Eighteen students passed the Science Test. If 18 students is 72% of the total number of students in the class, how many students are in the class?

Answers

Answer:

There are 25 students in the class.

Step-by-step explanation:

Let the total number of students in the class= x

No. of students who passed the test = 18 = 72% of x = 72x/100

Therefore, 72x/100=18

=72x=18*100=1800

=x=1800/72= 25 students.

Hence, total number of students in the class= 25 students

d. 23/38

Answers

Answer: D 23/38

Step-by-step explanation:

Probability helps us to know the chances of an event occurring. The correct option is D, 23/38.

What is Probability?

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

The value of P(C|N) is the ratio of the number of cats taking naps between 2:00 p.m and 2:30 p.m and the total number of cats.

Therefore, the value of P(C|N) is,

P(C|N) = P(C∩N)/P(C)

P(C|N) = 23/38
