Answer:
(9/34)√34 ≈ 1.543
Step-by-step explanation:
The second equation can be rewritten as ...
6x -10y -12 = 0
3x -5y -6 = 0
3x -5y = 6
__
The formula for the distance from point (x, y) to line ax+by+c=0 is ...
d = |ax+by+c|/√(a²+b²)
Then the distance from a point to the first line is ...
d = |3x -5y +3|/√(3² +(-5)²)
We know from the rearrangement of the second equation that points on its line satisfy (3x-5y) = 6. Substituting this value for (3x -5y) in the distance formula gives ...
d = |6 +3|/√34
Simplifying and rationalizing the denominator gives a distance of ...
d = (9/34)√34 ≈ 1.543
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
