1. 6x-15
2. 18x-55
3. 7.2x+2.3y-2
The median is the number in the middle...so write your frequencies out, in least to greatest and find the one that falls in the middle.
Let's calculate the total cost per year:
6168 + 3280 + 2190 + 1200 = 12,838.
Four years will cost 12838 x 4 = 51,352
Your family will help you out with 17,600, so you will need to pay:
51352 - 17600 = 33,752
Your answer would be 8, i recommend a website called desmos for graphing online
Answer:
![\[\frac{3}{4}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B3%7D%7B4%7D%5C%5D)
miles
Step-by-step explanation:
The relay team consists of 4 people.
Total distance covered by 4 people = 3 miles
Each person runs the same distance.
This means that each person will run a distance equal to:
![\[\frac{distance}{persons}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7Bdistance%7D%7Bpersons%7D%5C%5D)
![\[=\frac{3}{4}\]](https://tex.z-dn.net/?f=%5C%5B%3D%5Cfrac%7B3%7D%7B4%7D%5C%5D)
So each person in the relay team of 4 will run a distance of miles to cover the entire length of 3 miles.
