x = 22 → A
Answer:
9 + 10 = 19
1 + 2 = 3
Step-by-step explanation:
To add 2 to 1, look at a number line and start at the point 1 and go two numbers to the right to end at 3.
This relative frequency is an experimental probability: that of getting a red on a spinner. In 300 spins, we'd expect to get 0.4(300), or 120, reds.
