A school conducts a recipe contest in which 1 student gets first place, 1 student gets second place, 1 student gets third place,
and 10 students tie for fourth place. Fifty students enter the contest. If X represents the distribution of prizes, which graph represents the probability distribution for a randomly selected student?

Answer:
A graph of the probability distribution is attached.
Step-by-step explanation:
The probability that a student gets first place is 1/50. The probability that a student gets second place is 1/50. The probability that a student gets third place is 1/50. The probability that a student gets fourth pace is 10/50. This leaves
50-(1+1+1+10) = 50-13 = 37
students that do not place.

The ratio of Claire's songs to her mother's songs = 3 : 2
A.
3 : 2 = 3/2
9 : 6 = 9/6 = 3/2
12 : 10 = 12/10 = 6/5
B.
3 : 2 = 3/2
6 : 4 = 6/4 = 3/2
15 : 10 = 15/10 = 3/2
C.
3 : 2 = 3/2
4 : 3 = 4/3
5 : 4 = 5/4
D.
3 : 2 = 3/2
4 : 6 = 4/6 = 2/3
20 : 30 = 20/30 = 2/3
The table which shows the correct ratio and two equivalent ratios is B
