Answer:

Step-by-step explanation:

divide both by 2

40 percent of 100 is 40

80/200 = .4 or .40 which is 40%

Assumptions of a regression model can be evaluated by plotting and analyzing the ____________

Gala2k [10]

The assumptions of a regression model can be evaluated by plotting and analyzing the error terms.

Important assumptions in regression model analysis are

There should be a linear and additive relationship between dependent (response) variable and independent (predictor) variable(s).
There should be no correlation between the residual (error) terms. Absence of this phenomenon is known as auto correlation.
The independent variables should not be correlated. Absence of this phenomenon is known as multi col-linearity.
The error terms must have constant variance. This phenomenon is known as homoskedasticity. The presence of non-constant variance is referred to heteroskedasticity.
The error terms must be normally distributed.

Hence we can conclude that the assumptions of a regression model can be evaluated by plotting and analyzing the error terms.

First, you should solve for $f(2x)$ , which equals $2*(2x)=4x$ . Now, solve the integral of $f(2x)$ = $2*(2x)=4x$ , to get that $\int\ {(f(2x)=4x)} \, dx= 2x^2$ . You can check this by taking the integral of what you got. Now by the Fundamental Theorem $\int\limits^2_0 {4x} \, dx=[2x^2] ^{2}_{0}=2(2)^{2}-2(0)^2=8$ .

This should be the answer to your question, if I understood what you were asking correctly.

Answer:

<C=26

<B=48

<D=106

<F=42

Step-by-step explanation:

I labeled all the angles to help this make more sense :)

So first we find <C, which is supplementary to <E so just do 180-154=26
