xz_007 [3.2K]

Answer:

The linear regression model that will determine approximate Fat Grams (y) as a function of Calories (x) is given by

 y = 0.054 x - 2.105

Hence the correct option is B.)

Step-by-step explanation:

Step 1: Find X⋅Y and  as it was done in the table below.

Step 2: Find the sum of every column:

ΣX = 1560,  ΣY = 67,     ΣX.Y = 14860 ,   ∑(\textbf{X}^{2}) =  337600

Step 3: Use the following equations to find a and b:

a  =  = -2.105

b = \frac{n.\sum{XY}  -   \sum{X}.\sum{Y}}{n.\sum{(X^{2})}- (\sum{X})^{2} } = 0.054

Step 4: Substitute a and b in regression equation formula

y  = a + b⋅x= −2.105 + 0.054⋅x

The linear regression model that will determine approximate Fat Grams (y) as a function of Calories (x) is given by

 y = 0.054 x - 2.105

Hence the correct option is B.)

Can someone show me how to write the standard form of the line that contains a slope of 2/3 and passes through the point (1, 1)?
8090 [49]

Answer:

\large\boxed{y=\dfrac{2}{3}x+\dfrac{1}{3}\qquad\text{slope-intercept form}}\\\\\boxed{y-1=\dfrac{2}{3}x-\dfrac{2}{3}\qquad\text{point-slope form}}\\\\\boxed{2x-3y=-1\qquad\text{standard form}}

Step-by-step explanation:

\text{The standard form:}\ Ax+By=C

\text{The point-slope form:}\\\\y-y_1=m(x-x_1)\\\\m-slope\\\\\text{We have the slope}\ m=\dfrac{2}{3}\ \text{and the point}\ (1,\ 1).\ \text{Substitute:}\\\\\underline{y-1=\dfrac{2}{3}(x-1)}\qquad\text{use the distributive property}\\\\y-1=\dfrac{2}{3}x-\dfrac{2}{3}\qquad\text{add 1 to both sides}\\\\\underline{y=\dfrac{2}{3}x+\dfrac{1}{3}}

y=\dfrac{2}{3}x+\dfrac{1}{3}\qquad\text{multiply both sides by 3}\\\\3y=2x+1\qquad\text{subtract 2x from both sides}\\\\-2x+3y=1\qquad\text{change the signs}\\\\\underline{2x-3y=-1}
