A 500-foot weather
1 answer:
<h3>Answer: 293 feet</h3>
==========================================
Explanation:
See the attached image below. The information that the tower is 500 ft is never used. Focus solely on triangle ABD (ignore point C).
AB = 200
AD = x = unknown
angle ABD = angle B = 47 degrees
Use the cosine rule to help find x
---------
cos(angle) = adjacent/hypotenuse
cos(B) = AB/BD
cos(47) = 200/x
x*cos(47) = 200
x = 200/cos(47)
x = 293.255837127926
Rounding to the nearest foot, we get 293 feet as the answer.

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").
