Question

Mean of y–2a, y – a, y , y + a, y + 2a is_______.​?

Answer 1

Step-by-step explanation:

Given: y-2a, y-a, y, y+a, y+2a

Find: The mean

Solution:

Mean = Sum of observations / Number of observations

= y-2a + y-a + y + y+a + y +2a/5

Grouping the y and a together, we get:

= 5y -3a + 3a/5

= 5y + 0/5

= 5y/ 5

Mean = y

Mean of y-2a, y-a, y, y+a, y+2a is y

Answer 2

Answer:

5y

Step-by-step explanation:

y-2a+y-a+y+y+a+y+2a

all postive sign cancel to the negative sign

so, -2a+2a-a+a =0

carry is y+y+y+y+y=5y

so , this is your answer 5y
