6. In a game of chance, a contestant must choose a number from one of three categories. Correct number choices in Category A are
worth $1500, but there is a penalty of S1000 for each incorrect choice. Correct number choices in Category B are worth $1000,
with a $500 penalty for each incorrect choice Correct number choices in Category C are worth $500, with no penalty for an
incorrect choice. The probability of choosing correctly is 0.05 for Category A, 0.15 for Category B, and 0.25 for Category C. Which
category has the highest expected value?

15 units use socratic

step-by-step explanation: 15 units

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b

$119.20

step-by-step explanation:

$372.50 - 60% off is $149. $149-20% off is $119.20

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
