What is the variation constant for an inverse squared relationship where we know x = –4 and y = 3?

1 answer:

6 0

Let the constant be k.

For an inverse squared proportion the formula is y = k/x^2

Insert values of y and x into the formula.
3 = k/(-4)^2
3(-4)^2 = k
k = 3(16)
k = 48

Hope this helps. :)

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.

Answer:

$9450

Step-by-step explanation:

We will use compound interest formula:

$F=P(1+r)^t$

Where

F is future amount [what we want to figure out]

P is present amount [9000]

r is rate of interest [since we want for 6 months, the annual interest divided by 2 is r. So r = 10/2 = 5% or 0.05]

t is the time [ the time period is for 6 months so t = 1 since we already converted the interest rate to 6 month chunk]

Putting in formula, we get:

$F=P(1+r)^t\\F=9000(1+0.05)^1\\F=9000(1.05)\\F=9450$

Solve for c; a/b+c=d/c

Eduardwww [97]

To solve for c, you need to get c onto one side of the equation, or make it c=__. So what I would do first is subtract a/b from both sides

a/b + c = d/c

-a/b

a/b - a/b + c = d/c - a/b

c = d/c-a/b
