X-3=-6
if you take away 3 from a number, you will get -6
x=-3
The score of 96 is 2 standard deviations above the mean score. Using the empirical rule for a normal distribution, the probability of a score above 96 is 0.0235.
Therefore the number of students scoring above 96 is given by:
Answer:
Step-by-step explanation:
9-4(x-y)=2x+6
9 - 4x + 4y = 2x + 6
9 + 4y = 6x + 6
4y = 6x - 3
y = 3x/2 - 3/4
Answer:
