The museum is at (2, -1 3/4). To find the reflection, the y-value of the point becomes the opposite sign , but the x-coordinate remains the same. In other words, the hotel is the same distance away from the x-axis as the museum, just in the opposite direction. This means that the hotel is at (2, 1 3/4)
Step-by-step explanation:
y=2×2-4x-7
o=4-4x-7
4x=4-7
4x=-3
x =<u> </u><u>-</u><u>3</u>
<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>4

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.
The expectation value is simply obtained by multiplying the probability of each outcome by each possible value. These are then summed for each outcome to obtain the expectation value. In the board game, if there is a 60% chance that you will move 4 spaces forward (+4) and a 40% chance that you will move back 2 spaces then expected value for number of spaces is (0.6 x 4) + (0.4 x -2) = 2.4 - 0.8 = 1.6 spaces.
Multiply straight across:
-6 x -8 = 48
5 x 9 = 45
Simplify:
48/45 = 16/15
16/15, or 1 1/15 is your answer
