Answer:
the probability having no customers are in the system is 0.375
Step-by-step explanation:
The computation of the probability having no customers are in the system is as follows;
Given that the arrival rate is 1.25 customers per minute
The Service rate is 2 customers per minute
Based on the above information, the probability is

Hence, the probability having no customers are in the system is 0.375

Answer:
Step-by-step explanation:
Let's solve 2x^2 = -X^2 - 5x - 1. Consolidate all terms on the left side and write 0 on the right side:
3x^2 + 5x + 1 = 0. This is a quadratic equation. Let's solve it for x using the quadratic formula:
a = 3, b = 5, c = 1, and so the discriminant is b^2 - 4ac = 5^2 - 4(3)(1) = 13. Because the discriminant is positive, we know that there are two distinct, real roots; the graphs of y = 2x^2 and y = x^2 - 5x - 1 intersect in two places whose x-coordinates are the real roots mentioned above.
Answer A is not correct as stated, but would be correct if we were to replace "the y-coordinates" with "the x-coordinates."
Answer C would be correct if and only if we write y = x^2 - 5x - 1.
The range is the output or the y values in the case of this function. The only y value on this function is 1 therefore the range is 1
