In a certain math class, it is known that 18 students LOVE math review, and 5 students dislike math review. The teacher randomly selects three students from the class. What is the probability that all three students love math review?

Answers

The probability that the first random choice will be a matho-file and not a -phobe is 18/23. The probability of the second one is 17/22, and for the third one it's 16/21. The probability of all 3 is 4,896/10,626 = (18x17x16)/(23x22x21). That's 46.1% (rounded).

6%
D

D. plan D

Answers

Plan D will allow Maya to earn the most money in a month. Since the total salary is the sum of the basic salary and the commissionrate.

Given data:

It is given that,

Maya usually has monthly sales of about $5000

The plan is given with a monthly base salary and commission rate

Calculating for the best plan:

Option (A):

base salary = $500

commission rate = 8%

Total salary = basic salary + commission rate

                   = 500 + 5000 × 8%

                   = 500 + 400

                   = 900

Option (B):

base salary = $600

commission rate = 7%

Total salary = basic salary + commission rate

                   = 600 + 5000 × 7%

                   = 600 + 350

                   = 950

Option (C):

base salary = $700

commission rate = 6%

Total salary = basic salary + commission rate

                   = 700 + 5000 × 6%

                   = 700 + 300

                   = 1000

Option (D):

base salary = $800

commission rate = 5%

Total salary = basic salary + commission rate

                   = 800 + 5000 × 8%

                   = 800 + 250

                   = 1050

Therefore, plan (D) allows Maya to earn the most money in a month.

All 60 students in the seventh grade must choose a Fall sport in which they will participate. 1/5 of them choose volleyball, 40% of them choose soccer, and the remainder choose softball. How many students choose softball?

Answers

1/5 = 20%
100%-40%-20%=40%
40% chose softball
40% of 60:
60 x 0.4= 24 students chose softball
If my math is correct, 1/5 of 60 is 12, and 40% of 60 (which is the same as 2/5) is 24, so 12 + 24 = 36. That takes care of how many students played volleyball and soccer, so 60 - 36 = 24.
24 students chose softball.
Hope this helps!
