Solution
The z-score, also referred to as standard score, z-value, and normal score, among other things, is a dimensionless quantity that is used to indicate the signed, fractional, number of standard deviations by which an event is above the mean value being measured. Values above the mean have positive z-scores, while values below the mean have negative z-scores.
Mean is $650
Standard deviation = $50

Step-by-step explanation:
hope this helps!
Find gradient by changing form of equation: y = 2/3x + 4. Gradient is 2/3.
Find y intercept of other line by substituting the coordinates: -8/3
Use information to write out equation of line: y= 2/3x - 8/3
Convert to standard form: -2x + 3y = 8.
Hope this helps :)
The answer would be C, some number divided by 3.
A represents addition, y + 3
B represents multiplication, y * 3
D represents subtraction, y - 3
