The factors of 2x^2 + xy - 3y^2 are A (2x - 3y)(x + y)

B (2x + 3y)(x - y)

C (2x - y)(x + 3y)

D (2x + y)(x - 3y)

B. (2x + 3y)(x - y)

Step-by-step explanation:

              Write x y as a difference

   Factor out x from the equation

  Factor out 2x+3y from the expression

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
