Birth weights (grams)

Work out the number of mice with birth weights below 10 g.

The answer is "80 mice"

Step-by-step explanation:

In the given question, the attachment is missing, that is attached with the answer.

Formula:

When range in between 6-10 So,

base =4

height= 3

area = 4×3 =12  

When range in between 10-12 So,

base =2

height= 8

area = 2 × 8 =16

When range in between 12-14 So,

base =2

height= 11

area = 2 × 11 = 22

When range in between 14-15 So,

base =1

height= 23

area = 1 × 23 =23

When range in between 15-16 So,

base =1

height= 19

area = 1 × 19 =19

When range in between 16-20 So,

base =4

height= 2

area = 4 × 2 =8

Formula:

weight which below from 10 g  =  

weight = 80 mice

2

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
