If y varies directly with x, that means they change at proportion rates. We can define their relationship using a constant k.

y = kx

Plug in what we know to find k.

-3 = 5k

k = -3/5

So:

y = -1 * (-3/5)

y = 3/5

The U.S. Department of Housing and Urban Development (HUD) uses the median to report the average price of a home in the United

MatroZZZ [7]

Answer:

Step-by-step explanation:

given that the U.S. Department of Housing and Urban Development (HUD) uses the median to report the average price of a home in the United States.

We know that mean, median and mode are measures of central tendency.

Mean is the average of all the prices while median is the middle entry when arranged in ascending order.

Mean has the disadvantage of showing undue figure if extreme entries are there. i.e. outlier affect mean.

Suppose a price goes extremely high, then mean will fluctuate more than median.

So median using gives a reliable estimate since median gives the middle price and equally spread to other sides.

Where would you place root 8 on the Venn diagram? A) integers B) natural numbers C) rational numbers D) irrational numbers

tangare [24]

Answer:

Option (D)

Step-by-step explanation:

All rational and irrational numbers are real numbers.

{-2, -1, -1.8, 0, 1, 2.......}

Numbers written in the form of $\frac{p}{q}$ are rational numbers. They are the part of irrational numbers.

{-2.5, -2, -1, 0, 1, 2.....}

Whole numbers with negative or positive notation are integers.

{-3, -2, -1, 0, 1, 2, 3, 4......}

Positive integers are the whole numbers (including zero).

{0, 1, 2, 3, 4, .......}

All whole numbers excluding zero are the natural numbers.

{1, 2, 3, 4,........}

Irrational numbers are the part of real numbers written in the form of $\frac{p}{q}$ .

{ $\sqrt{2},\sqrt{5},\pi, \sqrt{10}$ }

Therefore, $\sqrt{8}$ comes under Irrational numbers.

Option (D) is the answer.

The volume of the triangular prism is 54 cubic units.What is the value of x?

nadezda [96]

Answer:

x=3

Step-by-step explanation:

the volume of the prism with triangular base is 54 unit³

The base is a triangle with, base i.e 4 units and height i.e x units

Also, height of the prism = 3x

So, volume of the prism is,

And

$Area_{Triangle}=\dfrac{1}{2}\times base\times Height_{Triangle}=\dfrac{1}{2}\times 4\times x=2x\ unit^2$

Then,

$V_{Prism}=2x\times 3x=6x^2$

As the volume is given as 54 unit³, hence

6x²=54

x²=9

x=3
