Answer: The probability that his friend doesn't make a shot until his 5 th attempt is 0.00128.
Step-by-step explanation:
Since we have given that
Probability of making his shot = 80%
Probability of missing his shot = 20%
We need to find the probability that his friend doesn't make a shot until his 5th attempt.
So, our required probability would be

Hence, the probability that his friend doesn't make a shot until his 5 th attempt is 0.00128.
No greater means equal or less. Because the problems asks about the highest score(maximum value), we are going to solve following equation:
(72+78+73+x)/ 4 = 74
(72+78+73+x)=74*4
223+x=296
x=296-223= 73
Answer is 73.

Answer:
f(x) = 4·49^x
Step-by-step explanation:
We assume your funtion is supposed to be
... f(x) = 4·7^(2x)
Then the exponent can be rearranged so you have ...
... f(x) = 4·(7^2)^x = 4·49^x
