The table displays data for Nutrition Guides of a single serving of particular foods. Assuming there exists a correlation betwee

n Calories and Fat Grams, find a linear regression model that determines approximate Fat Grams (y) as a function of Calories (x).
y=0.056x - 1.759


y=0.054x - 2.105


y=14.211x + 68.070


y=13.019x + 85.966

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.)

Ahmad drove 360miles in 5hours.<br> At the same rate, how long would it take him to drive 864miles?
AVprozaik [17]

It will take Ahmad 12 hours to drive 864 miles

Step-by-step explanation:

  • Step 1: Find the speed of Ahmad.

Distance = 360 miles

Time = 5 hours

⇒ Speed = Distance/Time = 360/5 = 72 miles/hour

  • Step 2: Find the time required to drive 864 miles

⇒ Time = Distance/Speed = 864/72 = 12 hours

The midpoint of AB is (3,2). If point is is located at(8,4) what are the coordinates of point B
Dmitry [639]

Step-by-step explanation:

8-3 = 5,

3-5 = -2 = the x coordinate of B

-2-4 =-6,

-2-6 =-8 = the y coordinate of B

(-2,-8) is the point B

A is 5 to the right of the midpoint, so B is 5 to the left of the midpoint

A is 6 up from the midpoint so B is 6 down from the midpoint
