Answer:
D. 81/m^7
Step-by-step explanation:
The applicable rules of exponents are ...
(ab)^c = (a^c)(b^c)
(a^b)^c = a^(bc)
(a^b)(a^c) = a^(b+c)
a^-b = 1/a^b
__
Using these, your expression simplifies to ...

Answer:
D. No, because
and the
are not equal.
Step-by-step explanation:
Given:
Probability of doing yard work is, 
Probability of raining, 
Probability of doing yard work and it raining is, 
Now, two events A and B are independent if,

Conditional probability of event A given that B has occurred is given as:

So, 
Since,
, A and B are not independent events.
Hi there! The answer is C.
The area of the square in the middle is the following:

Hence, the area of the square is 25 cm^2.
The area of one triangle is the following:

Hence, the total area of the four triangles is 4 × 20 = 80 cm^2.
Therefore, the total area of the pyramid is 80 + 25 = 105 cm^2. The answer is C.
