Answer:
Step-by-step explanation:
The probability that a randomly selected student is in music/drama is 25%
<h3>How to determine the probability?</h3>
From the table, we have the following values
Music/Drama = 7 + 13 + 5 = 25
Total = (20 + 20 + 25 + 7 + 13 + 5 + 3 + 2 + 5) = 100
The probability is then calculated as:
P = Music/Drama / Total
So, we have:
P = 25/100
Express as percentage
P = 25%
Hence, the probability that a randomly selected student is in music/drama is 25%

Answer:
x = 8
Step-by-step explanation:
9x = 72
x = 72 ÷ 9
x = 8
1/3 h - 8/3 h + 12 = 2/3 h - 6
-7/3 h + 12 = 2/3 h - 6
-9/3 h = - 18
-3 h = -18
h = 18/3 = 6
