Question

The Mean if 8 number is 25. What is the new mean if 5 is subtracted from each number.​

Answer 1

Answer:

20

Step-by-step explanation:

mean = 25

no. of numbers = 8

total = 25*8 = 200

if 5 is subtracted from each number total no of subtractions = 8*5 = 40

total = 200 - 40 = 160

new mean = 160/8 = 20

pls mark as brainliest

Answer 2

New mean = old mean - no subtract from each no = 25-5= 20

other ,

sum of all no = 25×8= 200

sum of total diveded no = 5×8=40

reaming = 200-40= 160

mean= 160÷ 8 = 20 Ans
