Answer:

Step-by-step explanation:

Substitute 8 for x

3(8) - 1

Solve:

3 x 8 = 24

24 - 1 = 23

Next, substitute for x in the inequality with the answer you just made. See if it's true.

23 \leq 2

The inequality is NOT TRUE

Same thing for the next one

1/2(8) + 5

Solve:

1/2 x 8 = 4

4 + 5 = 9

Substitute for x in the inequality with the answer you just made. See if it's true.

9 > 2

This inequality is TRUE

Hope this helps!!!

A die is rolled and the results are 1, 2, 1, 4, 5, 6, 1, 3, 6, 6, 5, 2, 3.
ANTONII [103]
<h3>Answer: True</h3>

We have A = 2 copies of "2" showing up out of B = 13 rolls total

A/B = 2/13 = 0.1538 is the experimental probability of rolling a 2

Compare this with 1/6 which is the theoretical probability of rolling a 2 (since there is one side labeled "2" out of 6 sides total)

1/6 = 0.167 approximately

Comparing 0.1538 with 0.167 is fairly close

or you could argue that 2/13 is close to 2/12 = 1/6
