Answer:

$234

Step-by-step explanation:

Let x be the money made in sales. Let y be the commission.

First, convert 13% to a decimal.

13% = 0.13

Make your equation:

0.13x = y

Plug in the value of sales for x.

0.13(1800) = y

y = $234

Which expressions represent the product of exactly two factors?

egoroff_w [7]

Answer:

B, C,

Step-by-step explanation:

A - This is addition. Finding a product refers to multiplication, so this is not correct.

B - This is multiplication of 5x × 5y, exactly two factors, so this is correct.

C - This is multiplication of (x-y) × (x+y). Each equation inside the parenthesis equals one factor, so this is multiplication of exactly two factors. This answer is also correct.

D - This is multiplication of three factors, x × y × z, and is not correct.

What is the equation for the translation of x2 + y2 = 16 seven units to the right and five units up?

mafiozo [28]

Answer:

$(x-7)^2+(y-5)^2=16$ .

Step-by-step explanation:

The given circle has equation $x^2+y^2=16$ .

This is the equation that has its center at the origin with radius 4 units.

When this circle is translated seven units to the right and five units up, then the center of the circle will now be at (7,5).

The equation of a circle with center (h,k) and radius r units is $(x-h)^2+(y-k)^2=r^2$ .

This implies that, the translated circle will now have equation.

$(x-7)^2+(y-5)^2=4^2$ .

$(x-7)^2+(y-5)^2=16$ .

Answer:

Option A ( -3/2 , $\frac{-3\sqrt{3} }{2}$ )

Step-by-step explanation:

According to Question, The Spinner Rotate 600* Thus after Completing 360* it Comes Exactly Where It Started . Now again rotate It 180* .

Now We Are on ( -X axis ) & Completed 360*+180*=540* Rotation

Now After Rotate It 60* More we come in Third Quadrant & Here In Third Quadrant Only Tangent & Cotangent Is Positive .(Sine & Cosine is Negative)

(For Diagram, Please Find in attachment)

Now In Triangle OAB

Cos60* = OA / OB

1/2 = -X / 3 Thus X= -3/2

Sin60* = AB / OB

$\sqrt{3}$ /2 = -Y / 3 Thus Y = - $\sqrt{3}$ * 3 /2

You are interested in estimating the the mean age of the citizens living in your community. In order to do this, you plan on con

AlladinOne [14]

Using the z-distribution, a sample size of 180 is needed for the estimate.

<h3>What is a z-distribution confidence interval?</h3>

The confidence interval is:

$\overline{x} \pm z\frac{\sigma}{\sqrt{n}}$

The margin of error is given by:

$M = z\frac{\sigma}{\sqrt{n}}$

In which:

$\overline{x}$ is the sample mean.

z is the critical value.

n is the sample size.

$\sigma$ is the standard deviation for the population.

In this problem, we have a 98% confidence level, hence $\alpha = 0.98$ , z is the value of Z that has a p-value of $\frac{1+0.98}{2} = 0.99$ , so the critical value is z = 2.327.
