Answer:
2nd and 4th are correct
Step-by-step explanation:
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: The team won 47 games.
Step-by-step explanation: The total games played was 84, and that means all games added together, but victories and losses. If the games they lost is called X, and the team won 10 more games than it lost, then it means the games they won is X + 10.
To find the value of wins and losses, we can now express both properly as;
X + (X +10) = 84
2X + 10 = 84
Subtract 10 from both sides of the equation
2X = 74
Divide both sides of the equation by 2
X = 37.
If the number of games won is X + 10, then games won is derived as
Wins = X + 10
Wins = 37 + 10
Wins = 47
The team won 47 games
The answer is attachment 3 Because the y intercept is -5 and it goes down three and to the left 4.
