Requests for service in a queuing model follow a Poisson distribution with a mean of 5 per unit time. a) What is the probability that the time until the first request is less than 4 time units?

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

113.1

step-by-step explanation:

v=4

3πr3=4

3·π·33≈113.09734

60: 45 =12: 9 =4: 3 so the answer is 4: 3
