Question

the average of 4, -5, -3, and 0 is 4. o true o false

Explanation:

Step1: Recall average formula

The average (arithmetic - mean) of a set of numbers $x_1,x_2,\cdots,x_n$ is $\bar{x}=\frac{x_1 + x_2+\cdots+x_n}{n}$.

Step2: Identify the numbers and $n$

Here, $x_1 = 4,x_2=-5,x_3=-3,x_4 = 0$ and $n = 4$.

Step3: Calculate the sum

$x_1+x_2+x_3+x_4=4+( - 5)+(-3)+0=4 - 5-3+0=-4$.

Step4: Calculate the average

$\bar{x}=\frac{-4}{4}=-1$.

Answer:

O False
