PLEASE HELP<br>Find the solution of this system of equations <br> -5x=-21+6y <br> -5x+y=-84

NeTakaya

-5x - 6y = -21
5x - y =. 84

-7y = 63

y= -9

-5x = -21 - 54

-5x = -75

x = 15

Suppose that X1 and X2 are independent random variables each with a mean μ and a variance σ^2. Compute the mean and variance of

Deffense [45]

Mean:

E[Y] = E[3X₁ + X₂]

E[Y] = 3 E[X₁] + E[X₂]

E[Y] = 3µ + µ

E[Y] = 4µ

Variance:

Var[Y] = Var[3X₁ + X₂]

Var[Y] = 3² Var[X₁] + 2 Covar[X₁, X₂] + 1² Var[X₂]

(the covariance is 0 since X₁ and X₂ are independent)

Var[Y] = 9 Var[X₁] + Var[X₂]

Var[Y] = 9σ² + σ²

Var[Y] = 10σ²

Answer:

x ≤ $\frac{19}{4}$

Step-by-step explanation:

Given

$\frac{x-1}{3}$ - 2 ≤ $\frac{5-2x}{6}$

Multiply through by 6 to clear the fractions

2(x - 1) - 12 ≤ 5 - 2x ← distribute and simplify left side

2x - 2 - 12 ≤ 5 - 2x

2x - 14 ≤ 5 - 2x ( add 2x to both sides )

4x - 14 ≤ 5 ( add 14 to both sides )

4x ≤ 19 ( divide both sides by 4 )

x ≤ $\frac{19}{4}$
