Zielflug [23.3K]

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 \frac{1}{5} th of the total time.

Hence, option D is correct.

If f (x) equals 3 + x / x - 3 what is f (a + 2)?​
xenn [34]

ANSWER

f(a + 2) =  \frac{a + 5}{a  - 1}

EXPLANATION

The given function is

f(x) =  \frac{3 + x}{x - 3}

To find f(a+2) we substitute x=a+2.

That is wherever we see 'x' we replace it with 'a+2'

f(a + 2) =  \frac{3 + a + 2}{a + 2 - 3}

We simplify further to obtain:

f(a + 2) =  \frac{a + 5}{a  - 1}

This is defined for

a \ne1
