On a soccer team, 8 out of 19 players surveyed say they had two or more siblings. the league has 570 players. which is the best prediction of the number of players in the league that have two or more siblings?

330

240

30

11

In this question the result that will come will be a predicted result and so it might not be the perfect result. Now let us concentrate on the details that are already provided in the question.
It is given that 8 out of 19 players had 2 or more siblings
Then
Percentage of players having 2 or more siblings = (8/19) * 100 Percent
                                                                              = 800/19 percent
Now assuming that the percentage does not change when surveyed among 570 players, then
Number of players having more than
 2 siblings among 570 players = [800/(19 * 100] * 570
                                                 = (800/1900) * 570
                                                 = (8/19) * 570
                                                 = 8 * 30
                                                 = 240
So it can be predicted that 240 players will have 2 or more siblings. the second option given in the question is the correct option.

J= r + 9 because since jessica rode 9 more miles than roger, you add 9 miles to rogers mileage.
