Answer:

10:40

Step-by-step explanation:

Step 1: Reduce ratio to lowest value

3 : 12 = 1 : 4

<em>*Divide by </em>3

Step 2: Solve ratio

<em>Let 'x' represent the second number </em>

1 : 4 = 10 : x

<em>Multiple the left side by 10</em>

10 : 40 = 10 : x

Therefore the second number in the ratio with 10 is 40

IRINA_888 [86]

Answer:

Given that a car is a coupe, there is a 10% chance it is from the previous model year.

Step-by-step explanation:

The consideration "Given that a car is from the previous model year, there is a 10% chance that it is a coupe." wouldn't give much information. Previous year models are 10% Coupe and 25% Sedan.

Same for consideration "There is a 10% chance that the car is from the previous model year." This consideration would be good if only a specific model would be taken.

Consideration "There is a 10% chance that the car is a coupe." makes no sense because, in order for this to be true, 90% of specific models would be a sedan which table clearly shows 25%.
