The following data points represent how many houses Gregg the garbage man visited each day last week. 12, 28, 33, 37, 23, 14, 9

The histogram for the data is attached below.

Step-by-step explanation:

The data for the number of houses Gregg the garbage man visited each day last week is as follows:

S = {12, 28, 33, 37, 23, 14, 9}

In this case we need to create a histogram for the provided data.

According to the graph provided we know that the class intervals are:

CI = 0 - 10, 10 - 20, 20 - 30, 30 - 40

The frequency distribution table is as follows:

Class Interval     Frequency

    0 - 10                    1

   10 - 20                  2

  20 - 30                  2

  30 - 40                  2

The histogram for the data is attached below.

There are 1 squares in 0-10

There are 2 squares in 10-20

There are 2 squares in 20-30

There are 2 squares in 30-40

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
