3 0
Y = x² - 11x + 24
0 = x² - 11x + 24
x = <u>-(-11) +/- √((-11) - 4(1)(24))</u>
                       2(1)
x = <u>11 +/- √(121 - 96)</u>
                    2
x = <u>11 +/- √(25)
</u>              2
x = <u>11 +/- 5</u>
            2
x = <u>11 + 5</u>      x = <u>11 - 5</u>
           2                   2
x = <u>16</u>            x = <u>6</u>
       2                   2
x = 8              x = 3

The x - intercept of the equation is equal to {8, 3}.

You have all five questions correct. Nice work

-------------------------------

Problem 1: There are 8 spaces labeled 1 though 8 so the proper sample space is {1,2,3,4,5,6,7,8} which is basically all the possible outcomes

Problem 2: There is one "3" out of 8 total, so 1/8 is the probability of landing on 3

Problem 3: There are 4 spaces that are even {2,4,6,8} out of 8 total {1,2,3,4,5,6,7,8}. So 4/8 = 1/2

Problem 4: There are 4 blue out of 3+5+4 = 12 total, so 4/12 = 1/3

Problem 5: We got 24 red out of 40 total, so 24/40 = 3/5
