Inscribe triangle RST in the square with dimensions 4×4, as shown in the figure.
from the area of this square, 4*4=16, we remove the triangles with dimensions
3×4, 2×1 and 2×4, whose side lengths are shown in the figure, and we are left with the area of triangle RST.
so
units squared
similarly,
units squared
Thus, the areas are equal.
Answer:
The monthly payment will be $531.12
Step-by-step explanation:
Consider the provided information.
After paying $5,000 down payment you need to pay:
$29,000-$5,000=$24,000
APR is 2.99% or APR = 0.299%
Therefore, 
n = 48
We can calculate the monthly payment by using the formula:
Where P is the monthly payment, PV is the present value, r is the rate per period and n is the number of period.
Substitute the respective values in the above formula we get,
Hence, the monthly payment will be $531.12
Answer:
B: $13.75
Step-by-step explanation:
5.5% of $250 = $13.75
Therefore, the simple interest is $13.75.
Answer:
So then the best option is:
a. 7.32
Step-by-step explanation:
Previous concepts
Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".
The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"
If we assume that we have 
groups and on each group from 
we have 
individuals on each group we can define the following formulas of variation:
And we have this property
Where SST represent the total sum of squares.
The degrees of freedom for the numerator on this case is given by 
where k =3 represent the number of groups.
The degrees of freedom for the denominator on this case is given by 
.
And the total degrees of freedom would be 
From the info given we know that 
And 
From definition the F statisitc is defined as:
So then the best option is:
a. 7.32
