Question

aaden’s math teacher said that each question answered correctly on a test would be worth 5 points. answer the questions below regarding the relationship between the number of questions correct and the score on the test.
answer attempt 1 out of 5
the independent variable ( x ) represents the, and the dependent variable is the, because the depends on the.
a function relating these variables is ( v(x) = square ).
so ( v(13) = square ), meaning 13

Explanation:

Step1: Identify Variables

The independent variable \( x \) represents the number of questions correct (since it's the input we can control or change). The dependent variable is the score on the test (since it depends on how many questions are correct).

Step2: Define the Function

Each correct question is worth 5 points, so the score \( V(x) \) is 5 times the number of correct questions \( x \). So the function is \( V(x) = 5x \).

Step3: Evaluate \( V(13) \)

Substitute \( x = 13 \) into the function: \( V(13) = 5 \times 13 = 65 \).

Answer:

• The independent variable \( x \) represents the number of questions correct, and the dependent variable is the score on the test, because the score on the test depends on the number of questions correct.
• A function relating these variables is \( V(x) = \boldsymbol{5x} \).
• So \( V(13) = \boldsymbol{65} \), meaning 13 correct questions would result in a score of 65.
