in kurt's school, the ratio of boys to girls is 4/3. of 120 students are boys, how many students are girls?

90 of the students are girls.

Step-by-step explanation:

Boys : Girls

B : G

4 : 3

120 : ?

(120 ÷ 4 = 30) so 4 × 30 = 120

(Do this to the other side) 3 × 30 = 90

B : G

120 : 90 [90 girls out of 210 total students]

Hope this helps. :)

78.59 is the mean

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
