Answer:
The correct option is 4. Neither A nor B represents a function.
Step-by-step explanation:
The given sets of ordered pairs are


A set of ordered pairs represents a function if there exist unique outputs for all inputs. It means for each values of x there exist, a unique value of y.
In set A the value of y-coordinates are -5 and 7 at
.
At x=8, there exist more than one value of y, so the set A is not a function.
In set B the value of y-coordinates are -4 and -2 at
.
At x=7, there exist more than one value of y, so the set B is not a function.
Therefore neither A nor B represents a function and option 4 is correct.
Answer:

Step-by-step explanation:
Let's write the left hand side as a negative power, and 9 as a power of 3:
At this point, for the equality to still stand, the exponents have to be equal:

Area = 4 cm * 8 cm = 32 cm²
20 get a ball because 60 divided by 3 equal 20 ab 15 get a ball because 60 divided by 4 equals 15
ok for number 2.) 2+8+1+5+1+3+1+7+5+4+3+1=41 and 41 divided by the number of number which is 12= 3.41666666667
the mean for number 2 is 3.41666666667.
for the median you put the number from least to greatest, like so:
1, 1, 1, 1, 2, 3, 3, 4, 5, 5, 7, 8.
The middle is 3 and 3 so 3+3 divided by 2 is 6 so the median is 6.
I cant do mode but range is 8-1 divided by 2
