17.3 is ten times as much as 1.73.
Answer:
(a) 0.42
(b) 0.28
(c) 0.88
Step-by-step explanation:
Let probability that the bank stock will appreciate over a year, P(A) = 0.70
Probability that the electric utility will increase over the same period, P(B) = 0.60
Also, it is given that the two events are independent.
(a) Probability that both stocks appreciate during the period = Bank stock will appreciate * Electric utility will appreciate = P(A) * P(B)
= 0.70 * 0.60 = 0.42 .
(b) Probability that the bank stock appreciates but the utility does not is given by;
P(A) * (1 - P(B)) = 0.70 * (1 - 0.60) = 0.70 * 0.40 = 0.28 .
(c) Probability that at least one of the stocks appreciates = P(A B)
P(A B) = P(A) + P(B) - P(A B)
= 0.70 + 0.60 - (0.70 * 0.60) { because both events are
independent }
= 1.3 - 0.42 = 0.88 .

Answer:
sec(x) = 1.15
Step-by-step explanation:
We can figure out what x is by using the arctan(x) function:
So, now let's figure out the cos(x) as sec(x) is equal to the reciprocal of cos(x):
Let's take the reciprocal:
And that's your answer.
