Answer:
Step-by-step explanation:
a1 = 3;
a2 = 2(a1 - 2 ) = 2(3-2) = 2
a2 = 2
a3 = 2(a2-2) = 2(2-2) = 0
a3=0
a4 = 2(a3-2) = 2(0-2) = -4
a4 = -4
a5 = 2(a4 - 2) = 2(-4-2) = -12
a5 = -12
Answer: 99
Step-by-step Explanation:
Since we know the formula for the area of a triangle is b * h * 1/2, we can therefore insert our given numbers into the equation, making it 18 * 11 * 1/2. This means that our final answer is 99.
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%
