Answer:
When sampling from a population, the sample mean will: be closer to the population mean as the sample size increases.
Step-by-step explanation:
The sample mean is not always equal to the population mean but if we increase the number of samples then the mean of the sample would become more and more closer to the population mean.
Usually the population size is very huge that is why we select a random sample from the population, care must be taken to ensure randomized sampling otherwise results would not be accurate. After that we have to make sure that the number of samples are enough for the given population size. The number of samples depends upon the shape of the population. If the population is normal than according to central limit theorem, a less number of samples would be enough to ensure normal distribution of sampling mean, otherwise a greater sample size will be required.
15-27b+11=-244
26-27b=-244
-27b=-270
b=10
Answer:
Supplier A: 5.25 per bushel and deliver fee of 3 per bushel
Supplier B: 6.50 per busher and flat delivery fee of $1500 each week
500 bushels of grain each week.
Supplier A: 5.25x + 3x = 5.25(500) + 3(500) = 2,625 + 1,500 = 4,125
Supplier B: 6.50x + 1500 = 6.50(500) + 1500 = 3,250 + 1,500 = 4,750
Supplier B would cost more if the company buys 500 bushels of grain per week.

Answer:
Step-by-step explanation:
we know that
In a <u>Geometric Sequence</u> each term is found by multiplying the previous term by a constant, called the common ratio (r)
In this problem we have
Remember that
-----> 
-----> equation A
Substitute the values of a_5 and a_2 and solve for r
Find the value of a_1 in equation A
therefore
The explicit rule for the nth term is
substitute
Answer:
Rectangle
Step-by-step explanation:
If the base is a square that means the cross-section can also be a square.
