Answer:

The best estimate of the probability of getting a green marble from this bag of 50 marbles is 1/3.

Step-by-step explanation:

Andre gets 1 green marble out of 4 trials.

For Andre, the probability of getting 1 green marble is 1/4.

Jada gets 5 green marbles out of 12 trials.

For Jada, the probability of getting 1 green marble is 5/12.

Noah gets 3 green marbles out of 9 trials.

For Noah, the probability of getting 1 green marble is 3/9.

Hence, the best estimate of the probability of getting a green marble from this bag = (1/4 + 5/12 + 3/9)/3 = [(9 + 15 + 12)/36]/3 = 1/3.

There are two pizzas. Conor ate 1⁄4 of a pizza, Brandon 2⁄8, Tyler 3⁄4, and Audrey 4⁄8. Who ate the most of the two pizzas?
Semenov [28]
Not exactly sure, but just by my knowledge and common sense I'd say Tyler. He ate 3/4 so he ate most out of what was given to him.

The stock of Company A gained 2% today to $79.56. What was the opening price of the stock in the beginning of the day?
CaHeK987 [17]

Answer: $78

Step-by-step explanation:

From the question, we are informed that the stock of Company A gained 2% today to $79.56. The opening price of the stock in the beginning of the day will be calculated as:

= [100% / (100% + 2%)] × 79.56

= (100% / 102%) × 79.56

= 1/1.02 × 79.56

= 79.56/1.02

= 78

Therefore, opening price of the stock in the beginning of the day is $78
