Answer:
5/8
Step-by-step explanation:
First we need to figure out how many girls and boys there are.
g = girls
b = boys
g = b+8 ( eight more girls than boys)
b = g-8
There are 32 students)
g+b =32
Substitute b = g-8 into the equation
g + (g-8) = 32
Combine like terms.
2g-8 = 32
Add 8 to each side.
2g -8+8 = 32+ 8
2g = 40
Divide by 2
g = 20
There are 20 girls
The experimental probability of picking a girl is
girls/ total
20/32 = 5/8
Answer:
b. the triangle is not a right triangle
Step-by-step explanation:
Answer:
Let the two angles be x and 2x
Sum of angles of triangle=180°
60+x+2x=180
3x=180-60
x=120/3
x=40
2x=80
Step-by-step explanation:
40 and 80 are other two angles
