Answer:  

The correct option is D. 9/38x9/38 =81/1444

Step-by-step explanation:

Total number of marbles in the bag = 38

Number of white marbles in the bag = 14

Number of gray marbles in the bag = 9

Number of blue marbles in the bag = 15

We need to find the probability that Jane takes out a gray marble in both draws

\text{Probability that Jane draws gray marble in first draw = }\frac{9}{38}

Given that : Then Jane replaces the marble for the second draw

\text{Probability that Jane draws gray marble in second draw = }\frac{9}{38}

\text{Probability that Jane draws gray marble in both draws = }\frac{9}{38}\times \frac{9}{38}

\text{Probability that Jane draws gray marble in both draws = }\frac{81}{1444}

Therefore, The correct option is D. 9/38x9/38 =81/1444

vampirchik [111]

Answer:

Step-by-step explanation:

The domain of a function is the set of values that satisfies the independent variable while the range of the function is the set of values that satisfies the dependent variable.

Since for each game, the amount of money that the Duke Blue Devils’ athletic program brings in as revenue is a function of the number of people in attendance, then the dependent variable is the amount of money while the independent variable is the number of people. The domain is between 0 and 9460 people. Therefore, the domain of this function is

0 ≤ x ≤ 9460

Where x represents number of people.

For the range, the lowest total sales is 0 × 45.5 = $0

The highest total sales is

9460 × 45.5 = $430430

The range is

0 ≤ y ≤ 430430

Where y represents total sales
