It means it is asking for a large number so it can represent more of the population because the larger the number the more percent of population so the answer would be A

Answer:

Option A)89

Step-by-step explanation:

The central limit theorem says that the mean of the samples taken would be the variable which has normal distribution in spite of the original distribution which it belonged to.

In other words, if X is a random variable, and various samples of x are taken and their means are arrived.  These means would be normal provided sample sizes are large and sample are drawn unbiased.

The larger the sample size the more closer the sample mean would be to the normal mean.

Out of the 4 options, 1,9 and 19 are too small to consider to be normal also since for normal distribution minimum sample size is 30.

Hence the only correct answer is Option A) 89

Given:

The figure of a triangle DEF.

To find:

The coordinate of image of given triangle after reflection over y-axis.

Solution:

The vertices of given triangle are D(1,4), E(4,3), F(2,0).

If a figure is reflected over the y-axis, then the rule of reflection is

(x,y)\to (-x,y)

Using this rule, we get

D(1,4)\to D'(-1,4)

E(4,3)\to E'(-4,3)

F(2,0)\to F'(-2,0)

Therefore, the coordinates of image are D'(-1,4), E'(-4,3) and F'(-2,0).

Personal Statement
leonid [27]

Well, as it says, your first statement needs to explain what interests you about the program.

If you feel you need multiple paragraphs, let the first be an introduction, around 4 or 5 sentences. Include, possibly what pushed you to apply for this program, what you're looking forward to, and a reason for them to hire you. You can add a thesis statement of sorts if that helps (a short statement, usually one sentence, that summarizes the main point or claim of a paper). The first paragraph can be short, it doesn't need to be too in-depth. You can talk more about that later in your statement.

The body paragraphs must include your goals and extracurricular interests (what courses would you like to take and why?).

As it states, you must list your GPA, what interests you about the Major and/or Minor/Workshop courses, and what you can contribute (you can build off of what you said in your first paragraph here).

It is very important to share additional details you think are important, such as accomplishments you are proud of, for example.

A conclusion would be nice, a short and sweet wrap-up of your overall statement (not too long).

Remember, the name of the game is to sound confident and prove to them that you are in fact a good fit for the program! Good luck! Stay focused ^^
