The sinusoid makes a complete oscillation (i.e. 360°) every 3 seconds. So, in one second it makes 1/3 of a turn, leading to 360°/3 = 120°.
So, the correct answer is the last one.
Answer:
a) 0.5514
b) 0.0058
Step-by-step explanation:
Data provided in the question:
Probability that the the selected person is righthanded, P(R) = 0.82
Therefore,
Probability that the the selected person is not righthanded, P(R') = 1 - 0.82
= 0.18
Now,
a. They are all right-handed
P (They are all right-handed) = P(R) × P(R) × P(R)
= 0.82 × 0.82 × 0.82
= 0.5514
b) None of them is right-handed
P (None of them is right-handed) = P(R') × P(R') × P(R')
= 0.18 × 0.18 × 0.18
= 0.0058

Answer: The price for the adult tickets is $12 and the price for the child ticket is $5.
Step-by-step explanation:
Let the price for the adult ticket be x
Let the price for the child ticket be y
According to question, On Friday ,
and on next day,
Now, we will use "Substitution Method" to solve the system of equations :
so, we will put the value of x in the first equation i.e.
Now, put the value of y in the equation that is given by
Hence, the price for the adult tickets is $12 and the price for the child ticket is $5.
