Nookie1986 [14]

Answer: $4$

Step-by-step explanation:

Substitute the value of the variable into the equation and simplify.

I evaluate and found the exact value: 4

$( h -3 )2 \\h = 5$

If you want me to Find the Linearization at h=5: Use the formula $L(x)=f(a)+f'(a)$ $(x-a)$ to find the linearization.

Answer(Find the Linearization at h=5): $L(x)=2x-6$

Use the following table for questions 11-13.A baseball manager believes a linear relationship exists between the number of Home

The regression equation of Y on X is given by the following formula:

$Y-\bar{Y}=b_{yx}(X-\bar{X})$

Where byx is given by the formula:

$b_{yx}=\frac{N\sum^{}_{}XY-\sum^{}_{}X\sum^{}_{}Y}{N\sum^{}_{}X^2-(\sum^{}_{}X)^2}$

Where N is the number of values (N=8). We need to find the sum of X values, the sum of Y values, the average of X, the average of Y, the sum of X*Y and the sum of X^2.

The table of values is:

The values we need to know are on the following table:

By replacing the known values in the formula we obtain:

$\begin{gathered} b_{yx}=\frac{8\cdot26125-167\cdot995}{8\cdot4649-(167)^2} \\ b_{yx}=\frac{209000-166165}{37192-27889} \\ b_{yx}=\frac{42835}{9303} \\ b_{yx}=4.6 \end{gathered}$

Now, the average of X and Y is the sum divided by N, then:

$\begin{gathered} \bar{X}=\frac{167}{8}=20.87 \\ \bar{Y}=\frac{995}{8}=124.37 \end{gathered}$

Replace these values in the formula and find the regression equation as follows:

$\begin{gathered} Y-124.37=4.6(X-20.87) \\ Y-124.37=4.6X-4.6\cdot20.87 \\ Y=4.6X-96.11+124.37 \\ Y=4.6X+28.26 \end{gathered}$

The answer is a) y=4.6x+28.26

Fantom [35]

You would first find out the greatest common factor of 204 and 306 which is 102

204 divided by 102 which is 2
306 divided by 102 which is 3

So the answer is 2/3
