Answer:
Option C) 0.1804
Step-by-step explanation:
We are given the following information in the question:
Mean customers enter the tellers’ queue every five minutes = 2
Thus, the number of customers that enter the tellers’ queue is Poisson distributed
Formula:
We have to evaluate:
0.1804 is the probability that exactly three customers enter the queue in a randomly selected five-minute period.
Thus, the correct answer is
Option C) 0.1804
Answer:
23.4 years.
Step-by-step explanation:
7400 dollars is placed in an account with an annual interest rate of 7%.
Now, let us assume that the interest is compounded annually and it will take x years for account value to reach 36000 dollars.
Hence, from the formula of compound interest, we can write that
⇒
Taking ln both sides we get,
x ln (1.07) = ln (4.865)
⇒ x = 23.4 years.
<span>Simplifying
f(x) = 3x + -14
Multiply f * x
fx = 3x + -14
Reorder the terms:
fx = -14 + 3x
Solving
fx = -14 + 3x
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'x'.
f = -14x-1 + 3
Simplifying
f = -14x-1 + 3
Reorder the terms:
f = 3 + -14x<span>-1</span></span>
