Find the mean of the numbers 20, 30, 40, 10
Write the following statement as an equation: The sum of 5 times y and 9 is 16.
Check whether the value given in the bracket is a solution of the given equation: P + 6 = 12, (P = 6),

Answer 1

Answer:

1. 5,6,7,8,9,10,11

5,6,7 8 9, 10, 11

= 8 ans

2. 20,30,40,10

MEAN = SUM OF THE OBSERVATIONS/NO. OF OBSERVATIONS

MEAN= 20+30+40+10/4

MEAN= 100/4

MEAN= 25 ans

3. 5y+9=16

4. P+6=12. {p=6}

6+6=12

12=12

Hence, verified
