If you were to flip a coin 500 times, how many times would you theoretically expect the coin to land on heads?

Answer and Step-by-step explanation:

Theoretically, we should expect the coin to flip 250, or very close to 250 times, and land on heads.

This is because the probability of getting heads is , or 50%.

There is a 50% chance of landing heads or tails, so that means it would land 250 times on heads out of 500 flips of the coin.

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
