Answer: C "it will be harmful if it takes over the environment."
Explanation: A. if it spreads disease then other animals with it will be harmed B. it will be helpful if it helped try to seed disperse D. if it overpopulates that would harm the environment. so C. has more meaning to it.

Explanation:
using the metric system you would measure the distance from city to city in__________?
Answer:
Kilometers
Explanation:
Kilometers is apart of the metric system which is used almost everywhere in the world aside from the United States. Sometimes the metric system is also known as the "International System of Units" or "SI".
2. Suppose that all possible n = 50 samples are selected from a population. How would the mean,
standard deviation, and shape of the resulting sampling distribution compare to a sampling
distribution based on all possible n= 100 samples?
Using the Central Limit Theorem, it is found that the mean and the shape would remain the same, while the standard deviation would be multiplied by the square root of 2.
Central Limit TheoremThe Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the sampling distribution is also approximately normal, as long as n is at least 30.
In this problem:
The sample size would remain above 30, hence the shape would still be normal.The mean does not depend on the sample size, hence it would remain constant.The standard deviation is inversely proportional to the square root of the sample size, then since the sample size would be divided by 2, the standard deviation would be multiplied by the square root of 2.More can be learned about the Central Limit Theorem at https://brainly.com/question/24663213
Write the equation of a sine or cosine function to describe the graph.
Answer:
y = -3 + 3sin(2t)
Explanation:
Amplitude = 3
period = 5π/4 - π/4 = π
shift down 3
y = -3 + 3sin(2t)
Answer(s):
[tex]\displaystyle y = 3cos\:(2x - \frac{\pi}{2}) - 3 \\ y = 3sin\:2x - 3[/tex]
Step-by-step explanation:
[tex]\displaystyle y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow -3 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{\frac{\pi}{4}} \hookrightarrow \frac{\frac{\pi}{2}}{2} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{\pi} \hookrightarrow \frac{2}{2}\pi \\ Amplitude \hookrightarrow 3[/tex]
OR
[tex]\displaystyle y = Asin(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow -3 \\ Horisontal\:[Phase]\:Shift \hookrightarrow 0 \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{\pi} \hookrightarrow \frac{2}{2}\pi \\ Amplitude \hookrightarrow 3[/tex]
You will need the above information to help you interpret the graph. First off, keep in mind that although this looks EXACTLY like the sine graph, if you plan on writing your equation as a function of cosine, then there WILL be a horisontal shift, meaning that a C-term will be involved. As you can see, the photograph on the right displays the trigonometric graph of [tex]\displaystyle y = 3cos\:2x - 3,[/tex] in which you need to replase "sine" with "cosine", then figure out the appropriate C-term that will make the graph horisontally shift and map onto the sine graph [photograph on the left], accourding to the horisontal shift formula above. Also keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must be careful with your calculations. So, between the two photographs, we can tell that the cosine graph [photograph on the right] is shifted [tex]\displaystyle \frac{\pi}{4}\:unit[/tex]to the left, which means that in order to match the sine graph [photograph on the left], we need to shift the graph FORWARD [tex]\displaystyle \frac{\pi}{4}\:unit,[/tex]which means the C-term will be positive, and by perfourming your calculations, you will arrive at [tex]\displaystyle \boxed{\frac{\pi}{4}} = \frac{\frac{\pi}{2}}{2}.[/tex]So, the cosine graph of the sine graph, accourding to the horisontal shift, is [tex]\displaystyle y = 3cos\:(2x - \frac{\pi}{2}) - 3.[/tex]Now, with all that being said, in this case, sinse you ONLY have a graph to wourk with, you MUST figure the period out by using wavelengths. So, looking at where the graph hits [tex]\displaystyle [\frac{3}{4}\pi, -6],[/tex]from there to [tex]\displaystyle [-\frac{\pi}{4}, -6],[/tex]they are obviously [tex]\displaystyle \pi\:units[/tex]apart, telling you that the period of the graph is [tex]\displaystyle \pi.[/tex]Now, the amplitude is obvious to figure out because it is the A-term, but of cource, if you want to be certain it is the amplitude, look at the graph to see how low and high each crest extends beyond the midline. The midline is the centre of your graph, also known as the vertical shift, which in this case the centre is at [tex]\displaystyle y = -3,[/tex]in which each crest is extended three units beyond the midline, hence, your amplitude. So, no matter how far the graph shifts vertically, the midline will ALWAYS follow.

OPTION
From the given options, three are similar to each other because they follow the
same pattern. Identify the option that is dissimilar to the other three.
DEK
PRW
EGL
TVZ
Answer:
1 is dissimilar
Explanation:
DEK is the option that is dissimilar to the other three. As three are similar to each other because they follow the same pattern. Hence, option A is correct.
What is meant by same pattern?Comparable goods or objects have traits in common when they are two different things. Exemplar: a pattern or model recommended for imitation.
Something made or used as a model for creation is called a dressmaker's pattern. Examples of designs or forms that are artistic, musical, literary, or mechanical are a geometric pattern in a carpet or a strict pattern of rhyme and rhythm in a sonnet.
In order to generate a duplicate, a design, or an expected behaviour, someone or something is used as a pattern. A pattern, or dress pattern, is a set of paper pieces that a seamstress uses to construct a dress.
Thus, option A is correct.

which statement is reasonable? is it the tree is 1 centimeter tall or the tree is 3 meters tall or the tree is 300 meters tall or the tree is 30 kilometers tall?
Answer:
The tree is 300 meters tall.
Explanation:
It depends on the type of tree, as well as how old the tree is, but trees generally grow extremely tall within the right circumstances, such as having enough sunlight, rich soil, and adequate water.
An example of a tree that can grow up to 300 meters is the Coast Redwood.
what unit of measurement is closest to the meter in length? is it
miles or feet or inches or yards?
Answer:
yards
Explanation:
1) There are about 0.000621 miles in 1 meter. The number of miles is clearly way smaller than 1, so miles is not the closet
.
2) There are about 3.28 feet in 1 meter. Again, this shows that 1 foot is not close to 1 meter, so feet is not the closet.
3) There are about 39.37 inches in 1 meter. Clearly, 1 inch is not close to 1 meter.
4)There are about 1.09 yards in 1 meter. 1.09 can round down to 1, so this is the closest to a meter.
