Answer:
$74,600
Step-by-step explanation:
-Given the probability is 2.5%, mean=$55,000 and standard deviation= $10,000
-We find the z value of 2.5%
Hence, the minimum amount of income to be in the top 2.5% is $74,600
Answer:
(a variation of) vertex form
Step-by-step explanation:
For vertical scale factor "a" and vertex (h, k), the vertex form of the equation for a parabola can be written as ...
y = a(x -h)^2 +k
If k is subtracted from this equation, an alternate form is ...
y -k = a(x -h)^2
This latter version of vertex form is the form your equation has, where ...
- a = 8
- (h, k) = (-7, -20)

Exponents have the highest priority, so we evaluate 3 cubed first:
Next, we have to solve parenthesis first: we have 27-8 = 19, so the expression becomes
Multiplications and divisions have the same priority, so we perform them as they appear: , so the expression becomes
