The one you chose is correct
commute means to move around, so it's be
a + b = b + a
Answer:
2.5
Step-by-step explanation:\
We can solve it like this
4 + x = 6.5
6.5 - 4 = x
6.5 - 4 = 2.5
SO
4 + 2.5 = 6.5
13, 17, 15, 18, 21, 13, 20;(the add 3.7 has no place in this data set .Ignore it)
1) arrange the data from smaller to greater: 13 13 15 17 18 20 21
2) mean: Add up all data & divide by the number of data
that is 7==> (117/)/7 so the mean = 16.71
3) Median is the central value of the data point that is in the middle of the sequence, so the median is 18
4) Mode the number that is most repeated & it's 13 (repeated twice)
5) The range is the difference between the largest & the smallest
Range = 21-13 ==> Range = 8
There is a problem in answers you have written: Either you mistyped or omitted something or the answer are false. With the data you gave me, my methodology is 100% right
It’s 3578 because that proves the account is in theory
The solution to this system of inequalities has to fall within the shaded area. The only point that falls in this area is (2, 0).
