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.

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]

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]

What is a thesis?The sentence that represents a writing assignment's main claim and helps to organize the thoughts in the document is referred to as the thesis statement. A thesis is an assertion that has been argued, proven, or otherwise supported at the outset of an argumentative document. It typically states a scientific principle, a thesis, or a verifiable fact.
A thesis is the concrete statement of an idea that is disclosed in an open and supported manner. It is derived from the scientific process. It can also be referred to as scientific theory because a theoretical foundation can be regarded as a component of the body of knowledge. In an argumentative text, the writer usually conforms to their viewpoint on the issue they are discussing. Afterward, the author

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
