Question

A. Independent Activity it (ure a a whole cheet of paper to answer activities A to F.) . following Directions Directions: Compute the arithmetic mean between the pairs of numbers. 475 and 615 2.) 8 and -12 8.) 7 3 and x+3 and 34 -1 5.) 285 and 6

Answer 1

ARITHMETIC MEAN is the average of the numbers.

You add it, and divide by 2.

a)

(475 + 615) /2 = 545

b)

(8 + - 12) /2

=(8-12)/2

-4/2

-2

c)

`((2)/(3)+(3)/(4))/(2)=((8+9)/(12))/(2)=((17)/(12))/(2)=(17)/(12)*(1)/(2)=(17)/(24)`

d)

`\frac{(x+3)+(3x-1)_{}}{2}=(4x+2)/(2)=(2(2x+1))/(2)=2x+1`

e)

`\frac{2\sqrt[]{5}+6}{2}=\frac{2(\sqrt[]{5}+3)}{2}=3+\sqrt[]{5}`
