Answer:

-84i - 12i

Step-by-step explanation:

The distributive property is: a(b+c) = ab + ac

In this case, we have -6i(-14i+2)

-6i = a

-14i = b

2 = c

-6i(-14i+2) = -6i(-14i) + -6i(2)

= 84i^2 - 12i

= -84 - 12i

Answer:

84-12i

Step-by-step explanation:

-6i(-14i+2).

since we can’t add the numbers in the (), we multiply -6i to 14i and 2.

minus times minus equals positive +.

minus times positive equals minus, same with positive times minus.

positive times positive numbers equal positive.

with this, -6i times -14i equals +84 although we don’t need to put the +.

then -6i times +2 equals -12i. We have to put the i in 12i because the i is in -6i, plus that is what we are multiplying with. So the equation would be..

+84+(-12i)

= 84 - 12i

Answer:

df_{den}=df_{between}=N-K=17-3=14.

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 3 groups (A,B,C) and on each group we have sample of size (6,5,6) respectively , on each group we can define the following formulas of variation:  

SS_{total}=\sum_{j=1}^p \sum_{i=1}^{n_j} (x_{ij}-\bar x)^2  

SS_{between}=SS_{model}=\sum_{j=1}^p n_j (\bar x_{j}-\bar x)^2  

SS_{within}=SS_{error}=\sum_{j=1}^p \sum_{i=1}^{n_j} (x_{ij}-\bar x_j)^2  

And we have this property  

SST=SS_{between}+SS_{within}  

The degrees of freedom for the numerator on this case is given by df_{num}=df_{within}=k-1=3-1=2 where k =3 represent the number of groups.

The degrees of freedom for the denominator on this case is given by df_{den}=df_{between}=N-K=17-3=14.

And the total degrees of freedom would be df=N-1=17 -1 =16

On this case the correct answer would be 2 for the numerator and 14 for the denominator.
