Select the correct answer.

a fitness club surveyed men and women about their preferred weight-loss methods. this table gives the results from the survey.
diet only exercise only diet and exercise
men 7 28 15
women 22 18 10

which table should you use to determine the percentage of women among the people who prefer exercise only? round your answers to the nearest hundredth.
a.
diet only exercise only diet and exercise
men 0.26 0.64 0.58
women 0.74 0.36 0.42
b.
diet only exercise only diet and exercise
men 0.14 0.56 0.30
women 0.44 0.36 0.20
c.
diet only exercise only diet and exercise
men 0.24 0.61 0.60
women 0.76 0.39 0.40
d.
diet only exercise only diet and exercise
men 0.16 0.54 0.30
women 0.46 0.34 0.20

Option C

Step-by-step explanation:

We want to know the percentage of women among people who only prefer exercise.

We have the following information:

                Diet Only      Exercise Only   Diet and Exercise

Men                 7                 28                           15

Women          22                   18                           10

Then we get the total of people who prefer just exercise.

Now the proportion of women who only prefer exercise is calculated as:

Therefore we must search among the options the table that shows a proportion of 39 for women who prefer only the exercise.

This table is in option C.

C.

                        Diet Only    Exercise Only         Diet and Exercise

Men                    0.24                  0.61                   0.60

Women             0.76                  0.39                   0.40

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
