Final answer:
b) 150 stamps. The approximate predicted number of stamps Katie collected in the 25th month is 150 stamps.
Step-by-step explanation:
The scatter plot shows the number of stamps Katie collected in different months. We can approximate the predicted number of stamps she collected in the 25th month by drawing a line of best fit through the points on the scatter plot. Using the line, we can determine the approximate number of stamps for a given month. To find the approximate predicted number of stamps in the 25th month, we need to find the value on the line that corresponds to the x-coordinate 25. Based on the position of the point on the line, it appears to be between 150 and 165 stamps. However, since the options provided are a) 135 stamps, b) 150 stamps, c) 165 stamps, and d) 180 stamps, the most reasonable estimate would be b) 150 stamps.
