saul85 [17]

Answer:

There are 9 boys and 12 girls in mrs Clark's class

Step-by-step explanation:

We are given that mrs Clark has 21 students, of which 3/7 are boys

In order to find the number of boys, we multiply 21 by 3/7 which results in 9

This means there are 9 boys and then we just simply subtract 9 from 21 in order to find the number of girls 21-9=12

therefore there are 9 boys and 12 girls in mrs Clark's class

The mean length of 7 planks of wood is 1.35m. When an extra plank of wood is added, the mean length of a plank of wood increase
azamat

Answer: Hello There!................

Mean = Sum of observation / total number of observation

Mean = 1.35m

1.35  = Sum of length of 7 wood planks/ 7

1.35*7 = Sum of the length of 7 wood planks

9.45 = Sum of the length of 7 wood planks

Let the length of extra added wood plank = x

So,

(Sum of the length of 7 wood planks + x) / 8 = 1.4m

(9.45 + x) / 8 = 1.4

9.45 + x = 1.4 * 8

9.45 + x = 11.2

x = 11.2- 9.45

= 1.75

So,

The length of extra added wood plank = 1.75m

Step-by-step explanation:

Mark me brainest please. Hope this helps. Anna ♥
