Answer:
D. Randomly draw and replace a card 100 times. Then, observe how close to 20 times a club is drawn.
Step-by-step explanation:
We are given that,
Martha predicts that 'whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time'.
Now, according to the options, we see that,
If she randomly draw and replace a card 100 times and then observe how close to 20 times a club is drawn.
Her prediction is most likely to be true.
As, 20 out of 100 times is th of the total time.
Hence, option D is correct.
ANSWER
EXPLANATION
The given function is
To find f(a+2) we substitute x=a+2.
That is wherever we see 'x' we replace it with 'a+2'
We simplify further to obtain:
This is defined for
