Answer: C) 30.0 ounces

Step-by-step explanation:

Use one of the ordered pairs that are given to find the value of 'k', the CONSTANT of variation. This number will not change, hence the word 'constant'.

15 = k*6; dividing both sides by 6 we get k = 2.5; The equation used for the table is y = 2.5x

You can find any value now by using this formula.

y = 2.5*12

y = 30

On a map with a scale of 1 in. = 30 miles, the distance between Tarreytown and Hillville is 4 1/2 in. What is the actual distanc
Anit [1.1K]

The distance between the two towns is 75 miles.

<h3>What is the actual distance between the towns to the nearest mile?</h3>

We know that the scale of the map is 1 inch to 30 miles, this means that any measure that we get in inches in the map, should be multiplied by 30 to get the real measure in miles.

In this case, we know that in the map, the distance between the two towns is (4 + 1/2) inches.

Then the real distance in miles is given by:

d = (4 + 1/2)*30mi = 60mi + 15mi = 75mi

The distance between the two towns is 75 miles.

Seventh grade students were asked whether they participated in an after school activity. Complete the table below.
Natalka [10]

Answer:

Relative frequency of male nonparticipation is O.42

Step-by-step explanation:

Figure 1 is your partially filled frequency table.

1. Complete the table

(a) Total No

Total Yes + Total No = Total

     102     + Total No = 187

                   Total No = 187 - 102  

                                   = 85

 

(b) Female No

Male No  + Female  No = Total No

     40      + Female No =      85

                  Female No =       85 - 40

                                      =       45

(c) Female Yes

Female Yes + Female  No = Female Total

Female Yes +       45          =        95

Female Yes                         =        95 - 45

                                            =        50

(d) Male Yes

Male Yes + Female  Yes = Total Yes

Male Yes +         50          =     102

Male Yes                           =     102 - 50

                                          =     52

(e) Male Total

Male Yes + Male No = Male Total

     52      +       40     = Male Total

         Male Total        =       92

Figure 2 shows the completed table.

2. Frequency of Male No

There are 92 males, of whom 40 do not participate in an after-school activity.

The relative frequency of male nonparticipation is

40/92 = 0.43
