You can put this solution on YOUR website! identify the amount,base,and p value of 25% of 400cars is 100 cars

18% of 500 = 90 people
-------------------
Yellowstone National Park has 3366mi.2 of undevelopedland. If this represents 99% of the total area, ,find the total area of the park?
---
0.99*(total area) = 3366 sq mi
total area = 3366/0.99 = 3400 sq. mi.
--------------------------------
As of the 2002--2003 football season, Peyton Manning had completed 1357 passes out of 2226 attempts. Find his completion percentage to the nearest tenth of a percent.
1357/2226 = 0.60961 = 61%
