Answer:

8x² +6x+36xy² + 27y²

Step-by-step explanation:

Expand the following:

(-2 x - 9 y^2) (-4 x - 3)

(-9 y^2 - 2 x) (-4 x - 3) = (-9 y^2) (-4 x) + (-9 y^2) (-3) + (-2 x) (-4 x) + (-2 x) (-3):

-9 (-4) y^2 x - 3 (-9) y^2 - 2 (-4) x x - 3 (-2) x

-9 (-4) = 36:

36 y^2 x - 3 (-9) y^2 - 2 (-4) x x - 3 (-2) x

-3 (-9) = 27:

36 y^2 x + 27 y^2 - 2 (-4) x x - 3 (-2) x

-2 x (-4) x = -2 x^2 (-4):

36 y^2 x + 27 y^2 + -2 (-4) x^2 - 3 (-2) x

-2 (-4) = 8:

36 y^2 x + 27 y^2 + 8 x^2 - 3 (-2) x

-3 (-2) = 6:

Answer: 36 y^2 x + 27 y^2 + 8 x^2 + 6 x

10% of a group is left handed. If a random sample of 12 switches is selected, what is the probability of exactly two of the swit
Paraphin [41]
Assuming that 10% is the probability of a switch being defective (since left-handedness has nothing to do with the problem):
For a binomial distribution, probability(r out of n) = (nCr) (p)^r (q)^(1-r)
p = 10% = 0.1, q = 1 - p = 0.9
r = 2 switches, n = total of 12 switches
probability = (12C2) (0.1)^2 (0.9)^(12-2)
probability = 66(0.1)^2 (0.9)^10
probability = 0.23
