The formula for simple interest is A = P(1+rt)
Where P is the principal ( amount of money deposited)
R is the interest rate
t is the amount of time
A is the total of the principal and interest.
Using the information given in the problem:
A = 4200(1+0.0325*3)
A = 4200(1 + 0.0975)
A = 4200(1.0975)
A = 4609.50
Now subtract the principal from the total to find the amount of interest:
4609.50 - 4200 = 409.50
Amount of interest = $409.50
Answer:
Step-by-step explanation:
given that the U.S. Department of Housing and Urban Development (HUD) uses the median to report the average price of a home in the United States.
We know that mean, median and mode are measures of central tendency.
Mean is the average of all the prices while median is the middle entry when arranged in ascending order.
Mean has the disadvantage of showing undue figure if extreme entries are there. i.e. outlier affect mean.
Suppose a price goes extremely high, then mean will fluctuate more than median.
So median using gives a reliable estimate since median gives the middle price and equally spread to other sides.

Answer:
The vertex of the function is 
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
It's vertex is the point 
In which
Where
If a<0, the vertex is a maximum point, that is, the maximum value happens at 
, and it's value is 
.
f(x) = x² - X + 2.
Quadratic equation with 
So
The vertex of the function is
