Answer:
The probability that no calls will occur during the next ten minutes is 0.0907.
Step-by-step explanation:
Poisson distribution:
Poisson distribution is a statistical distribution that helps to find out the number of events is likely occur in a specific time period.
Given that,
Calls occur at an average rate of 1.2 every 5 minutes.
The average rate of call is per minute.
Here,
, t=10 and x=0
=0.0907
The probability that no calls will occur during the next ten minutes is 0.0907.
Answer:
The new coordinates are (-6,-3) inside the third quadrant!!!!
So the formula for slope is (y2 - y1)/(x2-x1), so here that would be
(-5-(-20))/(-18-(-18)) which would simplify to
(-4 +20)/(-18+18) = 16/0 and you cannot divide by 0 so the slope would be undefined
