Answer:
The midpoint is (1, 4.5)
Step-by-step explanation:
To find the midpoint, take the coordinates for the two endpoints and add the x's and divide by two. Then add the y's and divide by two. R has coordinates (-4,0) and B is (6,9). On this particular question when we just do half of the problem we can pick out the correct answer from the multiple choice list. -4 + 6 is 2. And divided by 2 is
2/2 is 1 there is only one choice that has an x that is 1. It doesn't hurt, nor take much time to confirm with the y's. 0+9 is 9. And 9/2 is 4.5.
So the midpoint is (1, 4.5)
Answer:
0.018133
Step-by-step explanation:
Given that customers arrive randomly and independently at a service window, and the time between arrivals has an exponential distribution with a mean of 12 minutes.
Let X equal the number of arrivals per hour.
X is having average as reciprocal of 12 minutes
i.e. in one hour on an average expected customers to arrive is 60/12 =5
X being reciprocal of exponential is Poisson with parameter = 5
Probability that 10 customers arrive in one hour
=P(X=10)
=0.018133
3x+y=19
y=19-3x and y=x+3, at a solution both x and y are equal so we can say y=y:
19-3x=x+3
19-4x=3
-4x=-16
x=4, and since y=x+3
y=7 so the solution is the point:
(4,7)
