How much does it cost? there is no cost specified
X= -4
Y= 8
I would do an explanation but there’s too many parts and it’s very long and most likely complicated to understand also, but yeah
Answer:
35 minutes
Step-by-step explanation:
Beth left for the airport 105 before her flight was scheduled to leave, and she arrived at the airport 70 minutes before her flight was scheduled to leave.
The difference between when she left and when she arrived will be how long her drive was.
Subtract how many minutes early she was before when she arrived, from how many minutes early she was when she left.
left-arrived
She left with 105 minutes to spare, and 70 minutes left when she arrived.
105-70
35
The drive to the airport took 35 minutes
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
