The average attendance at a local high school's football games went down from 1800 people in 2003 to 500 people in 2004. What was the percent decrease in attendance at the football games?

Step-by-step explanation:

%decrease = 1800 - 500 * 100

1800

%decrease = 1300/1800 * 100

% decrease = 72.2%

Average attendance in 2003 = 1800

Average attendance in 2004 = 500

Decrease in attendance = 1800 - 500 = 1300

Decrease percentage in attendance

=72.22

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
