The school carnival committee sold a total of 200 tickets for the grand prize drawing. Sue bought enough tickets so that she had a 20 percent chance of winning the grand prize. How many tickets did Sue buy?

40 tickets

Step-by-step explanation:

Given that:

Total tickets sold = 200

Sue's chances of winning = 20% = 0.2

Number of tickets bought by Sue :

P(winning) = 20%

P(winning) = required outcome / Total possible outcomes

Required outcome = number of tickets bought by Sue

Total possible outcomes = total number of tickets sold

0.2 = x / 200

x = 0.2 * 200

x = 40

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
