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

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
