<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
Note: Shape does not change.</span>
X2+5x=0
7x+0
divide both sides by 7
7 divided by 0 is 0
x=0
0=0
Answer:
10
Step-by-step explanation:
X = -1 so, we have:
3·1² + 1
3² + 1
9 + 1
