Answer:
(-2, -8/3)
Step-by-step explanation:
2(-2) - 6y = 12
-4 -6y = 12
-6y = 16
y = -16/6 = -8/3
Solving process:
1. Plug numbers into formula with their corresponding variable.
V=(1/3)Bh
216=(1/3)(36)h
2. Multiply 1/3 and 36.
216=12h
3. Divide 216 by twelve.
18=h
4. The height is 18 cm.
For 1 play, the chance of gaining $8 is 4/38, while the chance of losing the $1 is 34/38. Therefore, the expected value is ($8)(4/38) + ($-1)(34/38) = $(-1/19). Over 50 plays, which are mutually independent of each other, we multiply the number of plays by the expected value to get $(-50/19) = $-2.63.

-12x² + 11x - 3 = 0
x = <u>-(11) +/- √((11)² - 4(-12)(-3))</u>
2(-12)
x = <u>-11 +/- √(121 - 144)</u>
-24
x = <u>-11 +/- √(-23)
</u> -24
x = <u>-11 +/- i√(23)</u>
-24
x = <u>-11 + i√(23</u>) x = <u>-11 - i√(23)</u>
-24 -24
x = ¹¹/₂₄ - 0.0416√(23) x = ¹¹/₂₄ + 0.0416√(23)
