Plan A:
15+(0.25x)
15+(0.25×80)
15+(20)
35
Plan B:
20+(0.05x)
20+(0.05×300)
20+(15)
35
I am sure there are other numbers that you can use but I just choose the number 35! Good luck!
we solve the second system: (it is more easy).
8x+9y=48
-8.5y=-51 ⇒y=-51/-8.5=6
8x+9(6)=48
8x+54=48
8x+54-54=48-54
8x=-6
x=-6/8=-3/4
Then; in te second system the solution is : x=-3/4; y =6
Now, we replace "x" by "-3/4" and "y" by "6", in the first systmen.
8x+9y=48
8(-3/4)+9(6)=-6+54=48. verified
12x+5y=21
12(-3/4)+5(6)=-9+30=21 verified
Therefore,
These two wystems are similar.
N+3 most likely it is increasing by 3 every time so n+3
You divide 240 miles by 6 cm so you can figure out how many miles are in each centimeter. So 240/6=40 miles. The scale is for every one centimeter, that is 40 miles.
Answer:
Step-by-step explanation:
1. List out all data from least to greatest
2. Find the median (the middle number)
3. Find the median of the lower part of data (the numbers lesser in value compared to the median; do not include the median while finding this)
4. Do the same with the numbers above the median.
5. Take the medians of the lower numbers and higher and find the difference,
6. Thats your interquartile range
