Answer:

<u>(B)</u> Dave guessed 0.14. The law of large numbers states that as the number of trials increases the experimental probability approaches the theoretical probability. He determined the theoretical probability would be 5 36 . With 250 trials he could use the law of large numbers and expect the experimental probability to be near there.

3. Solve this inequality: 1/4-8 < 4.

juin [17]

Answer:

$j \: < \: 48$

Step-by-step explanation:

We want to solve the inequality

$\frac{1}{4}j - 8 \: < \: 4$

We add 8 to both sides to get:

$\frac{1}{4}j \: < \: 4 + 8$

$\frac{1}{4} j \: < \: 12$

Multiply both sides by 4 to get:

$j \: < \: 12 \times 4$

$j \: < \: 48$
