Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value. A low standard deviation means that most of the numbers are close to the average. A high standard deviation means that the numbers are more spread out.
52,000 • .047 = 2,444
2,444 = decrease in dollars
52,000-2,444 = 49,556
49,556 = price of next model

Answer:
Distributive property of equality
Step-by-step explanation:
The first thing to do in an equation is to distribute.
Parallel lines has equal slopes. Hence slope of line = -1/2
equation of line is (y - y1) = -1/2(x - x1)
y - (-6) = -1/2(x - 4)
y + 6 = -1/2x + 2
y = -1/2x + 2 - 6
y = -1/2x - 4
