C.)
We can substitute numbers for the variables to make them true. We'll have a=2, b=1, and c=-1. We see that 2(-1) > 1(-1) is false since -2 is not greater than -2, so B is incorrect. However, when we do 2(-1) < 1(-1), this is true since -2 is less than -1, so C is correct. Hope this helps!

<span>The correct answer is C: 80 shares of the stock and the price of each share is $40.</span>
The coordinates of points A, B, and C are (5,4), (-2,1) , and (4,-4), respectively. Which point , B or C, is closer to point A?

The answer is B. To see this visually, you have to plot the points on a graph.
The Z-score (z) is calculated according to the formula: z = (x - μ) / σ
Where: x is the raw score value, μ is the mean of the population, σ is the standard deviation of the population.
x = 80, μ = 5, σ = 4
z = (80 - 5) / 4
z = 75 / 4 = 18.7500
Z-score is 18.7500
