Mr. robinson has 20 students in his martial arts class. the ratio of boys to girls is 4: 1. how many boys and girls are in mr. robinson's class?
a. 15 boys, 5 girls
b. 5 boys, 15 girls
c. 16 boys, 4 girls
d. 4 boys, 16 girls
which of the following equations is an example of the distributive property?
a. (5)(3) = (3)(5)
b. 5+3 = 3+5
c. (5)(1+2) = (5)(1) + (5)(2)
d. 15=15

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

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
