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

Answer:

The fastest runner is Katie

Step-by-step explanation:

In order to determine this, we must first put them all in the same terms. For the purpose of this, we will put them all in feet per second.

Katie

14 feet/1 second = 14 ft per second

Zach

576 feet/46 seconds = 12.52 ft per second

Tony

1 mile/533 seconds = 5280 feet/533 seconds = 9.91 ft per second

Will

827 feet/1 minute = 827 feet/60 seconds = 13.78 ft per second.

So we know that the fastest is Katie.
