Which equation is a quadratic model for the data set? hint: use a graphing calculator or a spreadsheet program. data table

Equation for the quadratic model for the data set is;

Step-by-step explanation:

A Quadratic regression is the process of finding the equation of the parabola that best fits the set of data.

An equation is in the form of: where a≠0.

You just enter the x-coordinates and y-coordinates in your graphing calculator and

then do a quadratic regression.

The equation of the parabola that best approximates the points is

:

Now, plot the graph of the above equation as shown below in the figure.

Also you can see that the value for the above data is, 0.994

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
