Answer:
2.35 calls
Step-by-step explanation:
The presented scenario can be modeled by a Poisson distribution with an average number of calls (μ) of 5.5 during the noon hour on Mondays.
Therefore, the standard deviation for the number of calls received, X, is given by:
The standard deviation of X is 2.35 calls.
Answer: +
+
+ 2
Step-by-step explanation:
f(x) = - 4x + 2
g(x) = + 2
To find fg(x) , we have
fg(x) = f( + 2 )
The next thing is that , we will substitute + 2 for the value of x in f(x) , so we have:
- 4(
+ 2) + 2
which will give
+
+
+ 2
Therefore :
fg(x) = +
