Answer:

C. Action: Divide both sides by 3.

F. Property: Division property of equality.

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.

First, divide 3 from both sides of the equation:

(3x)/3 = (12)/3

x = 12/3

x = 4

C. Action: Divide both sides by 3.

F. Property: Division property of equality.

Answer:

C. Action: Divide both sides by 3.

F. Property: Division property of equality

Step-by-step explanation:

you are trying to get x by itself so if you divide by 3 you are taking the 3 from x, and what you do to one side you do to the other.

Let the graph of g be a translation 5 units up followed by a reflection about the y−axis of the graph of f(x)=6x. Write a rule f

yan [13]

Reflections and translations are instances of transformation.

The rule of function g for the given reflection and translation is $g(x) =-6x + 5$

Given

$f(x) = 6x$

The rule of translating 5 units up is:

$(x,y) \to (x,y+5)$

So, we have:

$f'(x) = f(x) +5$

$f'(x) = 6x +5$

The rule of reflecting about the y-axis is:

$(x,y) \to (-x,y)$

So, we have:

$g(x) =f(-x)$

$g(x) =6(-x) + 5$

$g(x) =-6x + 5$

Hence, the rule of function g is: $g(x) =-6x + 5$

The game of American roulette involves spinning a wheel with 38 slots: 18 red, 18 black, and 2 green. A ball is spun onto the wh

solong [7]

Answer:

a) $- \frac{1}{19}$

b) SD(x) = 0.9986

Step-by-step explanation:

Given data:

Number of slots 38

slots for red ball 18

slots for black = 18

slots for green 2

outcomes Red Black or Green

Profit 1 -1

P(X) 18/38 20/38

Expected value of wining,

$E(x) = 1. \frac{18}{38} + (-1) \frac{20}{38} = - \frac{2}{38} = - \frac{1}{19}$

B) Standard deviation of winning SD(x)

$SD(x) = \sqrt{(1- (-\frac{1}{19})^2 .\frac{18}{38} + (1- (-\frac{1}{19})^2 .\frac{20}{38}}$

$SD(x) = \sqrt{\frac{360}{361}$

SD(x) = 0.9986
