Scale Factor
As a word problem......
A playground is 15 cm wide. After dilation, it is 150 cm wide. What is the scale factor of the dilation?

Answer:

The slope is m=5/6 .

Answer:

C. -$4.50

Step-by-step explanation:

To find the mean of W we must first find the mean of X. So, 10/20*5+4/20*10+6/20*20=10.5

Then because mean is impacted by transformations, the mean of W=the mean of X-15=10.5-15=-$4.50

Here we need to find the expected value of the given probabilistic game.

The correct option is B: -$4.50

-------------------------------

For an event with outcomes {x₁, x₂, ...}, each one with probability {p₁, p₂, ...}, the expected value is defined as:

[tex]EV = x_1*p_1 + x_2*p_2 + ...[/tex]

Here the outcomes are:

x₁ = winning $5.

This happens if a red chip is selected, and there are 10 red chips in a bag of 20 chips, so the probability is:

p₁ = 10/20 = 1/2

x₂ = winning $10

This happens if a blue chip is selected, and there are 4 blue chips out of 20 chips, so the probability is:

p₂ = 4/20 = 1/5

x₃ = winning $20

This happens if a yellow chip is selected, and there are 6 of these in a total of 20, then the probability is:

p₃ = 6/20 = 3/10

Now we can compute the expected value:

[tex]EV = \$ 5*(1/2) + \$ 10*(1/5) + \$ 20*(3/10) = \$ 10.50[/tex]

Now if you also take in mind that you need to pay $15.00 to play, we will see that the mean of W, the amount that you won, is:

W = $10.50 - $15.00 = -$4.50

Which means that in average, you lose $4.50

Answer:

Arrange similar algebra given there ... which is 'p' here , Now ;

10p -5= - 6+2p

or, 10p -2p = -6+5

( NOTE : Moving to opposite side , + becomes - and - becomes + )

10p -2p = -6+5

8p = - 1

p = - 1 / 8

Answer:

[tex]\frac{-1}{8}[/tex]

Step-by-step explanation:

You balance the equation by getting rid of the variable on one side and then you get rid of the constant on the other then solve from there

10-5=-6+2p

10p-5-2p=-6+2p-2p

8p-5+5-6+5

8p=-1

[tex]\frac{8p}{8}=\frac{-1}{8}[/tex]

p=[tex]\frac{-1}{8}[/tex]

To solve the equation we put -1/8 in the p spot:

10x-1/8-5=-6+2x-1/8

-1.25-5=-6+-0.25

-6.25=-6.25

The equation = -6.25

Answer:

2884

Step-by-step explanation:

First plug in -10 for x, which would look like this: 734 + (-215 * (-10) ) =

Then, first you calculate everything in the parenthesis, which is (-215) * (-10)

and the equation would look like this after you multiply: 734 + 2150 =

If you noticed the number turned out positive after we multiplied, that is because - number times a - number would always be positive, just like if you divide - number by a - number your answer would be positive.

Your last step would be adding 734 with 2150. : 734 + 2150 = 2884

+ 734

2150

And the answer would be 2884

Step 1: Determine b by using the point (-6,-2), the given slope, and the slope intercept formula, y = mx + b.

[tex]y = mx + b\\\\-2 = \frac{1}{6}(-6) + b\\\\-2 = -1 + b\\\\-1 = b[/tex]

Step 2: Now that we have b, we can determine the equation of the line.

[tex]y = \frac{1}{6}x -1[/tex]

I didn't use + (-1) because b is negative. Therefore you need to change the equation from y = 1/6x + (-1) to y = 1/6x - 1.

Answer:

108π cm^3/min

Step-by-step explanation:

At a time of t min, let the height be h cm

The volume of a cylinder;

V = π r^2 h

  = 36π h

differentiating both sides with respect to t;

dV/dt = 36π dh/dt

but dh/dt = 3 cm/min

dV/dt = 36π(3) = 108π cm^3/min

Answer:

Option B. $231.13 is the correct answer.

Step-by-step explanation:

Given that

Listed price of furniture = P = $255

Discount = d = 12%

Sales tax = s = 3%

First of all, we have to find the discounted price by calculating the discount first

So,

[tex]Discount = 12\%\ of\ P\\= 0.12*255\\= 30.6[/tex]

Discounted Price:

[tex]= Listed\ Price - Discount\\= 255 - 30.6\\= 224.4[/tex]

The sales tax will be calculated on the discounted price

So,

[tex]Sales\ tax = 3\%\ of\ Discounted\ price\\= 0.03 * 224.4\\= 6.732[/tex]

Now,

[tex]Final\ price\ of\ furniture = Discounted\ price + Sales\ tax\\= 224.4 + 6.732\\=231.132[/tex]

He will actually pay $231.132 for the furniture.

Hence,

Option B. $231.13 is the correct answer.
