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
In order to solve for both x and y, we need to use the substitution property, where we replace a variable with what we solved for.
Let's solve for y first. Equation (1st one): 8x + 4y = 12. To isolate y, we can first subtract 8x from both sides, and then divide all terms by 4.
Then, we can solve for x. Let's take the second equation: 3x + y = 3. We take what we solved for in the previous step and plug it into this equation.
Both equations are also the same, so the solution = all real numbers for x.

Answer:
Step-by-step explanation:
The domain is the set of numbers for which a functipn is defined and a gtaph exist. In this case the domain begins at -2 and ends at 1.
"All real numbers greater than or equal to -2 but less than 1."
Answer:
<P = 56 degrees
Step-by-step explanation:
Given the following
m<R = 90 degrees
QR = 61feet = Adjacent
RP = 90 feet= Opposite
Required
tan<P = opp/adj
Tan<P = 90/61
<P = arc tan (90/61)
<P = arctan 1.4754
<P = 55.9
<P = 56 degrees to the nearest degree
