100 POINTS! ANSWER GIVEN! WORK NEEDED ONLY! SAT MATH A cylinder(not shown) has circular faces with circumferences of 8pi. The height of the cylinder is equal to the radius of its circular faces. What is the volume of the cylinder? Answer: 64pi Please show all the work
Answer:
Vol = 64π
Explanation:
will make it simple and short.
given
circumference of a circle = 2πr = 8π
2πr = 8π
r = 4
h = r = 4
required : Vol
Vol = πr²h
Vol = π 4² * 4
Vol = 64π
Answer:
64 pi
Explanation:
The circumference is given by
C = 2 pi r
8pi = 2 pi r
Divide each side by 2 pi
8 pi /2 pi = 2 pi r / 2 pi
4 = r
The radius is 4
The height is equal to the radius
h =4
We want to find the volume
V = pi r^2 h
= pi ( 4)^2 ( 4)
=64 pi
15. For a random sample of n = 64, find the probability of a sample mean being
less than 24.3 when p = 24 and o = 1.25.
Answer:
0.9726
Explanation:
The computation of the probability of a sample mean is shown below:
[tex]P(\bar x < 24.3)[/tex]
To find the probability first we have to determine the z score which is
[tex]z = \frac{\bar x - \mu_{\bar x}}{\sigma_{\bar x}} \\\\ = \frac{\bar x - \mu }{\frac{\sigma}{\sqrt{n} } } \\\\ = \frac{24.3 - 24}{\frac{1.25}{\sqrt{64} } }[/tex]
= 1.92
Now probability is
[tex]P(\bar x < 24.3) \\\\= P(z < 1.92)[/tex]
= 0.9726
Hence, the probability of the sample mean is 0.9726
We simply applied the above formulas to determined the probability of a sample mean and the same is to be considered

Ebooks are a lifesaver for bibliophiles, finally allowing them to enjoy their love of books without crowding every space in their homes. What does the word "bibliophile" mean in this context?
Answer:
Bibliophile = lover of books, someone with a great love of books.
Explanation:
the word bibliophile comes from Greek biblion ‘book’ + philos ‘loving’.
Based on the context of this passage, the best meaning of bibliophiles is people who love and collect books. Therefore option C is the correct resposne.
What are bibliophiles?The love of books is known as bibliophilia or bibliophilism. A person who adores books and reads them frequently is known as a bibliophile or bookworm.
Most bibliophiles own books they adore or hold dear, as well as vintage copies with distinctive bindings, autographed copies, and copies with illustrations. The term "bibliophile" is applicable to describe a small percentage of book collectors.
Contrary to bibliomania, which is a potential symptom of obsessive-compulsive disorder and involves obsessively collecting books to the point where it may harm one's relationships with others or one's health, bibliophilia does not require that an object be a book to be collected or cherished.

The data collection method that would provide an unbiased sample is "asking five random employees from each shift"
An unbiased sample is a sample whereby all the individuals have and equal chance of being picked for the research study.
In this case, asking five random employees from each shift is an unbiased sampling as everyone has an equal chance of being picked.
Option A is incorrect. Emailing a questionnaire to all the employees will be costly and isn't sampling.
Option B is incorrect. Asking all employees who work from 8am - 5pm is bias as others that doesn't work within the time frame aren't taken into consideration.
Option C is incorrect. Posting a request for the survey volunteers that are in the company's breakroom is biased.

Consider a data set of 15 distinct measurements with mean A and median B , if the highest number were increased , what would be the effect on the median and mean?
Answer:
Mean would increase, median will stay the same.
Explanation:
If the highest numbers were to be increased, than the mean (average), would also increase, because you will be dividing a larger number into 15 parts.
However the median (middle number in a data set), will stay the same because if only the top few numbers get their value increased the middle value will still be the same.

A city of Punjab has a 15 percent chance of wet weather on any given day. What is the probability that it will take a week for it three wet weather on 3 separate days? Also find its Standard Deviation
Answer:
The probability that it will take a week for it three wet weather on 3 separate days is 0.06166 and its standard deviation is 0.9447
Explanation:
Probability of wet weather = 0.15
Probability of not being a wet weather = 1-0.15
We are supposed to find probability that it will take a week for it three wet weather on 3 separate days
Total number of days in a week = 7
We will use binomial over here
n = 7
p =probability of failure = 0.15
q = probability of success=1-0.15
r=3
Formula :[tex]P(r=3)=^nC_r p^r q ^{n-r}[/tex]
[tex]P(r=3)=^{7}C_{3} (0.15)^3 (1-0.15)^{7-3}\\P(r=3)=\frac{7!}{3!(7-3)!} (0.15)^3 (1-0.15)^{7-3}\\P(r=3)=0.06166[/tex]
Standard deviation =[tex]\sqrt{n \times p \times q}[/tex]
Standard deviation =[tex]\sqrt{7 \times 0.15 \times (1-0.15)}[/tex]
Standard deviation =0.9447
Hence The probability that it will take a week for it three wet weather on 3 separate days is 0.06166 and its standard deviation is 0.9447

why and how do humans exist when (eventually) we're all just gonna die, either by mass extinction or we just... die out?
Answer:
The short answer is yes. The fossil record shows everything goes extinct, eventually. Almost all species that ever lived, over 99.9%, are extinct.
Humans have vulnerabilities. Large, warm-blooded animals like us don’t handle ecological disruptions well. Small, cold-blooded turtles and snakes can last months without food, so they survived. Big animals with fast metabolisms – tyrannosaurs, or humans – require lots of food, constantly.
So we’re vulnerable, but there are reasons to think humans are resistant to extinction, maybe uniquely so. We’re a deeply strange species – widespread, abundant, supremely adoptable – which all suggest we’ll stick around for a while
A city of Punjab has a 15 percent chance of wet weather on any given day. What is the probability that it will take a week for it three wet weather on 3 separate days? Also find its Standard Deviation
Answer:
0.06166
sd = 0.9447
Explanation:
probability of having a wet day on any given day at 15 percent = 0.15 is as follows
Lets define X as the number of days that it is going to rain.
we have x binomial (7, 0.15)
probability(x = 3) = (7 3)p³(1-p)⁴
we have 7!/3!4!(0.15)³(0.85)⁴
= (210/6)*0.003375*0.522
= 35*0.003375*0.522
= 0.06166 approximately 0.0617
b standard deviation = [tex]\sqrt{np(1-p)}[/tex]
= [tex]\sqrt{7*0.15(0.85)}[/tex]
= [tex]\sqrt{0.8925}[/tex]
= [tex]0.9447[/tex]
B(n)=2^n A binary code word of length n is a string of 0's and 1's with n digits. For example, 1001 is a binary code word of length 4. The number of binary code words, B(n), of length n, is shown above. If the length is increased from n to n+1, how many more binary code words will there be? The answer is 2^n, but I don't get how they got that answer. I would think 2^n+1 minus 2^n would be 2. Please help me! Thank you!
Answer:
The additional words is [tex]2^n[/tex]
Explanation:
Given
[tex]B(n) = 2^n[/tex]
Required
Determine the additional words; i.e. [tex]B(n + 1) - B(n)[/tex]
From the given parameters, we have that;
B is a function of n
Such that;
[tex]B(n) = 2^n[/tex]
To calculate [tex]B(n+1)[/tex], we simply substitute n + 1 for n
[tex]B(n) = 2^n[/tex]
[tex]B(n + 1) = 2^{n + 1}[/tex]
Applying laws of indices
[tex]B(n + 1) = 2^{n} * 2^1[/tex]
[tex]B(n + 1) = 2^{n} * 2[/tex]
[tex]B(n + 1) = 2(2^{n})[/tex]
Calculating Additional Binary Code;
[tex]B(n + 1) - B(n)[/tex]
Substitute values for B(n + 1) and B(n)
[tex]B(n + 1) - B(n) = 2(2^n) - 2^n[/tex]
Express [tex]2^n[/tex] as [tex]2^ n * 1[/tex]
[tex]B(n + 1) - B(n) = 2(2^n) - 2^n * 1[/tex]
Express 1 as [tex]2^0[/tex]
[tex]B(n + 1) - B(n) = 2(2^n) - 2^n * 2^0[/tex]
Factorize
[tex]B(n + 1) - B(n) = 2^n(2 - 2^0)[/tex]
[tex]B(n + 1) - B(n) = 2^n(2 - 1)[/tex]
[tex]B(n + 1) - B(n) = 2^n(1)[/tex]
[tex]B(n + 1) - B(n) = 2^n[/tex]
Hence, the additional words is [tex]2^n[/tex]
Briefly explain how do z scores lay the foundation for finding out area under normal curve? Write in your own words
Answer:
To find a specific area under a normal curve, find the z-score of the data value and use a Z-Score Table to find the area. A Z-Score Table, is a table that shows the percentage of values (or area percentage) to the left of a given z-score on a standard normal distribution. You need both tables!
