Answer: 8
Step-by-step explanation: That digit above the 2 is a exponent. It represents the number of times 2 is multiplying itself. This is simply 2x2x2. 2x2x2=4x2=8
Answer: 1/b6
Step-by-step explanation:
Answer:
True
Step-by-step explanation:
Point estimation of a population parameter provides an estimate of a single value calculated from the sample that is likely to be close to its value to the unknown parameter. Itis to be noted that a point estimate will not in general be equal to the population parameter as the random sample used is one of the many possible samples which could be chosen from the population.
For example, in estimation, we may estimate the mean and the variance of a population by computing the mean and the variance of the sample drawn from a population.
The only thing you can do here is to try to simplify, so I'll assume that's what you want to do.
The numerator is a difference of squares, so it's easy to factorize:
In the denominator, we factorize by grouping:
So we have
