Given :
Levi answered 8 questions correctly out of 10 turns in the game.
Then answered the next three questions correctly.
He reasoned that because he added 3 to both the total questions and his correct responses, that the ratio of correct answers to total questions remained the same.
To Find :
Is he correct or not .
Solution :
Initially total number of questions are 10 and he answered 8 of them correctly .
So , ratio of correct ans to total ans is :
Now , he added more three questions and able to solve all of them .
So , new ratio is :
Therefore , the ratio of correctly answered and and total questions will not remain same .
Hence , this is the required solution .
So , total number of questions now are 13 and correctly answered are 11 .
Answer:
a. 22,957,480
Step-by-step explanation:
The order in which the numbers are picked is not important, which means that we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
In this problem:
6 numbers from a set of 53. So
The inverse of f(x)=3x+1 is f(x)−1=13x−13 .
