Answer:

1/12

Step-by-step explanation:

The probability of just picking up a 1 is 1/4 since there is only one 1 out of 4 total cards.

If you eliminate that 1 card, there are 3 cards left, and the probability of then picking a 4 becomes 1/3.

Multiplying these probabilities, we get 1/4 * 1/3 = 1/12 as the probability of picking up a 1, not returning it, and then picking a 4 afterward.

antoniya [11.8K]

Given:

Terri plans to charge a base fee of $10 plus $7 per hour for babysitting.

To find:

The function that could be used to represent her total charge for the babysitting service, y, as a function of the number of hours she babysits, x.

Solution:

Let y be the total charge for the babysitting service for x hours.

Base fee = $10

Additional fee for one hour = $7

Additional fee for x hour = $7x

Total fee = Base fee + Additional fee for x hours

$y=10+7x$

Therefore, the equation of required function is $y=10+7x$ .

The difference of a number and eight is separate from being multiplied by 2 which is why you would use parenthesis.
