If you had the z-score, mean and standard deviation, how could you find the x - value? Please help, 99 points!

VladimirAG [237]

Answer:

z * sigma+u = x

Step-by-step explanation:

z = (x-u)/ sigma

z is the z score, u is the mean, sigma is the standard deviation

We need to solve for x

Multiply each side by sigma

z * sigma = (x-u)/ sigma * sigma

z * sigma = x-u

Add u to each side

z * sigma+u = x-u+u

z * sigma+u = x

Which method is the most efficient method to use to solve x^2+4x+3=0

Romashka-Z-Leto [24]

Answer:

Factoring

Step-by-step explanation:

To solve the equation $x ^ 2 + 4x + 3 = 0$ , you must apply the factoring method.

You must find two real numbers b and c such that:

$b + c = 4$

and

$b(c) = 3$

Then the expression:

$x ^ 2 + 4x + 3 = 0 = (x + b)(x + c)$

You can prove that:

$b = 3\\c = 1$

$x ^ 2 + 4x + 3 = 0 = (x + 3)(x + 1)$

$(x + 3)(x + 1) = 0$

$x +3 = 0$ or $x + 1 = 0$

$x = -3$ or $x = -1$
