Answer:
C. A horizontal stretch to produce a period of and a vertical compression.
Step-by-step explanation:
We are given the parent function as
It is given that, transformations are applied to the parent function in order to obtain the function i.e.
That is, we see that,
The parent function is stretched horizontally by the factor of
which gives the function
.
Further, the function is compressed vertically by the factor of which gives the function
.
Now, we know,
If a function f(x) has period P, then the function cf(bx) will have period .
Since, the period of is
, so the period of
is
=
Hence, we get option C is correct.
Answer: 0.7619
Step-by-step explanation:
Given : Mean :
Standard deviation :
Sample size :
We assume that the variable is normally distributed.
The value of z-score is given by :-
a) For x= 46.9 years
The p-value :
Hence, the probability that the average age of those doctors is less than 46.9 years =0.7619
