If f(x) = 3x^2 and g(x) = x+2 find (f•g)(x)

Alex777 [14]

Answer:

(f*g)(x) = 3x^3 + 6x^2

Step-by-step explanation:

Since we are looking for the result of multiplying the equations (f*g), we must multiply the right sides together

(f*g)(x) = (3x^2)(x+2)

To get from here to the solutions, we must multiply the first term by all parts in the second term

3x^2 * x = 3x^3

3x^2 * 2 = 6x^2

from there, just put them back in the equation

(f*g)(x) = 3x^3 + 6x^2

When utilizing ANOVA, what does the between group sum of squares measure?

zhenek [66]

Answer:

b. The sum of the squared deviations between each group mean and the mean across all groups

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"

Solution to the problem

If we assume that we have $p$ groups and on each group from $j=1,\dots,p$ we have $n_j$ individuals on each group we can define the following formulas of variation:
