Wade needs to solve the problem 1 5/8 x - 2 1/2 = -11 4/5. He is not sure what to do first, so he rounds the numbers to take a l
ook at a simpler problem. The equation he writes is 2x - 3 = -12.
From this, he can see that he should start solving the original equation by _____.
adding 11 4/5 to both sides of the equation
subtracting 2 1/2 from both sides of the equation
adding 2 1/2 to both sides of the equation
dividing both sides of the equation by 1 5/8
From this, he can see that he should start solving the original equation by _____.
adding 11 4/5 to both sides of the equation
subtracting 2 1/2 from both sides of the equation
adding 2 1/2 to both sides of the equation
dividing both sides of the equation by 1 5/8

The computer regression output includes the R-squared values, and adjusted R-squared values as well as other important values
a) The equation of the least-squares regression line is
b) The correlation coefficient for the sample is approximately 0.351
c) The slope gives the increase in the attendance per increase in wins
Reasons:
a) From the computer regression output, we have;
The y-intercept and the slope are given in the <em>Coef</em> column
The y-intercept = 10835
The slope = 235
The equation of the least-squares regression line is therefore
b) The square of the correlation coefficient, is given in the table as R-sq = 12.29% = 0.1229
Therefore, the correlation coefficient, r = √(0.1229) ≈ 0.351
The correlation coefficient for the sample, r ≈ <u>0.351</u>
c) The slope of the least squares regression line indicates that as the number of attending increases by 235 for each increase in wins
