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
4/20, 20% chance. The store has 20 puppies. Out of them is 4 poodles. Divide 4 by the total(20). And you get 0.2, remove the decimal place and add it in front of the 0 .02 reverse the numbers 20. Replace the period with a %.
Answer:
45/58 it is already in simplest form
Step-by-step explanation:
The distance is 2.23606 (2.24 rounded)
Answer:
y=-3x+4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-8-7)/(4-(-1))
m=-15/(4+1)
m=-15/5
m=-3
y-y1=m(x-x1)
y-7=-3(x-(-1))
y-7=-3(x+1)
y=-3x-3+7
y=-3x+4
