Answer:
The ordered pairs of A and C are not functions
Step-by-step explanation:
To determine if the ordered pairs are a function you look at the x values to see if they repeat. You don't want one input(x values) to lead to two outputs(y values). This would mean that you are never sure which output you will get.
In the answer A the x value "2" repeats, in the answer C the x value "1" repeats thus not making them functions.

Answer:
Katrina got 86 in her test
Step-by-step explanation:
given
mean = 80
standard deviation = 3
z-score = 2
Let score of Katrina = x
Recall z-score is calculated by
z-score = (x-mean) / standard deviation
substitute values and solve for x
2 = (x-80)/3
x-80=6
x = 86
