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:
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]
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.

A health food manufacturer makes two types of protein shakes, Whey and Vegan. Each mixture contains vitamins, protein, and carbohydrates, in the following proportions: Carbohydrates (g) Protein (g) Vitamin (g) Whey 100 400 300 Vegan 200 300 100 Minimum dietary requirements are that a protein shake contain at least 0.9kg of vitamins, 2.2kg of protein, and 0.8kg of carbohydrate. Whey costs N$20 per kilogram to produce, and Vegan costs $12.50 per kilogram to produce. Find the number of kilograms of each protein shake that should be produced to minimize cost

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

in your own words explain what is meant by inclusive education
Inclusive education means all children in the same classrooms, in the same schools. It means real learning opportunities for groups who have traditionally been excluded – not only children with disabilities, but speakers of minority languages too.

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
Which of the following is an example of a parameter? 9047 out of 531,310 citizens voted in the special election for city council. Half of the receipts at the coffee shop include web address for giving feedback. 3.5% of the restaurant goers are given a survey to fill out. All of the members of the community watch group gave their availability to volunteer over the summer.
Answer:
All of the members of the community watch group gave their availability to volunteer over the summer.
Explanation:
In Statistics, a parameter can be defined as a fixed quantity which summarizes the characteristic of an entire population. Generally, a parameter gives a detailed description of a given population.
In this scenario, all of the members of the community watch group making known their availability to volunteer over the summer is an example of a parameter.
Another example of a parameter is, asking all tutors on brainly website what subject they love tutoring most and half of them said Mathematics; 50% of the total tutors loves Mathematics---this is a parameter.
