Question

What is the A.M of x-3 and x+5

Answer 1

Answer:

$first \: number = x - 3 \\ \\ \\second \: number = x + 5$

✦$arithmetic\:mean = \dfrac{a + b}{2}$

$\implies \frac{x - 3 + x + 5}{2} \\ \\ \\ \implies \frac{2x + 2}{2}\\\\\\\implies\frac{2(x+1)}{2}\\\\\\\implies\:x+1$

Answer 2

Answer:

A.M of  x-3 and x+5 is x+1.

Step-by-step explanation:

Arithmetic Mean:

• The arithmetic mean is calculated by dividing the total of a set of numbers by their count, which captures the collection's central tendency.
• Because it might be biased by outliers, the arithmetic mean is not always able to accurately pinpoint the "location" of a data set.
• The arithmetic mean is appropriate in finance to support projections.    

Given two values are

    x-3 and x+5

 Finding the Arithmetic mean:  

   The Arithmetic mean A.M of two numbers a and b is given by (a+b)/2.

 Let us suppose a = x-3  and b = x+5

     A.M of a and b =  (a+b)/2

                               = (x-3+x+5)/2

                               = (2x+2)/2

                               = [2(x+1])/2

                               = x+1

    Hence, A.M of  x-3 and x+5 is x+1.
