Question

lex x represent the number of hours studied.
a model for predicted test score is: $s = 55 + 8x$
if a student studies for 6 hours, the model predicts a score of __________.

Explanation:

Step1: Identify the value of x

The student studies for 6 hours, so \( x = 6 \).

Step2: Substitute x into the formula

We have the formula \( S = 55 + 8x \). Substitute \( x = 6 \) into it: \( S = 55 + 8\times6 \).

Step3: Calculate the result

First, calculate \( 8\times6 = 48 \). Then, \( 55 + 48 = 103 \).

Answer:

103
