Data Set A: 3, 5, 7, 10, 10, 4, 7, 5, 8, 10, 6. Find the median Hint: Arrange them in ascending order first!
DENIUS [597]
The median of these numbers is: 7
3,4,5,5,6,7,7,8,10,10,10
Track teaches you to be able to achieve your best speed in one of the quickest ways possible. The activity supports the skill because the more mitochondria you have, the more energy you are able to produce during exercise, which will enable you to run with greater speeds. If track is done regularly, it increases the size of the mitochondria. Giving you more energy, which will generate more speed. ( Hope this helps! (: )
Answer:
Step-by-step explanation:
Hello,
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
We have two formulas:
Adult tickets plus Student tickets = 550 tickets or A + S = 550
and
Adult tickets times $20 plus Student ticket times $10 = $7500 or
(A * 20) + (S * 10) = 7500
First let's get rid of one of the variables by re-balancing the simplest formula
A+S = 550
A+S-A = 550-A
S = 550-A
Now we can restate the second formula replacing "S" with it's equivalent "550-A"
(A * 20) + (S * 10) = 7500
(A * 20) + ((550-A) *10) = 7500
Then do the multiplication
20A + 5500 - 10A = 7500
and simplifiy
20A + 5500 - 5500 - 10A = 7500 - 5500
20A - 10A = 2000
10A = 2000
A = 200
S = 550 - 200 = 350
Now we should test the answers to be sure our work
is correct:
200 Adult tickets times $20 = $4000
350 Student tickets times $10 = $3500
$4000 + $3500 = 7500
