If three arthmethic means are are inserted between -15 and 9,find the first of these arthmetic means.

- 9

Step-by-step explanation:

We require

- 15 , m₁, m₂, m₃, 9

The average of the end values gives m₂ , that is

m₂ = = = - 3

Similarly, the average of - 15 and m₂ gives m₁

m₁ = = = - 9

The first arithmetic mean m₁ = - 9

its 8

step-by-step explanation:

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
