Answer:
There is a 0.57% probability that a randomly selected nanny who was placed during the last year is a male nanny (a "mannie").
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem, we have that:
Desired outcomes:
The number of male nannies selected. 24 of the nannies placed were men. So the number of desired outcomes is 24.
Total outcomes:
The number of nannies selected. 4,176 nannies were placed in a job in a given year. So the number of total outcomes 4176.
Find the probability that a randomly selected nanny who was placed during the last year is a male nanny (a "mannie").

There is a 0.57% probability that a randomly selected nanny who was placed during the last year is a male nanny (a "mannie").
Answer:
A
Step-by-step explanation:
Vertex appear to be at (5,115)
A) h = -b/2a
= -(20)/2(-2) = 5
k = -2(5²) + 20(5) + 60 = 110
Answer:
12.5π units²
Step-by-step explanation:
Area of a semi-circle = πr²/2
Radius = diameter/2
Radius = 5
Therefore, the area of the semi-circle = 12.5π units²
Answer:
The discriminant is equal to zero
Step-by-step explanation:
If x=6 is the only x-intercept of the graph of a quadratic equation, the it means the quadratic equation has a repeated root.
When a quadratic equation has a repeated root, it means its discriminant is zero.
This means that
