Answer:
Step-by-step explanation:
To add two fractions, they must have the same denominator.
LCD = 8
You can convert the fractions to the decimals.
Answer:
134 cubic centimeters
Step-by-step explanation:
The extended part is basically the volume of HALF A SPHERE.
First, the volume of full sphere is:
Hence, the half sphere volume would be:
We know the diameter is 8, radius is HALF OF THAT, so
Radius = 8/2 = 4
Substituting, we find (remembering to use 3.14 as pi):
To the nearest cubic centimeter, the answer is:
134 cubic centimeters
Answer:
N=27 participants
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"
When we conduct a multiple regression we want to know about the relationship between several independent or predictor variables and a dependent or criterion variable.
If we assume that we have independent variables and we have individuals, we can define the following formulas of variation:
And we have this property
The degrees of freedom for the model on this case is given by where k =2 represent the number of variables.
The degrees of freedom for the error on this case is given by . Sinc we know k we can find N.
And the total degrees of freedom would be
On this case the correct answer would be N=27 participants
