Well, is just their difference, let's first convert the mixed fraction to "improper" and then subtract.

\bf \stackrel{mixed}{1\frac{1}{8}}\implies \cfrac{1\cdot 8+1}{8}\implies \stackrel{improper}{\cfrac{9}{8}}\\\\
-------------------------------\\\\
\cfrac{9}{8}-\cfrac{3}{4}\impliedby \textit{our LCD is then 8}\implies \cfrac{(1\cdot 9)~~-~~(2\cdot 3)}{8}
\\\\\\
\cfrac{9-6}{8}\implies \cfrac{3}{8}

predict the attendance for minor league baseball in the year 2005. a. 5,208,000 b. 4,495,000 c. 44,950,000 d. 52,080,000
solong [7]

Answer:

c. 44,950,000

Step-by-step explanation:

The following table is missing:

Year   Attendance (millions)  

1985   18.4  

1990   25.2  

1995   33.1  

2000  37.6  

Using a calculator, the line of best fit is obtained. Equation:

y = 1.31x - 2581.6

where y is attendance (in millions)  and <em>x</em> is the year. Replacing with x = 2005 into the equation, we get:

y = 1.31(2005) - 2581.6

y = 44.95 millions or 44,950,000
