Answer:

<u>The original price of the coat was £ 275</u>

Step-by-step explanation:

1. Let's review all the information given for solving this question:

Sale price of the coat = £ 220

Discount from the original price = 20%

2. Let's find the original price of the coat

Original price of the coat = x

Sale price of the coat = £ 220

Sale price of the coat = x - 20%x

220 = x - 0.2x

220 = x - 2x/10 (0.2 = 2/10)

2,200 = 10x -2x (Multiplying by 10 at both sides)

2,200 = 8x

2.200/8 = 8x/8 (Dividing by 8 at both sides)

275 = x

<u>The original price of the coat was £ 275</u>

Using the same data set, four models are estimated using the same response variable, however, the number of explanatory variable
kirill [66]

Answer:

Model A

Step-by-step explanation:

Given the table :

___________M 1 ____ M 2 ____ M 3 ____M 4

Multiple R _ 0.993 ___ 0.991 ___0.936__ 0.746

R Square __0.987___ 0.982 ___0.877 __0.557

Adj R² ____ 0.982___ 0.978 __ 0.849 ___0.513

S E_______ 4,043 __ 4,463 ___11,615 __20,878 Observations_ 12 _____ 12 _____ 12 ____12

Based on the detains of the model given, we could use the R value, R² and standard error values to evaluate the performance of the different models.

The best model will be one with Correlation Coefficient (R value) closet to 1. The model with the highest R value will also have the highest Coefficient of determination, R² value. The a best model is one which has a low a standard error value.

From the table, Model A has the highest R and R² values. It also has the lowest standard error value. Hence, we can conclude that model A provides the best fit.

Which route must use all of the vertices of a vertex-edge graph? (Check all that apply.)
zlopas [31]

An Euler path, in a graph or multi graph, is a walk through the graph which uses every edge exactly once. An Euler circuit is an Euler path which starts and stops at the same vertex. Our goal is to find a quick way to check whether a graph (or multi graph) has an Euler path or circuit.
