The estimated regression equation by least squares method minimizes the sum of the Group of answer choices Absolute deviations b
ICE Princess25 [194]

Answer:

Squared differences between actual and predicted y

Step-by-step explanation:

The least squares regression method used in predictive modeling for linear regression models produces a best fit line which will minimize the square of the mean difference between the actual and projected or predicted values of the dependent, y variable. Hence, the when the sum of the squared value of the difference between the actual and predicted values (residual) are taken, the fit which gives the minimum sum of squared value is the best fit line upon which the estimated regression equation is based.

At the movie theatre, child admission is $5.40 and adult admission is $8.70 . on friday, 159 tickets were sold for a total sales
blondinia [14]
Alright this is gonna be a long one

Lets called child tickets x and adult tickets y 

so x + y should be equal to 159 since they said that the total sum of the tickets is 159 
so thats your first equation : x + y = 159

next form an equation using the prices, 
5.40x + 8.70y = 1079.70

now that you have your two equations, just substitute the first into the second (you could either substitute for x or y by saying x = 159-y or that y=159-x)

Hope this helps.

8 out of 10 dentists prefer Crest toothpaste what is the ratio of dentist who dont prefer crest toothpaste than those who do?
Nata [24]

Answer:

1:4

Step-by-step explanation:

If 8/10 prefer Crest, that means 2/10 don't prefer it.

To find the ratio, put together the number that don't prefer it to the number that does:

2:8

Simplify by dividing each side by 2:

1:4

So, the ratio is 1:4
