Question

find the mean of first 10 multiples of 5.

Answer 1

the multiples of 5 are 5,10,15,20,25,30,35,40,45,50
the mean is = sum of multiples/ number of multiples
therefore, 5+10+15+20+25+30+35+40+45+50 / 10
= 275 / 10
= 27.5

Answer 2

Answer:

Mean of first 10 multiples of 5 is 27.5

Step-by-step explanation:

Step 1:

Given Data:  

To Find the Mean of first ten multiples of 5:

Step 2:

Mean of first ten multiples of 5 = Sum of observations/ number. Of observations

Step 3:

= (5+10+15+20+25+30+35+40+45+50)/10

Step 4:

Sum of observations=275

Number of observations=10

Sum of observations/ number. Of observations = 275/10  = 27.5

Mean of first ten multiples of 5(x)= 27.5
