lity of ms guerra picking a girl? express your answer as a fraction in simplest form.
1 answer:
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

After you minus the numbers you simplify them and get 1 and 7/10
Answer: 15x - 12
Steps: 3 (5x - 4)
3 x 5x - 3 x 4
15x - 3 x 4
15x - 12
Y=Ф + 8/(ФcosФ) ==> note that
dy/dФ = 1 - 8/[(ФcosФ)]² x (-8sinФ) ==> dy/dФ = 1+[(64sinФ)/Фcos²Ф]
==> dy/dФ = 1+ 64tanФ/Ф or dy/dФ = (Ф+tanФ)/Ф
