It seems logical that restaurant chains with more units (restaurants) would have greater sales. Ca 5 n we predict sales by measu
svetoff [14.1K]

Answer:

Step-by-step explanation:

Hello!

A regression model was estimated in order to test if the number of units of a restaurant chain affecta the sales of said restaurant chains.

The estimated model is:

Y= a + bX

Where

Y: is the sales of a restaurant chain

X: number of units of a restaurant chain

Looking at the computed data, the estimated coefficients are:

a= 4.633131413

b= 0.439724072

The correct regression equation to predict Sales based on Units, according to this analysis, is..

Y= 4.63 + 0.44X

I hope it helps!

Translate the figure 6 units up. Then decide if each statement about translated figures is true or false.
olga2289 [7]

Answer:

False, True, True, True

Step-by-step explanation:

The pre-image and image are the exact same size and shape: meaning that they are congruent. Because they are congruent, it is impossible for the side lengths to be different from each other. The final side lengths are both parallel and the same as the original. Hope that helps!! :))

Mortgage (monthly)
rodikova [14]

Answer:

Amount you could save per month  if you take 25% of your discretionary monies and put it in a savings account is  $209.68

Step-by-step explanation:

Expense                                    Amount                 Per Month Expenses  

Mortgage (monthly)                   $985.64                     $985.64

Cell phone (monthly)                    $58.30                       $58.30        

Groceries (twice a month)             $154.00                $308.00                

Clothing (monthly with                        $180.00               $180.00

25% job–related )                        

Water & electric (monthly)                    $128.40                 $128.40    

Weekly dinner & movie                         $55.00                 $220.00

Property taxes (6 months)                  $684.80           $114.133            

Car insurance (quarterly)                  $330.00           $110.00

Groceries multiplied by 2 as you buy them twice a month. Dinner and movie on weekly basis, so you multiply it by 4. Car Insurance you pay for 4 quarters. 1 quarter has 3 months so, you divide 330 by 3, to find the amount paid per month. Rest of the data is monthly expense.

So, your total fixed expense per month = $ 2104.473.

Discretionary income = Income - Expense.

Discretionary income = $ 2,943.20 - $ 2104.47

                                    = $ 838.73

Now, you are saving 25% of the discretionary income into your account. So, 25 % of $838.73 is your saving

Amount you could save = 25 % of $838.73

                                    = 0.25 x $838.73

                                    = $209.68
