Question

true or false: the average of the numbers 8 and 9 is 8r1. true false

Explanation:

Step1: Calculate the average

The formula for the average (arithmetic mean) of two numbers \(a\) and \(b\) is \(\frac{a + b}{2}\). For \(a = 8\) and \(b = 9\), we have \(\frac{8+9}{2}=\frac{17}{2} = 8.5\).

Step2: Compare with 8R1

The notation "8R1" typically represents a division with remainder, where 8 is the quotient and 1 is the remainder (e.g., in \(17\div2\), we get \(8\) with a remainder of \(1\), but this is not the average). The average is a decimal (or fraction) value, not a remainder - based expression in the context of finding the mean. So the statement is false.

Answer:

False
