All Real Numbers are Solutions
I am sorry, but I think that the question is cut off. Perhaps you can re-post it for us to see it completely? I would be happy to help! :)
X = 2/3
Y= -1/2
Here you have solutions of two equation
Answer:
0.0668
Step-by-step explanation:
Assuming the distribution is normally distributed with a mean of $75,
with a standard deviation of $12.
We can find the z-score of 78 using;
Using our normal distribution table, we obtain the area that corresponds to 0.25 to be 0.9332
This is the area corresponding to the probability that, the average is less or equal to 78.
Subtract from 1 to get the complement.
P(x>78)=1-0.9332=0.0668
