Answer:

-2

Step-by-step explanation:

We know that the object is at 12 on a horizontal line.

The horizontal line of a graph is the x axis, so lets think of 12 as 12x

On a graph, left is negative, and right is postive.

In this case we need to move 14x to the right, or -14x.

We start at 12x, so its going to be:

12x-14x=-2x

So -2 is the postition of the object on the x axis.

This is answer B.

Hope this helps!

An attendant at a car wash is paid according to the number of cars that pass through. Suppose that following payments are made w

QveST [7]

Answer:

$E(X) = 7*0.18 +9*0.08 +11*0.09 +15*0.08 +17*0.41 =13.22$

And we can find the second moment with this formula:

$E(X^2) = \sum_{i=1}^n X^2_i P(X_i)$

And replacing we got:

$E(X^2) = 7^2*0.18 +9^2*0.08 +11^2*0.09 +15^2*0.08 +17^2*0.41 =189.72$

And we can find the variance like this:

$Var(X) = E(X^2) -[E(X)]^2= 189.72- (13.22)^2 =14.9516$

And the deviation would be:

$Sd(X)= \sqrt{14.9516}= 3.867$

Step-by-step explanation:

For this case we have the following dataset given:

Payment $7 $9 $11 $13 $15 $17

Probability 0.18 0.08 0.09 0.16 0.08 0.41

For this case we can calculate the mean with this formula:

$E(X) = \sum_{i=1}^n X_i P(X_i)$

And replacing we got:

$E(X) = 7*0.18 +9*0.08 +11*0.09 +15*0.08 +17*0.41 =13.22$

And we can find the second moment with this formula:

$E(X^2) = \sum_{i=1}^n X^2_i P(X_i)$

And replacing we got:

$E(X^2) = 7^2*0.18 +9^2*0.08 +11^2*0.09 +15^2*0.08 +17^2*0.41 =189.72$

And we can find the variance like this:

$Var(X) = E(X^2) -[E(X)]^2= 189.72- (13.22)^2 =14.9516$

And the deviation would be:

$Sd(X)= \sqrt{14.9516}= 3.867$

What is the quotient? URGENT!!

jeyben [28]

Answer:

The answer is A.

Step-by-step explanation:

You have to multiply by converting the second fraction into upside down :

$\frac{4x + 1}{6x} \div \frac{x}{3x - 1}$

$= \frac{4x + 1}{6x} \times \frac{3x - 1}{x}$

$= \frac{(4x + 1)(3x - 1)}{x(6x)}$

$= \frac{12 {x}^{2} - 4x + 3x - 1}{6 {x}^{2} }$

$= \frac{12 {x}^{2} - x - 1 }{6 {x}^{2} }$
