Question

A spinner has sections that are numbered 1 through 5. Melanie spins the spinner 15 times and

records her results in the dot plot.
Use the results to predict the number of times
the spinner will land on an even number in 300 trials
300 trials.

Answer 1

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.
