Answer:
Value of a is 0.667
Step-by-step explanation:
We are given the following in the question:
The rate of customer at an airport follows a Poisson distribution with
The normal approximation of Poisson distribution can be done in the following manner
Formula:
We have to find the value of a such that
More than 50 customers per 5 hours means more than 10 customer per hour.
Thus, we can write
Therefore, value of a is 0.667
Vertex form is a(x-h)^2+k. The vertex is (h,k), and you basically take the opposite of h and you copy down k. For example, if the vertex of a parabola is represented by 2(x+2)^2-6, (-2,-6) would be the vertex. Also, the domain is the interval at which the x-values are extended, and the interval at which the y-values are extended would be the range. In order to identify these aspects of the function, work backwards to get the starting quadratic that this function was represented as. Then, if the function is just a quadratic polynomial, then a rule is that the domain and range of the function are all real numbers, as there isn't a denominator of the function to worry about (different steps will be taken for that). You can express the domain and range as two separate ordered pairs, such as domain- (how far left the function will go, how far right the function will go) and range- (how far down the function will go, how far up the function will go).
