White figure Area = 128
White surface area = appro. 301
Yellow area = 320
Yellow Surface area = approx. 653
Area found with = 2πrh+2πr2
Surface Area found with = 2πrh+2πr2
You need to memorize them for tests
Hope that helped!!! k
Answer:
The time it will take the population to grow to 800 insects is 17 days.
Step-by-step explanation:
The growth function of the insects is exponential.
The exponential growth function is:

Here,
<em>y</em> = final value
<em>a</em> = initial value
<em>r</em> = growth rate
<em>t</em> = time taken
It is provided that there were 270 insects after 9 days and initially there were 80 insects.
Compute the value of <em>r</em> as follows:

Now, compute the time it will take the population to grow to 800 insects as follows:

Thus, the time it will take the population to grow to 800 insects is 17 days.

Answer:
The correct option is D. No, because a random sample from all customers of the shopping mall was not selected
Step-by-step explanation:
In statistics, Bias can be described as a term which depicts error if a sample is not taken evenly or it depicts errors taken from an unjust sampling.
In statistics, sampling bias means the errors which occur if one part of the population is favoured more then the rest of the populations. In this kind of bias, the individuals for experimentation are not chosen randomly.
As the customer satisfaction survey was distributed in only one of the gates hence, it does not give a generalized result and the result is biased.
