Using the quadratic formula to solve 2x2 = 4x – 7, what are the values of x? 2 plus-or-minus StartRoot 10 EndRoot i 1 plus-or-mi
AnnZ [12381]

Answer:

x = 1 +/- \frac{i\sqrt{10} }{2}

Step-by-step explanation:

The equation provided is:

2x^2 = 4x - 7\\\\2x^2 - 4x + 7 = 0

Applying the quadratic formula:

x = \frac{-b +/- \sqrt{b^2 - 4ac} }{2a}

Based on the details given:

a = 2, b = -4, c = 7

Consequently:

x = \frac{4 +/- \sqrt{(-4)^2 - 4 * 2 * 7} }{2 * 2}\\\\x = \frac{4 +/- \sqrt{(16 - 56)} }{4}\\\\x = \frac{4 +/- \sqrt{-40} }{4}\\

=> x = 1 +/- \frac{i\sqrt{10} }{2}

Suppose that a person's birthday is a uniformly random choice from the 365 days of a year (leap years are ignored), and one pers
Inessa [12570]
P ( A ∩ B ∩ C) = 1/365
P(A) = 1/365, P(B)= 1/365, P(C) = 365
For events A, B, and C to be independent, the equation P (A ∩ B ∩ C) = P (A) P(B) P(C) must hold true,
However, from the given probabilities,
1/365≠ 1/365 * 1/365 * 1/365
Therefore, it follows that events A, B, and C are not independent.
