Sue used a probability simulator to roll a 12-sided number cube 100 times. Her results are shown in the table below:

Number on the Cube Number of Times Rolled
1 14
2 12
3 10
4 5
5 16
6 5
7 8
8 18
9 2
10 5
11 2
12 3

Using Sue's simulation, what is the frequency of rolling a 2 on the number cube?
100 over 88
12 over 100
100 over 12
88 over 100

B. 12 over 100

Step-by-step explanation:

The frequency of rolling any number is the number of times you roll it / total number of times you roll the die.

She rolled the die 100 times, so the denominator is 100.

She got 2 12 times, so the numerator is 12.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
