Question

the scatterplot shows how many hours students practiced karaoke during the week (x) and the scores they earned in a singing competition (y). the line of best fit is y = 6x + 37. use the equation to predict the score of a student who practiced for 5 hours. score =

Explanation:

Step1: Substitute \(x = 5\) into the equation

Given the equation \(y=6x + 37\), substitute \(x = 5\). So we get \(y=6\times5+37\).

Step2: Calculate the value of \(y\)

First, calculate \(6\times5=30\). Then, add \(37\) to it: \(y=30 + 37\).

Answer:

\(67\)
