Answer: 28.4
Step-by-step explanation:
Given : A set of data with a mean of and a standard deviation of is normally distributed.
Now, the value that is –2 standard deviations away from the mean is given by :-
Hence, the value that is –2 standard deviations away from the mean. = 28.4
(x + 1)2 = 3(y-4)
(y-4)2 = 12(x + 1)
(y-2)2 = -3(x – 4)
(y-4)2 = –12(x - 2)
