 in between 50-70, 0 in between 70-80, 6 in between 80-85, 4 in between 85-90 and 2 in between 90-100.  B is incorrect because there are 6 numbers in between 77-84.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
