Answer:
C
Step-by-step explanation:
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 .
(x-3)^2+(y-2)^2=25
plug in those values for x,y to see if they satisfy the equation (=25)
Answer:
28451= 20000+8000+400+50+1
value of 8 =8000
