Question

10 fill in the blank 1 point n weighted average what is the weighted average of the numbers - 2 and 22 with weight 4/5 on the first number and 1/5 on the second number? weighted average = type your answer...

Explanation:

Step1: Calculate the weighted value of the first number

Multiply the first number \(-2\) by its weight \(\frac{4}{5}\): \(-2\times\frac{4}{5}=-\frac{8}{5}=- 1.6\)

Step2: Calculate the weighted value of the second number

Multiply the second number \(22\) by its weight \(\frac{1}{5}\): \(22\times\frac{1}{5}=\frac{22}{5} = 4.4\)

Step3: Sum the weighted values

Add the two weighted values together: \(-1.6 + 4.4=2.8\)

Answer:

\(2.8\)
