BaLLatris [955]

Answer:

54% of the students from the high school go on to college

Step-by-step explanation:

We have these following percentages:

30% of the students from a high school face a disciplinary action of some kind before they graduate. Of those, 40% go on to college.

70% do not face action, and of those, 60% go to college.

What percent of the students from the high school go on to college?

Sum of 40% of 30%(face disciplinary action) and 70% of 60%(do not

face disciplinary action). So

0.4*0.3 + 0.7*0.6 = 0.12 + 0.42 = 0.54

54% of the students from the high school go on to college

Neporo4naja [7]

Answer:

C

Step-by-step explanation:

The amount Adam invested in a six years CD was $12,000 was 7.1%

Adam made a withdrawal of $2500 early. The early withdrawal was worth eighteen months of interest on the amount withdrawn.

Monthly interest = 7.1% / 12

= 0.59%

The interest for 18 months will be

(7.1% /12)18

= 10.65%

The penalty for withdrawing early was 18 months worth the interest on the amount withdrawn

= 2500 * 10.65%

= 266.25

This means Adam needs to pay a penalty of $266.25 for withdrawing early
