Answer:
Domain and range are the set of all real numbers.
Step-by-step explanation:
Given that Ann thought of a number N, multiplied it by 5 and added 7. Then she told the result R to Jim
Here no restriction is mentioned for the number N.
It can be any number but real.
Hence we can say that domain is the set of all real numbers
For range let us calculate y for any x
If Ann thought of x as the number then
she would multiply by 5 to get 5x and add 7 to get 5x+7
Hence y =5x+7
Since y has no exception here range can also be the set of all real numbers
Answer = V (2,1)
Because:
The equation of the circle is
(x+1)² + (y+3)² = 25
(2+1)² + (1+3)² = 25
3² + 4² = 25
9 + 16 = 25
25 = 25
It would be 3.25555555555555........
hope this helps!!
The first card has to be 25 or less, which is 50% and the next card has to be a single card, which is 1/49. This will give you the answer of 1/98
