The probability that a student is in seventh grade, given that he/she is dropped off by parents is <u>option C)</u> 0.22
<u>Step-by-step explanation</u>:
- The total probability of students in 7th grade = 0.56
- The probability of 7th grade students dropped by parents = 0.12
P(student is in 7th grade student is in seventh grade) = P(students in 7th grade) / P(7th grade students dropped by parents).
⇒ 0.12/0.56
⇒ 0.22

Answer:
Step-by-step explanation:
Pythagorean Theorem:
500^2 = 300^2 + x^2
250,000 = 90,000 + x^2
160,000 = x^2
x = +/- 400 use the positive root
height is 400ft
If you're on about us tons then it = 20
However if it's tonnes then it = 18.143695
