Answer:
And
The difference is that MSA takes incount the variation between the groups and the grand mean, and the MSW takes in count the variation within groups respect to the mean of each group
.
Step-by-step explanation:
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
The degrees of freedom for the numerator on this case is given by where k 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
We can find the
And
The difference is that MSA takes incount the variation between the groups and the grand mean, and the MSW takes in count the variation within groups respect to the mean of each group
.
And the we can find the F statistic
Answer:
11; 35
Step-by-step explanation:
width is x
length is 3x+2
perimeter is 2x+2(3x+2)=92
2x+6x+4=92
8x+4=92
8x+4-4 = 92-4 (subtract 4 from both sides)
8x=88
x=11 (by dividing both sides by 8)
11---> width
3times11+2=35 is length
Let
be the width of the rectangle.
Since the perimeter of this rectangle is 100, then the height of the triangle must be
Both width and height are positive numbers, so we must have
There are infinity real numbers that are greater than zero and less than 50. Therefore, there are infinity rectangles having a perimeter of 100.
width:
<span>
</span>height:
(You can pick any real number between
and
for the
value )
Answer:
p=x−7
Step-by-step explanation:
Let's solve for p.
px=x^2−7x
Step 1: Divide both sides by x.
px/x=x^2−7x/p
=x−7
Answer:
p=x−7
