Answer:
C
Step-by-step explanation:
i took test
90 is the outlier
for future reference, outliers are numbers much larger or much smaller than the other numbers in a set
for example
2,3,4,21,6
or 90,87,94,12,99
The answer is 5b²/6c
Ok so you just have to simplify
15/18 = 5/6 (cause 3*5=15 and 3*6=18)
Then you do as the picture above says.
I just took the test yesterday and passed
1. First one is False second one is true
2. the points are -2,-3 1,6 2,9
3. -3
4. 1
