In 1000 tosses of a fair quarter, nickel, and dime, what is the most likely number of times the quarter and dime will come up heads and the nickel will come up tails

This is about circle theorems. someone asap : (

How is the equation of this circle written in standard form? x2 + y2 - 6x + 14y = 142 a) (x - 3)2 + (y + 7)2 = 200 b) (x+ 3)2 + (y - 7)2 = 200 (x - 6)2 + (y + 14)2 = 142 d) (x+6)2 + (y- 14)2 = 142

Using only odd number for numerators write two different subtraction problems that have a difference of 3/4
