Answer:
Rate parameter of 
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:
In which
is the decay parameter.
One appearance per two minutes.
This means that 
Measured in minutes, the time T until the next encounter is Exponential with what rate parameter?

So
Rate parameter of 
Answer:
If she is growing 12 inches a year, then it would take her 6 months to grow 6 inches. Unless you didn't write the question correctly, none of those are the answer..
Answer:
go to the doctor
Step-by-step explanation:
The correct answer is shown in attached figure
To find the correct graph, we should study the continuity of the function
Check the continuity at x = -2
from the left ⇒⇒ f(-2) = 1/2 * -2 + 3 = 2
from the right ⇒⇒ f(-2) = 2
∴ The function is continuous at x = -2
Check the continuity at x = 3
from the left ⇒⇒ f(3) = 2
from the right ⇒⇒ f(3) = 2*3 - 3 = 3
∴ The function is jump discontinuous at x = 3
From the previous results the correct graph is the last as shown in attached graph.
