Answer:
Step-by-step explanation:
In triangle ABC, OA = OB = OC = 10 in. These segments are radii of sircumscribed circle. So, R = 10 in.
The sum of all interio angles is 180°, so
m∠C=180°-35°-65°=80°
Use the sine theorem,
Thus,
Therefore,
Answer:
The probability that no one in a family of five will be hospitalized in a year is 0,2373
Step-by-step explanation:
Let p denote the probability of being hospitalized during a year,
Then p=0.25
And p' the probability of not being hospitalized during a year is 1-p
Thus p' = 1-p = 1-0.25 = 0.75
The probability that no one in a family of five will be hospitalized in a year is equal to . That is
=
≈ 0,2373
