Answer:

160 times in 300 trials

Step-by-step explanation:

Since the spinner has 5 sections numbered 1 through 5, there are 2 even numbers (2 and 4) and 3 odd numbers (1, 3, and 5).

From the given dot plot, we can see that Melanie landed on an even number 8 times out of 15 spins.

To predict the number of times the spinner will land on an even number in 300 trials, we can use proportion:

8/15 = x/300

Multiplying both sides by 300, we get:

x = 160

Therefore, we can predict that the spinner will land on an even number approximately 160 times in 300 trials.
