We know that P(D\cap E)=P(D)P(E)=\boxed{0.1134}.

And P(D\cup E)=P(D)+P(E)-P(D\cap E)=\boxed{0.5766}.

Hope this helps.

Simplify p^-8/7^-2q^-9
ExtremeBDS [4]

Answer:

\frac{7^2}{p^8 \cdot q^9}

Step-by-step explanation:

\frac{p^{-8}}{7^{-2}} \cdot q^{-9} = \frac{\frac{1}{p^8}}{\frac{1}{7^2}} \cdot \frac{1}{q^9} = \frac{7^2}{p^8 \cdot q^9} by the definition of negative exponents: a^{-b} = \frac{1}{a^b} for all a,b so long as a\ne 0.

This question difficult and i need some help would anyone please help me
wel

Answer:

x = 30

F = 130

G =  50

Step-by-step explanation:

f and g are supplementary which means they add to 180

5x-20 + 3x - 40 = 180

Combine like terms

8x - 60 = 180

Add 60 to each side

8x-60+60 = 180+60

8x = 240

Divide by 8

8x/8 = 240/8

x = 30

F = 5x -20 = 5*30 -20 = 150 -20 = 130

G = 3x-40 = 3*30 -40 = 90-40 = 50
