Answer:
(A) a=1,b=5,c=9
Step-by-step explanation:
We want to simplify for values of a, b and c which satisfies:
Converting our result to mixed fraction
Answer:
Finding the error for each observation, squaring the error and minimizing the sum
Step-by-step explanation:
The regression line is a straight line which gives a description of how the dependent variable y changes as changes occur in the independent variable X. It gives a prediction of the value of Y for any given value of X.
The method of least squares is used for squaring the error and also used for minimising the sum. Therefore, when you calculate the regression line, you would be Finding the error for each observation, squaring the error and minimizing the sum.
5(3t+2) + 7(2t+5)
because for each of the 3t+2 tickets you make $5 and for each of the 2t+5 tickets you make $7
$2.88/12 = <u><em>$0.24 per ounce of body wash
</em></u><em></em>This can be solved by using a calculator.
Hope this helps!
