Question

the function ( f(x)=0.39x + 26.3 ) represents the line that best fits the data in the graph.
average weight and height
ages 2 through 12
jeans actual weight is 62 pounds, and her actual height is 51 inches tall. what is the difference, in inches, between jeans actual height and her height as predicted by the function? round your answer to the nearest hundredth. answer:
your answer

Explanation:

Step1: Calculate predicted height

Substitute \(x = 62\) into \(f(x)=0.39x + 26.3\).
\(f(62)=0.39\times62+26.3\)
First, calculate \(0.39\times62 = 24.18\).
Then, \(24.18+26.3=50.48\).

Step2: Calculate the difference

The actual height is \(51\) inches. The difference \(d=\vert51 - 50.48\vert\).
\(d = 51-50.48=0.52\)

Answer:

\(0.52\)
