Answer:

  • D. A = x² + 44x = 808

Step-by-step explanation:

Check if the relationship is linear. Verify the difference between areas.

We can see the difference is not common.

It means we can exclude options B and C.

The remaining options are quadratic (A and D).

<u>Try the last column with option A:</u>

  • 4813 = 45² + 1908
  • 4813 = 3933
  • False

<u>Verify the last option:</u>

  • 4813 = 45² + 44*45 + 808
  • 4813 = 4813
  • Correct

We can check and confirm the other columns are correct as well.

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.
