Answer:
51.96 mm
Step-by-step explanation:
Perimeter of circle = 2 × pi × r
Perimeter of small circle
= 2 × 3.14 × 10/2
= 31.4 mm
half of perimeter of small circle = 31.4/2 = 15.7 mm
Perimeter of large circle
= 2 × 3.14 × (5+4)
= 2 × 3.14 × 9
= 56.52
half of perimeter of large circle = 56.52/2 = 28.26 mm
All line = half line small circle + half line large circle + (4 × 2)
All line = 15.7 + 28.26 + 8
= 51.96 mm

Answer:
The expected number of interviews is 3.25.
Step-by-step explanation:
For each person applying for a profissional position, there are only two possible outcomes. Either they land an interview, or they do not. The probability of a person landing an interview is independent of any other person. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:

In this problem, we have that:

So

The expected number of interviews is 3.25.
