What is the value of the expression x^3y^2/6 + x^2y^2 x = -2 and y = 3?
Volgvan

\huge\text{Hey there!}

\mathsf{\dfrac{(-2^3)(3^2)}{6}+(-2^2)(3^2)}

\mathsf{(-2)^3=\bf -8}

\mathsf{= \dfrac{-8(3^2)}{6}+(-2^2)(3^2)}

\mathsf{3^2=\bf 9}

\mathsf{= \dfrac{(-8)(9)}{6}+(-2^2)(3^2)}

\mathsf{-8(9)= \bf -72}

\mathsf{= \dfrac{-72}{6}+(-2^2)+(3^2)}

\mathsf{\dfrac{-72}{6}=\bf -12}

\mathsf{= -12+(-2)^2(3^2)}

\mathsf{-2^2=\bf 4}

\mathsf{= -12+4(3^2)}

\mathsf{3^2=\bf 9}

\mathsf{= -12+4(9)}

\mathsf{4(9)= \bf 36}

\mathsf{-12 + 36 = \bf 24}

\boxed{\boxed{\large\text{Answer: \huge\bf Option C. 24}}}\huge\checkmark

two dice are rolled in succession. determine the probability that their sum is 10 or more,given that the first die is a 5
MrRa [10]
If the first die is a 5, the second must be 5 or more in order to have a sum of at least ten.

Assuming it is a six sided die, the two values that would make this true are 5 and 6.

2 values/6 possible would be a probability of 2/6, which simplifies to 1/3

Final answer: 1/3
