B is the answer to the question
Answer:
<h2><em>
$23.5</em></h2>
Step-by-step explanation:
Gene is playing a game with a bag of marbles. If 3 of the marbles are blue, 4 are green, and 7 are yellow and awarded prices for the marbles are $2 green $0.5 yellow $4 blue, the expected payout for Gens game is expressed as shown;
If a blue marble costs $4, 3 blue marbles will cost 3*$4 = $12
If a green marble costs $2, 4 green marbles will cost 4*$2 = $8.0
If a yellow marble costs $0.5, 7 yellow marbles will cost 7*$0.5 = $3.5
Total payout for Gene's game will be the equivalent to $12+ $8 + $3.5 = $23.5.
<em>Hence Gene expected cost will be $21.5</em>
Answer:
<u>Population : all the steaks Tessa can cook</u>
<u>Parameter : minimum internal temperature of 160 degrees Fahrenheit</u>
<u>Sample : two random thermometer readings</u>
<u>Statistic : minimum sample reading of 165 degrees Fahrenheit</u>
Step-by-step explanation:

- Parameter is is a value that describes a characteristic of an entire population, such as the minimum temperature of the steaks Tessa is cooking in Fahrenheit degrees.
- Sample is a subset of the population, in our case, the two random readings of the thermometer Tessa did.
- Statistic is a characteristic of a sample, for our problem, it's the minimum reading of 165 degrees Fahrenheit.
