X = –6 3x − 2y = –6 solve using substetution <br> NEED FAST
kondaur [170]

Answer:

(x = -6), (y = -6)

(-6,-6)

Step-by-step explanation:

X=-6

3x - 2y = -6

3(-6) - 2y = -6

-18 - 2y = -6

What you do to one side, you do to the other. And when you take it over to the other side, you'll have to turn -18 into a positive 18.

-2y = 18 - 6

-2y = 12

Divide both sides by -2

y = -6

Suppose the discrete random variable X has the probability distribution below:
Talja [164]

(a) P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.11 + 0.52 + 0.19 = 0.82

(b) P(X ≥ 1) = P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) = 0.52 + 0.19 + 0.12 + 0.06 = 0.89

(c) µ = 0×0.11 + 1×0.52 + 2×0.19 + 3×0.12 + 4×0.06 = 1.5

(d) σ² = (0²×0.11 + 1²×0.52 + 2²×0.19 + 3²×0.12 + 4²×0.06) - µ² = 1.07

σ = √(σ²) ≈ 1.03
