The best measure of center tendency for this set of data would be the median. It is the best measurement because the data set has an outlier. The outlier is the 30. So to find the median we first order the data set and then find out if the set is an even or odd set. This set is even so we just chose the middle number. If the set was even, we would add the two center number and divide them by 2.
3, 3, 4, 4, 4, 5, 5, 5, 30
The center tendency = 4
C=(-10;5). If you want an explanation I would be happy to explain it
27 is how much kids did the survey because I added all the fractions together like how the question did 3/5 which is 3 × 5 = 15
Step-by-step explanation:
7x + 3x + 90= 180
10x= 180-90
10x= 90
x= 90/10
x=10
I’m not sure what happened while you were writing this, but if I’m reading it right, “My” has 18 books. If “My” has 3 times as many as 6, that also means 3 times 6, which is 18.
