Answer 1

Answer:

hey here is your answer -

Step-by-step explanation:

as this is an average finding question

then , formula for finding mean = numbers / frequency

so , class no. = 0-20 20-40 40-60 60-80 80-100 = -100 by solving

and frequency = 3+4+5+7+6 = 25 by solving

now using formula for mean = numbers / frequency

= -100 / 25

= -4 ans.

so -4 is your answer
