Answer:
Step-by-step explanation:
The area of the square is 3 units by 3 units. because the area of a square is side length squared.
side length = 3
side length^2 = 3 * 3 = 9
The area of a circle is much harder to reason out. You could start with the area of a square and use the diameter is 3 units. But the corners are rounded and you don't know off hand what the area of one of them is, let alone all 4. You are given a formula for circles area, but you have no real idea what the formula actually means. Does it take the corner area into account? At the beginning levels, we don't know.

Step-by-step explanation:
1) Lets form the regression equation from the data results
Size = -1.633+ 0.4485*FamilyIncome + 4.2615*FamilySize - 0.6517*Education
-1.633+ 0.4485*40+ 4.2615*4 - 0.6517*13 =24.88
2) For the model to be reasonable, we must check the significant F stat from the anova table( see attachment)
From the table at attachment we can deduce; as the significant F is less 0.01 , we can safely conclude that the model is signifcant
3) all variables that have a p value less than 0.01 can be safely removed from the model as they do not contribute sigificantly from the model
so education can be removed from the model

Answer:
16
Step-by-step explanation:
Order of operations goes:
1. Solve any problems inside parenthesis or brackets
2. Solve any exponents
3. Solve any multiplication or division from left to right
4. Solve any addition or subtraction from left to right
In this case, we'll need to solve the problem inside of the parenthesis first. Since there are no exponents or multiplication/division problems inside, we'll move on to addition and subtraction from left to right.
4 x (4 - 4 + 4)
4 x (0 + 4)
4 x 4
Now, we multiply
4 x 4
