36 girls, 58 boys and 356 adults are members of a tennis club. 50 more children join the club. the number of girls is now 12% of the total number of members. How many of the 50 children were boys?​

36 + 58 + 356 = 450

450 + 50 = 500

0.12 × 500 = 60

500 − 60 + 356 = 84

84 − 58 = 26 boys out of 50

Step-by-step explanation:

26 of the 50 children were boys

Step-by-step explanation:

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
