Answer: B

<u>Step-by-step explanation:</u>

x³ - 3x² + 16x - 48 = 0

→ x²(x - 3) + 16(x - 3) = 0

→ (x² + 16) (x - 3) = 0

→ (x² - (-16)) (x - 3) = 0

→ (x - 4i)(x + 4i)(x - 3) = 0

→ x - 4i = 0 x + 4i = 0 x - 3 = 0

→ x = 4i x = -4i x = 3

If you flipped the coin 100 times, how many heads would you expect to get? Explain your answer.

Irina18 [472]

Answer:

You would expect to get 50 heads

Step-by-step explanation:

Each time you flip a coin you will either get heads or tails. This means that you have a 1/2 probability of getting heads. If you use this then you need to multiply 1/2 and 100 to get the expected amount of heads. Multiplying by a half is just dividing by 2. Therefore, the answer is 100/2 = 50. The answer is 50 heads
