Answer:
As the sample size increases, the variability decreases.
Step-by-step explanation:
Variability is the measure of actual entries from mean. The less the deviations the less would be the variance.
For a sample of size n, we have by central limit theorem the mean of sample follows a normal distribution for random samples of large size.
X bar will have std deviation as 
where s is the square root of variance of sample
Thus we find the variability denoted by std deviation is inversely proportion of square root of sample size.
Hence as sample size increases, std error decreases.
As the sample size increases, the variability decreases.
Answer:
x = 100√3
Step-by-step explanation:
tan(30º) = x/300
x = 300 tan(30º)
x = 300/√3
x = 100√3
Answer:
Something like M=80-(7x4)
Step-by-step explanation:
Answer: There are several ways in which we can determine our marketing budget. Some of these are given below:
<u><em>1. Percentage of revenues:</em></u>
Under this method we usually take a fixed percentage of our revenues and further allocating this amount for marketing. We will choose the percentage that works best for us.
<u><em>2. Percentage of net sales:</em></u>
This method determines our marketing budget as a fraction of our net sales. This method will take a lot of trial and error to find the percentage that works well for our company.
<u><em>3. Industry specific:</em></u>
Nowadays, industries have specific projections as to the amount they will need to spend on marketing . The best way to get these numbers is to find a firm that represents our industry and ask them to provide us with averages. We can then refine the actual costs.
<em><u>4. Objective/task oriented
</u></em>
This is model that works by setting out goals, planning out the tasks and then estimating the cost for all of these tasks. It works greatly for firms who have a immense knowledge about measurements and information of their business processes.
Multiplicative inverse is a number which when multiplied with the current number, the answer unit (that is, 1).
Now,
1.725 = 1725/1000 = 69/40
Inverting this and multiplying it with the results yields 1. That is,
69/40*40/69 = 1
Therefore, the multiplicative inverse of 1.725 is 40/69
