Answer: 85.5
Step-by-step explanation:
There are 22 data points in the data set.
We can find the median by looking at the 11th and 12th scores, and averaging them.
The 11th score is 85
The 12th score is 86
The average of the two is 85.5
Hence the answer is 85.5
Answer:
Well around 5-8 miles were jogged daily.
Step-by-step explanation:
Thats all i know
Multiply the first equation by 4 (so that both equations will have 8x terms) and then subtract:
8x-20y = -24
8x +3y = 68
------------
0 -23y = -92
Now divide both sides by -23:
y = 4
Find x by plugging y=4 into either equation:
8x +3(4) = 68
8x = 68 - 12
8x = 56
x = 7
So the answer is ordered pair is (7,4)
