Answer:
9:24 simplifies to 3:8
Step-by-step explanation:
3:8
24/8=3
3*3=9
last night he did 9 pull ups and 24 situps
Answer:
The degrees of freedom for the numerator on this case is given by
where k =14 represent the number of groups.
The degrees of freedom for the denominator on this case is given by
.
And the best option would be:
d. 14 and 240.
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
independent variables 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 =14 represent the number of groups.
The degrees of freedom for the denominator on this case is given by
.
And the best option would be:
d. 14 and 240.
Answer:
1/6 cubic unit
Step-by-step explanation:
Each plane describes the boundary of a triangular pyramid in the first octant. If we consider the x-y plane to be the base, that base will have an area that is 1/2 the product of the x- and y-intercepts. The height of the pyramid will be the z-intercept, so the volume is ...
V = (1/3)Bh = (1/3)((1/2)(x-intercept)(y-intercept))(z-intercept))
= (1/6)(x-intercept)(y-intercept)(z-intercept)
__
We can write the equation of each plane in intercept form by dividing by the constant on the right:
x/(x-intercept) + y/(y-intercept) + z/(z-intercept) = 1
1st plane: x/1 + y/1 + z/1 = 1 . . . . . enclosed volume = (1/6)(1)(1)(1) = 1/6
2nd plane: x/1 + y/1 + z/2 = 1 . . . enclosed volume = (1/6)(1)(1)(2) = 2/6
The difference between the volumes enclosed by the planes is the volume of the region between them, so is ...
V = (2/6) -(1/6) = 1/6 . . . . cubic units
_____
We note that the x- and y-intercepts of both planes are the same, so the volume is that of a triangular wedge having an edge on the line x+y=1 in the plane z=0.
Answer:
The y-intercept is positive 15
