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
Answer:
3 balls per can
Step-by-step explanation:
It there are 3 cans and 9 balls if you just divide 9 balls by 3 cans you get the answer which is 3 balls per can.

The retrospective or historic cohort story, is a longitudinal cohort story that considers a particular set of individuals that share the same exposure factor to ascertain its influence in the developments of an occurrence, which are compared with the other set or cohort which were not exposed to the same factors.
Retrospective studies have existed about the same time as prospective studies, hence their names.
Answer:
Perimeter is a length of a figure's borders.
Pabc = a+b+c
Area shows the 'size' of the figure.
Sabc = 1/2*a*b*Sin(alpha) or 1/2*a*h or sqrt((half perimeter * a)(half perimeter * b)(half perimeter * c))
