I think your answer would be D-12
The probability of choosing one of us is 2 / 80 .
If that happens, then the probability of choosing
the other one is 1 / 79 .
The probability of both things happening is
(2/80) x (1/79) = 1/3160 = 0.0003165... = 0.032... percent
1) 7^3 x 7^4 = 7^(3+4) = 7^7
2) (-6)^12 x (-6)^5 x (-6)^2 = (-6)^(12+5+2) = (-6)^19
3) 2^2 x 2^7 x 2^ 0 = 2^(2+7+0) = 2^9
Answer:
What prisms
Step-by-step explanation:
In order for the whole expression to be negative, either (x⁵)
or (y⁴) or (z²) must be negative.
But an even-numbered power can't be negative ... even if the base
is a negative number, any even-numbered power of it is positive.
So (y⁴) and (z²) are always positive. The expression can be
negative if 'x' is negative, because (x⁵) will then be negative.
None of the proposed requirements is appropriate, so the
final answer is E. None .
