Answer:
b. Invalid, because the sample may not be representative of the population.
Step-by-step explanation:
A sample of around 10% of the population is needed to be representative.
In this question:
We have a population of 500,000, and a sample of 10,000.
10,000/500,000 = 1/50 = 0.02 = 2% of the population, so not representative, and option b is correct.
\left[x _{2}\right] = \left[ 6+\sqrt{33}\right][x2]=[6+√33]
Answer:
6(3-2)
Step-by-step explanation:
Find the GCF of both numbers. The GCF is 6. Write it as 6( - )
Then, divide both numbers by 6. 18 divided by 6 is 3 and 12 divided by 6 is 2. Fill in the blanks with 3 and 2. A=6(3-2)
