<u>Given</u>:
The number of tickets sold to children 
The number of tickets sold to adults 
The number of tickets sold to seniors 
To determine the percentage of tickets sold to seniors we need to determine the total number of tickets sold to each category.
<u>To determine the percentage of tickets sold to seniors:</u>
In order to determine the percentage of tickets sold to the seniors, we divide the tickets sold to seniors by the total number of tickets sold to children, adults, and seniors.
This value is multiplied with 100 to convert it into a percentage.
The number of tickets sold to seniors 
The total number of tickets sold to children, adults, and seniors 
The percentage of tickets sold to seniors 
Rounding this off, we get the value as 13.9%
Hence, option 1 is the correct answer.
Set f(b) = b^2 - 75 = to 0 and solve for b:
b^2 = 75
b^2 = 25(3)
b = plus or minus sqrt(25[3]) = plus or minus sqrt(25)*sqrt(3) = plus or minus 5 sqrt(3).

The total number of items sold by each student who participated in a fund-raiser is shown in the stem and leaf plot.
Which statement is best supported by the data in the stem and leaf plot?
The number of students who sold between 10 and 20 items is greater than the number of students who sold more then 40 items.
The number of students who sold more than 30 items is greater than the number of students who sold fewer than 30 items.
The most common number of items sold is 30.
The most common number of items sold is 15.
K=4
add seven on both sides
2x-4y=7
add 4y on both sides
2x=7+4y
divide 2 on both sides
x=7+4y/2
plug that into original equation
2(7+4y/2)-4y-7=0
7 and 4y cancel out
2(2)=0
4=0
Answer:
a) 0.1535
b) 0.4866
c) 0.8111
Step-by-step explanation:

a) the probability that a call in comes within 1/2 minutes is 
=0.1535
b) the probability that a call in comes within 2 minutes is 
=0.4866
c) the probability that a call in comes within 5 minutes is 
=0.8111
