the square of a negative number always be positive
eg: -2² = -2×-2 = (-×- = +) +4
the cube of a negative number always be positive
eg: -2³ = -2×-2×-2 = (-×-×- = +) -8
hope it helps...!!!
Answer:
the probability is equal to 0.0123
Step-by-step explanation:
given,
Probability of hitting a Target by A (p)= 1/3
Probability of not hitting a Target by A (q) = 1 - 1/3
= 2/3
given, problem follows negative binomial distribution
let X be the probability of hitting the target for first time in third throw
X follow NBin. (k = 3 , p = 1/3)
=
=
= 0.0123
hence, the probability is equal to 0.0123
Answer:
All the edges of a cube have the same length, and the volume of a cube is the length of an edge taken to the third power. So the length of the edge of a cube with a volume of 125 is 5.
