suppose a normal distribution has a mean of 79 and a standard deviation of 7. What is P(x > or = 93)?

okay so im thinking it could be P(X >= 86) =  P (Z  >= 1) = 0.1587 from the Z-scores table

Step-by-step

so im not sure but this could be right

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
