Since the triangle has a 30° angle and a right angle which is 90°, this triangle must be a 30 - 60 - 90 triangle, which is a triangle with special properties. The length of the leg adjacent to the 30° angle is equal to the √3 times x where x is the length of the angle adjacent to the 60<span>° angle. Here is a visual representation:

Step-by-step explanation:
3/15 simplifies to 1/5
The first equation has no solution
The picture shows all the work I did, the reason I took a pic is because it is a little hard to explain by text, but I hope this helped you!
In my opinion I would use the mean. But the options that are given I would choose answer A. But I'm not 100% sure.
Answer: 0.2401
Step-by-step explanation:
The binomial distribution formula is given by :-

where P(x) is the probability of x successes out of n trials, p is the probability of success on a particular trial.
Given : The probability that a randomly chosen citizen-entity of Cygnus is of pension age† is approximately: p =0.7.
Number of trials : n= 4
Now, the required probability will be :

Thus, the probability that, in a randomly selected sample of four citizen-entities, all of them are of pension age =0.2401
