Is the given question a statistical question? Explain. (NOT A MULTIPLE CHOICE)
a. "What is the tallest building in Chicago, Illinois?"
b. "What is the most popular store in the Turtlecreek Mall among among teenagers?"
Part (a)
Answer: No, it's not a statistical questionWhy not? Because we can locate the tallest building without having to gather a sample and computing any statistical values based on the sample data. Note how we have one single building and we're focused on just that building only. We aren't asking anything about a population of buildings. Statistics is the science of trying to measure a population in some way, often through the use of a sample statistic. For example, if we asked "what is the average building height in Chicago, Illinois?", then we would be asking a statistical question. Ideally, we would measure every single building in the city. Of course, that's very time consuming and impractical. So the next best thing is to randomly select a sample of buildings and try to estimate the average height like that.
Once again, we're only focused on one single building and not several. So we don't do the operations of gathering a sample and we aren't doing any statistics here. We're simply measuring the building, or looking up the building height in some records database.
=============================================================
Part (b)
Answer: Yes, it is a statistical questionThe population is the set of teenagers. This could be narrowed to just the teens in one specific town, county, or regional area. It doesn't make much sense to extend the population out too far because teens too far away would likely not visit this particular mall in question. Let's say the population is every teen in a certain county. We have a lot of people in this population, so we'll have to gather a sample. Doing a census is too time consuming and expensive. This process of gathering a sample points to this question being a statistical one. We don't know which store is the most popular, but we can get a fairly good idea through the sampling process. It won't be a 100% guarantee that we got the right one considering that again the sample isn't the exact population, but we should get close if we did the sampling right.
Note how the variable in question is a qualitative one. The store names are the categories or names that the teens select in the survey. This data type is nominal and not ordinal, since stores do not have an inherent rank (other than alphabetical but that's not of much importance). Also note that the responses for this random variable are, more or less, random in nature. We simply don't know how the teens will respond assuming we go into this completely blind. It's a good idea to do so to avoid bias. This random nature helps add evidence we have a statistical question here. The random variable value is not set in stone like the tallest building is. Keep in mind that the question for part (a) is asked to refer to a very specific narrow window of time. The same can be said for part (b) as well. Be sure to carefully set up the question and avoid any ambiguity.
To summarize, to answer such a question given to us we would need to gather a sample and compute sample statistics. This is why we have a statistical question here.

Find value of x
Find value of y
Answer:
x = 17.32
y = 10
Step-by-step explanation:
USsing the SOH CAH TOA identity
sin theta = opp/hyp
sin 30 = y/20
y = 20sin30
y = 20(0.5)
y = 10
Using Pythagoras theorem to get the value of x
20^2 = x^2 + y^2
400 = x^2 + 10^2
400 - 100 = x^2
300 =x^2
x = √300
x = 17.32
Answer:
x = 17.32 ,y = 10
Step-by-step explanation:
Use ratio of cosine :-
cos 30° = x/20 √3/2 = x/20 x = √3/2 * 20 x = 10√3 x = 10 * 1.732 x = 17.32Use ratio of sine :-
sin 30° = y/20 1/2 = y/20 y = 20 *1/2 y = 10Hellppp please i need help

Decide whether or not it is a function.
Answer:
Step-by-step explanation:
Yes it's a function.
You may be looking at v which produces m
You may be looking at r which also produces m.
That's fine. Two different x values (the domain) can produce the same y value. Lots of functions do that. (you'll study parabolas pretty soon and all that open up or down have two x values producing the same y value).
If you have a member of the domain producing 2 y values, that doesn't work. That would not be a function.
This example is a function.

Olivia spends $4 creating lemonade, and sells the cups for $1 each. Nathan spends $5 creating lemonade and sells the cups for $0.50 eac. How many cups does it take for them to make the same amount of money?
Answer: 2 cups
Step-by-step explanation: Olivia spends 4$ and nothing more. 1$ is her profit that can continue to gain and can be represented as 1x or x. x-4 is the equation to represent her profit. Nathan spends 5$ and 0.50$ is his profit which can be shown as 0.5x. 0.5x-5 is the equation to represent his profit.
Set those two equations equal to each other. [tex]0.5x-5=x-4[/tex]
Isolate x. [tex]0.5x=-1[/tex]
Solve for x. [tex]x=-2[/tex]
Since x represents the amount of cups sold, you cannot have a negative amount of cups sold. Therefore, Olivia and Nathan must sell 2 cups to make the same profit.

A. 90°
B. 57°
C. 180°
D. 123°
Answer:
do you have a picture to help?
The measure of angle 6 in the transversal that cut the parallel lines is 57 degrees
Angles formed when a transversal cut parallel lines
When a transversal line cut parallel lines, the angles formed are corresponding angles, alternate angles, vertically opposite angles etc.
Therefore,
∠2 = 180 - 123 = 57° (angle on a straight line)
Therefore,
∠2 ≅ ∠6 (corresponding angles)
Hence,
∠6 = 57 degrees

A. Jon's house is considered a liability only because he still owes money on it.
B. Jon has an $180,000 asset and a $142,500 liability.
C. Jon has a $142,500 asset and an $180,000 liability.
D. Jon's house is considered an asset only because it is worth more than he owes
Answer:
Question 1. A
Question 2. D
Question 3. B
Step-by-step explanation:
Number 1 is A because, primary beneficiary: The primary beneficiary is the person (or persons) who will receive the proceeds of the life insurance policy when the insured person dies. However, the primary beneficiary will not receive any proceeds if he or she dies before the death of the named insured.
Question 2 is D because, After when someone dies, the beneficiary of the life insurance policy will require to make a death claim to receive the insurance amount.
When you have a term life insurance policy, the value or the death benefit, it will not have any impact on the benefits you receive.
Life insurance is one of the type of insurance, or risk protection, that gives payment to a nominated beneficiary after the policyholder's death.
Term life insurance pays advantages to those who named beneficiaries when the policy holder dies during the time of the policy.
.When a person dies, the insurance company investigates and then claim and then pays out to the death benefit.
Best of luck!!
