total 172 268 440
of the total people surveyed, what is the relative frequency of 10-19 year olds who preferred to ski?

2.73%
6.98%
12%
44.44%

6.98%

Step-by-step explanation:

To find relative frequency we divide frequency with the total number participants in that age bracket

Total number of participants age 10-19=172given in the table

The frequence for those who ski at age 10-19=12given in table

Relative frequency= 12/172 = 0.0697

Expressed as a percentage= 0.06976×100 =6.98%

The correct answer option is 6.98%.

Step-by-step explanation:

We are given the results of a survey which asked  two age groups which summer sport they most preferred.

We are to find the relative frequency of 10-19 year old who preferred to ski.

For that, we will divide the number of kids aged 10-19 years who prefer to ski by the total number of people who prefer to ski and multiply by 100.

Relative frequency = 12/172 * 100 = 6.98%

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet
