In a class of 32 students

Mathematics
1 answer:
DerKrebs [107]3 years ago

Answer:

1.48 m.

Step-by-step explanation:

The number of girls in the class = 32 - 14 = 18 girls.

Sum of the boy's heights = 14 * 1.56 = 21.84 m.

Sum of all the student's heights = 32 * 1.515 = 48.48 m.

So the sum of the heights of the girls is 48.48 - 21.84

= 26.64 m.

So the mean height of the girls 26.64 / 18

= 1.48 m.

Keith_Richards [23]

Answer:

12

Step-by-step explanation:

The ratio of cars to trucks to motorcycles is $4:3:2.

If there are $42$ cars and trucks total,

To get how many motorcycles are there

Sum up the ratio of cars and trucks 4:3= 4+3 = 7

Sum up the ratio of cars and trucks and motorcycles

4+3+2 =9

Let the total number of cars and trucks and motorcycles be represented as A

The total number of cars and trucks in the question is 42

(7/9) x A = 42

7A/9 = 42

cross multiply

7A = 42×9 = 378

A= 378/7 = 54

The total number of cars and trucks and motorcycles is 54

To get the number of motorcycles can be calculated through

a. The total number of cars and trucks and motorcycles subtracted by the number of cars and trucks = 54-42=12 or use the ratio which is

2/9 × 54 = 2×6=12
