Answer:
Step-by-step explanation:
![~~~2x^3y-2y\\\\=2y(x^3-1)\\\\=2y(x-1)(x^2+x+1)~~~~~~~~~~;[a^3-b^3 = (a-b)(a^2 +ab+b^2)]](https://tex.z-dn.net/?f=~~~2x%5E3y-2y%5C%5C%5C%5C%3D2y%28x%5E3-1%29%5C%5C%5C%5C%3D2y%28x-1%29%28x%5E2%2Bx%2B1%29~~~~~~~~~~%3B%5Ba%5E3-b%5E3%20%3D%20%28a-b%29%28a%5E2%20%2Bab%2Bb%5E2%29%5D)
P(heads or tails) = 1 This is because when flipping a coin, there are only two possible answers, either heads ir tails so the probability of getting either one is 100%. However, if you're asking for P(heads) = 1/2, and P(tails)= 1/2.
It would be 3.01 because 40.00-40.00 is 0 then take away the other numbers 3.68- 0.67 is 3.01
Clara= 30+45 (75)
Adam = 2x75 (150)
745+5+150=270min
