Answer:

170

Step-by-step explanation:1/4 is just like dividing 4 so 680 divided by 4 equals 170

Scale factor is defined as
s=size of image / size of preimage.

Here BO is preimage.
B'O'=BO' is image, since the position of B is invariant, so B=B'.

So scale factor = B'O'/BO = 9/27 = 1/3.

Fiesta28 [93]
<h3>The exact probability that the blue ball is drawn first and the red ball is drawn second is \frac{1}{132}</h3>

<em><u>Solution:</u></em>

<em><u>The probability of an event is given as:</u></em>

Probability = \frac{ \text{ number of favorable outcomes }}{ \text{ total number of possible outcomes }}

Given that,

There are 12 balls in a bag

One is blue and one is red

Favorable outcome = blue ball is drawn first

Favorable outcome = 1

Therefore,

Probability = \frac{1}{12}

Now, without replacement, red ball is drawn second

Therefore,

Total possible outcomes = 12 - 1 = 11

Probability = \frac{1}{11}

<em><u>What is the exact probability that the blue ball is drawn first and the red ball is drawn second?</u></em>

Total\ probability = \frac{1}{12} \times \frac{1}{11} = \frac{1}{132}

Thus the exact probability that the blue ball is drawn first and the red ball is drawn second is \frac{1}{132}

we conclude that the dimensions and area of the scaled figure are:

  • l₂ =  48 in
  • w₂= 32in
  • A₂ =  1,536 in^2

How to find the dimensions of the large rectangle?

First, we know that the large rectangle is the smaller rectangle rescaled, with a scale factor k = 4.

This means that each dimension of the smaller rectangle must be multiplied by 4 to get the correspondent dimension on the larger rectangle.

The dimensions of the smaller rectangle are:

l₁ = 12in

w₁ = 8in

Then the correspondent dimensions of the large rectangle are:

l₂ = 4*12in = 48 in

w₂= 4*8in = 32in

Now, the area of the large rectangle is given by the product between the two dimensions, we will get:

A₂ = 48in*32in = 1,536 in^2

Then, we conclude that the dimensions and area of the scaled figure are:

  • l₂ =  48 in
  • w₂= 32in
  • A₂ =  1,536 in^2

Answer:

Okay so I’m gonna do a few and list a few examples

In slope intercept form its

y=mx+b

Y= Random Y coordinate (Not that important for now while writing)

m= Slope

X= random x coordinate (not that important for now while writing)

b= Y intercept

SO basically plug it in like that so for the first one

the slope is 1/3  and y-intercept is -1

so

y=1/3x-1

And thats how you do it

leave the y and x

Graphing

So for graphing or fining the equation, first identify the y-intercept

The y-intercept is on the y axis (obviously), and its the number where the line first hits, so for the first one, the y intercept is 3 becuase thats where the first line meets on the Y axis. When identified start doing rise over run, lik just go up and right, if there is no space, dot he opposite, go down and go left or right (depends if the line is rising or falling, you can tell if rising (positive) if the line goes from down to up form left to right , if falling (negative) vice versa, up to down from left to right). And just write the equation after identifying the slope And y-intercept, the x and y don’t matter.

4) y= -1/3x+3 (watch your signs, if falling the slope is automatically negative)

5) y=1/2x+1

6) y=4x-5 (negative y-intercept due to the part where the y meets up with the line, its in the negative side)

(remember to write these equations on the top side of the line
