Calculate the amount of money you'll have at the end of the indicated time period, assuming that you earn simple interest. You
1 answer:
Answer:
The amount of money you'll have at the end of the years is 6460 dollars
Step-by-step explanation:
The total principal sum of money deposited = dollars
The annual rate of interest is %
The time period for which the amount is invested years
As we know
where A is the amount after 20 years
P is the principal sum of money
r is the rate of interest and
t is time period in years
Substituting the given values in above equation, we get -
dollars

Answer:
144ft^2
Step-by-step explanation:
since it's a kite, there are two pairs of congruent (exactly the same shape) triangles
bc of this you can find one triangle from each pair and double it
e.g.
so you would do 2(24+48)=144

Step-by-step explanation:
For this case we can create the following table
Interval Frequency (f) Midpoint(xi) xi *f xi^2* f
0-499 9 249.5 2245.5 560252.3

For this case we can calculate the sample mean with this formula:
And for the sample variance we can use the following formula:
And if we replace we got:
And the deviation is just the square root of the sample variance and for this case is:
Answer:
Step-by-step explanation:
In order to write the equation of this line, we need to pick 2 points on the graph where the line goes right through the intersection of the grids. Actually, you only need 1 of these, because the line goes through at (0, 15). Another point then can be (6, 6). Locate this point so you know what I means when I say that the line goes right through where the grids intersect at x = 6 and y = 6 (as opposed to somewhere in the middle of one of these grids). Find the slope between these 2 points:
Since there's only one choice with that slope, that is the choice you want.
