Step-by-step explanation:
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:
A
Step-by-step explanation:
If two lines are perpendicular, the slopes are the negative reciprocals of each other. If one slope is 5, then the other is -1/5.
Answer:
x = -7
Step-by-step explanation:
The whole line is 12
the whole line is also x + 14 and x + 12
so make them equal:
x+14 + x +12 = 12
2x + 26 = 12 now subtract 26 from both sides
2x = - 14 now divide both sides by 2
x = -7
