2 beginner, 6 intermediate, 3 advanced...total of 11
P(advanced) = 3/11
replaced
P(beginner) = 2/11
P(both) = 3/11 * 2/11 = 6/121 <=
8 hundred thousands and 1 thousand.
Answer:
c =
Step-by-step explanation:
Given
R=
Clear the radical by squaring both sides
R² = b² - 4ac ( subtract b² from both sides )
R² - b² = - 4ac ( multiply all terms by - 1 )
b² - R² = 4ac ( divide both sides by 4a )
= c
It is "(C) 225pi cm3"
I am 100% sure this is correct.
