The owner of Original Italian Pizza restaurant chain wants to understand which variable most strongly influences the sales of hi

s specialty deep-dish pizza. He has gathered data on the monthly sales of deep-dish pizzas at his restaurants and observations on other potentially relevant variables for each of several outlets in central Indiana. These data are provided in the file P10_04.xlsx. Estimate a simple linear regression equation between the quantity sold (Y) and each of the following candidates for the best explanatory variable: average price of deep-dish pizzas (X1), monthly advertising expenditures (X2), and disposable income per household in the areas surrounding the outlets (X3). Round your answers for intercept coefficients to the nearest whole number and slope coefficients to two decimal places, if necessary. If your answer is negative number, enter "minus" sign.

The linear regression model gives mathematical relationship between two variables, the dependent<em> and </em>independent<em> variables</em>. The linear models between the <em>quantity sold and the variables average price, disposable income and monthly advertising are</em> :

  • <em>y = - 4713.46x + 117763</em>
  • <em>y = 2.94x - 58384</em>
  • <em>y = - 1.75x - 32655</em>

To create a linear model using the data given, we use technology such as a excel or a linear regression calculator :

The linear model created using a linear regression calculator between each of the independent variables and quantity sold are :

<u>Average price of deep - dish and Quantity sold :</u>

  • Average price of deep - dish pizza(X)
  • Quantity sold (Y)

y = - 4713.46x + 117763

<u>Disposable income and Quantity sold</u> :

  • Disposable income (X)
  • Quantity sold (Y)

y = 2.94x - 58384

<u>Monthly advertising expenditure and Quantity sold</u> :

  • Monthly advertising cost (X)
  • Quantity sold (Y)

y = - 1.75x - 32655

A company plans to enclose three parallel rectangular areas for sorting returned goods. The three areas are within one large rec
Svetlanka [38]

Answer:

The largest total area that can be enclosed will be a square of length 272 yards.

Step-by-step explanation:

First we get the perimeter of the large rectangular enclosure.

Perimeter of a rectangle =2(l + w)

Perimeter of the large rectangular enclosure= 1088 yard

Therefore:

2(L+W)=1088

The region inside the fence is the area

Area: A = LW

We need to solve the perimeter formula for either the length or width.

2L+ 2W= 1088 yd

2W= 1088– 2L

W = \frac{1088-2L}{2}

W = 544–L

Now substitute W = 544–L into the area formula

A = LW

A = L(544 – L)

A = 544L–L²

Since A is a quadratic expression, we re-write the expression with the exponents in descending order.

A = –L²+544L

Next, we look for the value of the x coordinate

L= -\frac{b}{2a}

L= -\frac{544}{2X-1}

L=272 yards

Plugging L=272 yards into the calculation for area:

A = –L²+544L

A(272)=-272²+544(272)

=73984 square yards

Thus the largest area that could be encompassed would be a square where each side has a length of 272 yards and a width of:

W = 544 – L

= 544 – 272

= 272 yards
