Answer:
<h2>D. {-4, 1, 0, 2, 7}</h2>
Step-, by-step explanation:
For any order pairs (x, y), x is an element of a Domain and y is an element of a Range.
For {(7, -3); (-4, 2); (-1, 0); (2, -4); (0, -6)}
the set {7; -4, -1, 2, 0} is a Domain.
Answer: Marc should deposit $2766
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
A = $3500
r = 8% = 8/100 = 0.08
n = 2 because it was compounded 2 times in a year.
t = 3 years
Therefore,
3500 = P(1+0.08/2)^2 × 3
3500 = P(1+0.04)^6
3500 = P(1.04)^6
3500 = 1.2653P
P = $2766
Answer:
The margin of of error for a 95% confidence interval for the population mean is of 1.39 years.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
That is z with a pvalue of 
, so Z = 1.96.
The margin of error is:
In which 
is the standard deviation of the population and n is the size of the sample.
Population standard deviation of 3 years
This means that 
Sample of 18 voters
This means that 
Margin of error:
The margin of of error for a 95% confidence interval for the population mean is of 1.39 years.
