The inverse fraction of 15x+14 is f^-1 (x)= x/15-14/15
150 times
out of the first 5 cards, there is a 3/5 chance of drawing a yellow.
if you replace the card and draw again, you still have a 3/5 chance of drawing a yellow card.
keep doing this process for 250 draws, each draw will always have 3/5 chance of drawing a yellow card.
so 3/5 +3/5 +3/5 +... (250 times) = 250 x 3/5 = 150
-2 * 2n -2 equals -4n + 4 > 18n -3n
To add or subtract with powers, both the variables and the exponents of the variables must be the same. You perform the required operations on the coefficients, leaving the variable and exponent as they are.
Answer: 20
explanation: simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers
