m_a_m_a [10]

<u>the</u><u> </u><u>median</u><u> </u><u>is</u><u> </u><u>19.5</u>

Step-by-step explanation:

To find the median you list all numbers in number order, which you already have and find the center number.

13, 14, 17, 18, 21, 23, 26, 28

/ / / 19.5 / / /

If there are two numbers left you can add then together and divide by 2 to find the median.

Suppose the market demand for a good is described by the equation P = 80 - 2Q. If a change in market supply results in price dec
liraira [26]
Calculate Q (consumer surplus) when P = 60

60=80-2Q ⇒ Subtract 60 from both sides
60-60=80-2Q-60
0=20-2Q ⇒ Add 2Q to both sides
0+2Q = 20-2Q+2Q
2Q=20 ⇒ Divide both sides by 2
\frac{2Q}{2} = \frac{20}{2}
Q=10

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

Calculate Q when P = 50

50=80-2Q
50-50=80-2Q-50
0=30-2Q{/tex] [tex]0+2Q=30-2Q+2Q
2Q=30
Q=15

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

As the value of P decreasing, the value of Q increases from 10 to 15

Airplane is flying at 9000 feet.It begins descending at a rate of 500 feet per minutes write an equation
Hunter-Best [27]

Answer:

9000 - 500m

Step-by-step explanation:

Your original number is 9000. It starts to decrease at a rate of 500 feet per minute. So we know that you will subtract 500 from 9000 but we don't know how many times. Because of this, we will put a variable to represent the minutes that we are descending.

In conclusion: 9000 - 500m
