General Formulas and Concepts:

Pre-Alg

Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define

g(x) = 2x² - 12

g(-3) is x = -3

Step 2: Solve

Substitute: g(-3) = 2(-3)² - 12
Evaluate: g(-3) = -2(9) - 12
Multiply: g(-3) = -18 - 12
Subtract: g(-3) = -30

The sales price of a single family house in Charlotte is normally distributed with mean $210,000 and standard deviation $35,000.

Lady_Fox [76]

Answer:

E(X ¯)=210,000.

Step-by-step explanation:

A sampling distribution for samples of size n=49 from a population with means μ=210,000 and standard deviation σ=35,000, has the following means anda standard deviation:

$\mu_s=\mu=210,000\\\\\sigma_s=\sigma/\sqrt{n}=35,000/\sqrt{49}=35,000/7=5,000$

If X ¯ is the mean sales price of the sample, it will have a mean value of E(X ¯)=210,000.

i think you mean discriminant in part A 
Δ=b^2-4ac=256-4*2*3=256-24=232
it is positive so it has two answers.
Part B
you can find Δ
Δ=b^2-4ac=9-4*9*(-2)=81
x1=-3+9/18=6/18=1/3
x2=-3-9/18=-12/18=-2/3
