Answer:

Option D:The statement does not make sense. A sample is a subset of the population and cannot be larger than the population.

Step-by-step explanation:

The statement does not make sense. A sample is a subset of the population and cannot be larger than the population.

We measure characteristics of a sample to infere properties of the population. In real cases, the samples are much smaller than the population.

The sample size is calculated in order to achieve the desired level of confidence in the estimation. This confidence usually increases by the root of the sample size.

What is the product of (2p+7)(3p+4p-3)
Alex

Answer:

The answer is C=6p3 + 29p2 + 22p – 21

Step-by-step explanation:

To calculate the product, we need to multiply each member of each multiplier:

(2p + 7)(3p2 + 4p – 3) = 2p · 3p² + 2p · 4p + 2p · -3 + 7 ·3p² + 7 · 4p + 7 · -3

                                   =    6p³     +     8p²    -     6p    + 21p²   +  28p   -     21

                                   = 6p³ + 8p² + 21p² + 28p - 6p -21

                                   = 6p³ + 29p² + 22p - 21

Therefore, the product of (2p + 7)(3p2 + 4p – 3) is 6p³ + 29p² + 22p -21
