Question

find the mean of first ten multiples of 5​

Answer 1

Answer:

first 10 multiples of 5 are 5 10 15 20 25 30 35 4045 50

Step-by-step explanation:

the sum of all these numbers are 275 and forgetting the mean of first 10 multiples of 5 we have to just divide the 275 by the number of observations like 10 in this question

Answer 2

Answer:

Mean of first ten multiples of 5(x)= 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

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

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
