Answer:
A. 10m - 16
Step-by-step explanation:
First, distribute 3 to all terms within the corresponding parenthesis, and -2 likewise:
3(4m - 2) =
3 * 4m = 12m
3 * -2 = -6
3(4m - 2) = 12m - 6
-2(m + 5) =
-2 * m = -2m
-2 * 5 = -10
-2(m + 5) = -2m -10
Combine like terms:
12m - 6 -2m - 10
12m - 2m - 6 - 10
(12m - 2m) + (-6 - 10)
10m - 16
A. 10m - 16 is your answer.
~
Answer:
10 m - 16 (Answer A)
Step-by-step explanation:
We use distributive property to eliminate parenthesis:
12 m - 6 - 2 m -10
and now combine like terms:
[12 m - 2 m] - 6 - 10
10 m - 16
Therefore, answer option A. is the correct one

A restaurant manager uses the expression 7.85m + 8.85d to calculate his profit when he sells m main courses and d desserts. What is the restaurant manager's profit, in dollars, when he sells 45 main courses and 43 desserts?
Answer:
244 and 43
Step-by-step explanation:
hope this helps n please mark brainliest
Answer:
$733.80
Step-by-step explanation:
To calculate the profit, you use 7.85m + 8.85d
Since m = 45 and d = 43,
his profit = (7.85 × 45) + (8.85 × 43)
= 353.25 + 380.55
= 733.80
∴The restaurant manager's profit in dollars is $733.80.

Find the area of the complex figure.
A figure has 8 sides; all sides meet at right angles. The left-most vertical side measures 31 meters. The lower most horizontal side measures 69 meters. The right-most vertical side measures 31 meters. The upper right horizontal side measures 23 meters. The middle horizontal side measures 23 meters. The upper middle left vertical side measures 12 meters.
Answer:
The answer would be 2691 meters.
Step-by-step explanation:
When looking at the figure, since you know the length of all of the sides you can easily cut it into three simpler rectangles by extending the line of 23 meters out to either side.
This gives us three rectangles by the measures of 23 by 12, 23 by 12, and 31 by 69.
In order to calculate area you do equation A=LxW
In this case, Area=(23) x (12)
This will get you the answer 276 meters.
Do this again for the other rectangle that measures 23 by 12, and add the two areas together.
This gives you 552 meters.
To find the area of the remaining triangle, once again do A=LxW
Area=(31) x (69)
This will give you 2139 meters.
To find the total area of the figure, add the two areas that we have already found out together,
522+2139
and you get your answer of 2691 meters.

What is the best way of choosing a sample to statistically represent a population? Why? What is a biased sample? How can biased sampling affect the statistical study of a population?
Search the Internet and give two or more real-world examples of biased sampling leading to unexpected or unfavorable outcomes. In each case, how could the sample have been improved to make a more accurate inference about the population?
Answer: In random sampling, the whole population should have an equal chance of being chosen.
Step-by-step explanation:
In a simple random sample, every member of the population has an equal chance of being selected.
Your sampling frame should include the whole population. To conduct this type of sampling, you can use tools like random number generators or other techniques that are based entirely on chance.
Biased sample
A sample is biased if individuals or groups from the population are not represented in the sample.
In statistics, sampling bias is a bias in which a sample is collected in such a way that some members of the intended population have a lower or higher sampling probability than others.
Affects
It affects the internal validity of an analysis by leading to inaccurate estimation of relationships between variables. It also can affect the external validity of an analysis because the results from a biased sample may not generalize to the population.
Sampling is one of the procedure to get information about population. The best way to choose a sample representing a population is simple random sampling.
Why do we do sampling?We do sampling so that we don't have to work on entire population of items but only on that sample in a way that we can predict information about population.
Most of the times, it isn't possible in real world to work on entire populations. Samples come out for rescue by assumptions that they will have some properties of the population pertained in them.
Thus, the sample should be taken out such that it includes data of the population as much as it can in unbiased way so as to imitate population. (assuming that we want the sample to contain the summary of the population).
What is simple random sampling?If the sampling is done from the population randomly, without any other rule, then such sampling is called simple random sampling. Items are selected in a fixed size, all randomly.
What is stratified sampling?Sampling which is done by taking the main population divided in categories(called strata), then such sampling from stratas (sub-parts of the population) is called stratified sampling.
What is systematic random sampling?In this type of sampling, starting of the sampling is done randomly, but then rest of the samples are collected by an order. Like for example, first point is selected randomly, then all points are selected that they are equidistant from each other in the population.
What is convenience sampling?The word "convenience" summarizes this sampling. It is done in a way that those values from population are sampled which are in convenience with the researcher. Like if some random picking is to be done from beads spread on the ground, then the researcher picking those beads which are closer to him.
Convenience sampling and stratified sampling are biased, as convenience sampling is leaving a good amount of population untouched, and stratified sampling is taking about sub-parts of the population.
The systematic random sampling is not good in those cases where population doesn't contain variation equally, and we might end up doing systematic sampling in that region which is biased than other regions.
The best sampling is simple random sampling, as it is randomly picking data values from the population, so is most probable to get the properties of the population(the more you're lost, the more probable you're to get to new paths). If sample size is large enough, this sampling comes out as best sampling method, in context of summarizing the information of the population, as almost all of the properties of the population is covered by values obtained during simple random sampling.
Thus, the best way to choose a sample representing a population is simple random sampling. (assuming that we want to summarize the population).
