Answer:
2:1
Step-by-step explanation:
average age of both = 40
average age of teachers = 35
average age of professors = 50
35 + 35 + 50 = 120
120 / 3 = 40
Answer:
The correct answer is: x = 35 gallons
Step-by-step explanation:
We will make equation for this problem:
20 x + 70 · 15 = (x + 15) · 35 => 20 x + 1050 = 35 x + 525 =>
35 x - 20 x = 1050 - 525 => 15 x = 525 => x = 525/15 = 35 gallons
x = 35 gallons
God with you!!!
32g/m = 32*60 = 1920 gallons per hour
1 gallon = 4 quarts
1920 *4 = 7680 quarts per hour
Answer:
The degrees of freedom for the model on this case is given by where k =1 represent the number of variables.
The degrees of freedom for the error on this case is given by . Since we know we can find N.
And the total degrees of freedom would be
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"
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.
Solution to the problem
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 =1 represent the number of variables.
The degrees of freedom for the error on this case is given by . Since we know we can find N.
And the total degrees of freedom would be
