Question

1. the school counselor keeps a candy jar in her office for students. during one week, she kept count of how many students came to visit her and the number of candies in the jar, as shown in the scatter plot. based on the trend line, what is the best prediction for the number of candies in the jar when 30 students visit her? a. 90 b. 150 c. 135 d. 180

Explanation:

Step1: Locate \(x = 30\) on the scatter - plot

We are interested in predicting the number of candies when the number of students (\(x\)) is \(30\).

Step2: Find the corresponding \(y\) - value on the trend line

On the scatter - plot, when we move vertically from \(x = 30\) (number of students) to the trend line and then horizontally to the \(y\) - axis (number of candies in the jar), we observe that the value is closest to \(135\).

Answer:

C. 135
