<span>Answer: Skewed to right with mean 0 and S.D. 1
Explanation: Let's assume the z-scores as a linear transformation.
then z=(x-mean)/S.D. = (x-30)/15
z(mean) = (30-30)/15= 0
z(sigma) = 15/15 = 1

Answer:
f(5) = -8
Step-by-step explanation:
x -4 -1 3 5
f(x) -2 5 4 -8
f(5) is the value of f(x) when x = 5
f(5) = -8
Answer:
a. sin 30* = sin 150*
b. sin 1* = sin 179*
a. cos 340* = cos 20*
b. cos 260* = cos 100*
Step-by-step explanation:
sine is symmetrical around x = 90*
cosine is symmetrical around x = 180*
* means degree sign of course.
