Answer:
0.00045 
Step-by-step explanation:
450 
⇒
1 = 0.000001
= 450 = 450 × 0.000001 = 0.00045
Answer:
proportional
down by 50

Answer:
it's being reduced by .25 cents I would think
Step-by-step explanation:
2*.25=1.75
2-1.75=.25
Mean, x_bar = 1518
Standard deviation, sigma = 325
Range required: 1550 ≤ X ≤ 1575
Z = (X - x_bar)/sigma
Z1 = (1550-1518)/325 ≈ 0.1
Z2 = (1575-1518)/325 ≈ 0.18
From Z tables,
P(Z1) = 0.5398
P(Z2) = 0.5714
P(1550≤X≤1575) = P(Z2) - P(Z1) = 0.5714 - 0.5398 = 0.0316
The correct answer is C.
Answer:
The basic equation to use is y = abx but in this case the x is actually time, so let's use "t" as the variable. So y = abt
Also, the a is the initial value (starting point) so in this case, that is 3400. So, y = 3400bt
The b in this case is given by the interest rate. So convert 8.25% into a decimal (0.0825) but since this is growing by .0825, we actually need to add 1 to that decimal, so b = 1 + 0.0825 = 1.0825. That make the equation: y = 3400(1.0825)t.
But t = 25 years, so: y = 3400(1.0825)25
Just plug that into your calculator to get the value
