Clare is paid $90 for 18,000 seconds of work. At this rate, how many seconds does it take for her to earn 25 cents? It would take Clare seconds to earn a quarter.

50 seconds

Step-by-step explanation:

From the question, we are informed that Clare is paid $90 for 18,000 seconds of work. This means that for Clare to get $1, she'll work for (18000/90) = 200 seconds. From the calculation $1 = 200 seconds

We should note that 100 cents = $1, therefore 25 cents = 25/100 = $0.25.

The seconds that it will take for her to earn 25 cents will be:

= 200 × 0.25

= 50 seconds

Therefore, it'll take 50 seconds for her to earn 25 cent.

Probability of drawing four balls numbered 1, 4, 8, and 6 from a 8 ball bucket = 0.041667

Step-by-step explanation:

Probability is  of the ratio of number of favorable outcomes to the total number of outcomes.

Here outcome is drawing 4 balls from a 8 ball bucket.

Favorable outcome is randomly drawing four balls numbered 1, 4, 8, and 6.

Total number of ways in which 4 balls from a 8 ball bucket can be drawn is given by 8 x 7 x 6 x 5 = 1680.

Total number of ways in which drawing four balls numbered 1, 4, 8, and 6 from a 8 ball bucket is given by 8C₄

Probability of drawing four balls numbered 1, 4, 8, and 6 from a 8 ball bucket is given by

Probability of drawing four balls numbered 1, 4, 8, and 6 from a 8 ball bucket = 0.041667
