Answer:

Dilation is the type of change that changes the size of the image and has a scale factor. Which measures how large or small a picture is and is also called a scalar factor. You can determine the scale factor by starting with ΔABC, and then draw the dilation picture of the triangle with the middle at the origin and a scale factor of two. On the other hand, notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). Dilation also has a scale factor 2, multiply by 2.

The table shows how many males and females attended two different movies. How would you find the joint relative frequency of bei

kirza4 [7]

Answer:

B. Divide 124 by 229.

Step-by-step explanation:

Given the table

$\begin{array}{cccc}&\text{Action}&\text{Drama}&\text{Total}\\ \\\text{Male}&105&124&229\\ \\\text{Female}&99&151&250\\ \\\text{Total}&204&275&479\end{array}$

The <u>joint relative frequency</u> is the ratio of the frequency in a particular category and the total number of data values.

The total number of males $=229$

The number of males that like drama $=124$

So, to find the joint relative frequency of being male and attending a drama movie, you should divide 124 by 229.

Alan is comparing the cost of a fresh lobster dinner at two different restaurants. The first

Pepsi [2]

Good evening ,

Answer:

The weight : 29 pound

Alan would pay for his dinner : $130

Step-by-step explanation:

Let x represent the weight of the lobster

the cost of the dinner at restaurant 1 is 4x + 14

the cost of the dinner at restaurant 2 is 3x + 43

Now ,we have to solve the equation : 4x + 14 = 3x + 43

4x + 14 = 3x + 43

⇔ x = 43 - 14

⇔ x = 29

In this case Alan would pay the same amount for his dinner at any restaurant:

the price = 4×(29)+14 = 130

= 3×(29)+43 = 130.
