Answer:
Percentage Calculator: 4 is what percent of 5? = 80. What is the probability of getting 5 multiple-choice questions answered correctly, if for each question the probability of answering it correctly is 1/3.
Step-by-step explanation:
If there were just one question, then the probability of guessing correctly would be 1/3. Since all the answers are independent (the answer to one question has no bearing on the answers to the others), then this is the case with each question, so the chances of guessing all answers correctly is 1/3 × 1/3 × 1/3 = 1/27.

Answer:
(1) B. f(x)->0 as x->∞, f(x)->∞ as x->-∞
(2) D. ![f(x)= 2^{-x}+5](https://tex.z-dn.net/?f=f%28x%29%3D%202%5E%7B-x%7D%2B5)
Step-by-step explanation:
. Given 0<b<1
'b' is between 0 and 1 so b should be a fraction
'b' is a fraction, so for positive value of x , the value of f(x) cannot be negative.
the graph of f(x) will goes close to 0 but it never cross x axis
So end behavior is f(x)->0 as x->∞
for negative values of x , the y value increases
So end behavior is f(x)->∞ as x->-∞
(2) f(x) = 2^x
When graph reflects across y axis, x becomes -x
so ![f(x)= 2^{-x}](https://tex.z-dn.net/?f=f%28x%29%3D%202%5E%7B-x%7D)
For translating up by 5 units we add 5 at the end
so ![f(x)= 2^{-x}+5](https://tex.z-dn.net/?f=f%28x%29%3D%202%5E%7B-x%7D%2B5)
