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:
c) bajo: $1.62; mediano: $1.80; grande: $2.03
Step-by-step explanation:
Insert numbers from the table into a linear equation (ignore time column) and use Cramer's Rule.
55x+53y+54z=299.12
17x+22y+25z=117.89
30x+23y+29z=148.97
x, bajo = 1.62
y, mediano = 1.8
z, grande = 2.03
Answer:
15 feet, 7.5 square feet
Step-by-step explanation:
Perimeter = 6.5 + 2.5 + 6
= 15 feet
Area = ½ × 2.5 × 6
= 7.5 feet²
Answer: each guest gets 4.19 cm²
Step-by-step explanation:
The cake is a circle. The area which he cuts for himself is a sector with a central angle of 120 degrees. The formula for determining the area of a sector is expressed as
Area of sector = θ/360 × πr²
Where
θ represents the central angle
π is a constant whose value is 3.14
r represents the radius of the circle.
From the diagram,
r = 4cm
Therefore, area of the cake that he cut for himself is
120/360 × 3.14 × 4²
= 16.75 cm²
The total area of the cake is
3.14 × 4² = 50.24 cm²
Therefore, the rest of the cake is
50.24 - 16.75 = 33.49 cm²
The amount that each guest gets would be
33.49/8 = 4.19 cm²
