Answer:
11 feet.
Step-by-step explanation:
We are told that Tenley is making a square frame for her painting. She is using 4 pieces of wood that are each 2.75 ft long.
To find the total amount of wood used in making the frame we will multiply amount of wood of each piece (2.75) by number of wood piece used to make the frame (4).
Therefore, Tenley used 11 feet of wood to make the frame.
Answer:
see explaination
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
