The maximum number of microwave ovens the two employees can take on the elevator is 7.
<h3>How to find the maximum number of microwave ovens the two employees can take on the elevator?</h3>
To solve the question, we have to find the simple equation showing the relationship between all the weights an the maximum weight the elevator can carry
Let
- x = number of microwave ovens
Since the micro wave weighs 45 pounds, the total weight of microwave ovens is W = 45x.
Also, there are 20 televisions on the elevator. If each television weighs 85 pounds, the total weight of televisions is W' = 20 × 85 = 1700 pounds
Also, the weight of the equipment and the two employees is W" = 400 pounds.
Since the maximum weight on the elevator is 2400 pounds, we have that the required simple equation is
W + W' + W" = 2400
45x + 1700 + 400 = 2400
45x + 2100 = 2400
45x = 2400 - 2100
45x = 300
x = 300/45
x = 6.67
x ≅ 7
So, the maximum number of microwave ovens the two employees can take on the elevator is 7.

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
