The words to fill each gap, respectively, are Portal of entry, Vector, Reservoir, Fomite, Incubation period, Portal of exit, Vector.
Diseases InfectionPortal of entry: It refers to the site or pathway through which an infectious agent enters the body of a susceptible host, allowing the agent to establish an infection.
Vector: A vector is a living organism, usually an insect or animal, that transmits disease-causing pathogens from one host to another. It serves as an intermediate carrier of the infectious agent.
Reservoir: Reservoir refers to a population or environment where a pathogen lives and multiplies, serving as a source of infection. The pathogen depends on the reservoir for its survival and can be transmitted from the reservoir to susceptible individuals.
Fomite: A fomite is an inanimate object or surface that becomes contaminated with disease-causing agents, such as bacteria or viruses. These agents can survive on fomites and potentially transmit infection if they come into contact with a susceptible individual.
Incubation period: The incubation period is the interval between exposure to a pathogen and the appearance of the first signs and symptoms of the disease. It represents the time required for the pathogen to replicate and cause noticeable illness in the infected individual.
Portal of exit: It refers to the site or pathway through which an infectious agent leaves the body of an infected individual, allowing it to be transmitted to other hosts. Examples of portals of exit include respiratory secretions, feces, blood, or skin lesions.
Vector: As mentioned earlier, a vector is a living insect or animal that plays a role in transmitting disease. It can acquire the pathogen from an infected host and transmit it to a susceptible individual, potentially causing disease in the process.

In the exercise, X is a binomial variable with n = 5 and p = 0.4. Compute the given probability. Check your answer using technology. HINT [See Example 2.] (Round your answer to five decimal places.) P(X ≤ 2)
The probability of P(X ≤ 2) is 0.0135
We have the information available from the question:
Binomial variable is X
the value of n = 5
and, the value of p = 0.4
We are given to compute the probability P(X [tex]\leq[/tex] 2) and round the answer to five decimal places.
The binomial distribution formula is given by:
[tex]P(X)=nCx(p)^x(1-q)^n^-^x[/tex]
Where (nCx) means combinatory and it's given by this formula:
[tex]nCx=\frac{n!}{(n-x)!x!}[/tex]
We have to find the probability:
P(X [tex]\leq[/tex] 2) = P(X=1) + P(X=2)
P(X = 1) = [tex]5C1(0.4)^1(1-0.4)^5^-^1[/tex] = 0.0026
P(X= 2) =[tex]5C2(0.4)^2(1-0.4)^5^-^2[/tex] = 0.0109
P(X [tex]\leq[/tex] 2) = P(X=1) + P(X=2)
P(X [tex]\leq[/tex] 2) = 0.0026 + 0.0109
P(X [tex]\leq[/tex] 2) = 0.0135

A group of college students are going to a lake house for the weekend and plan on renting small cars and large cars to make the trip. Each small car can hold 4 people and each large car can hold 6 people. The students rented twice as many large cars as small cars, which altogether can hold 48 people. Graphically solve a system of equations in order to determine the number of small cars rented, x,x, and the number of large cars rented, yy.
Answer:
The students rented 3 small cars and 6 large cars.
Step-by-step explanation:
Since a group of college students are going to a lake house for the weekend and plan on renting small cars and large cars to make the trip, and each small car can hold 4 people and each large car can hold 6 people, and the students rented twice as many large cars as small cars, which altogether can hold 48 people, to determine the number of small cars rented, X, and the number of large cars rented, Y, the following calculation must be performed:
4X + 6Y = 48
4x4 + 6x8 = 16 + 48 = 64
4x3 + 6x6 = 12 + 36 = 48
Thus, the students rented 3 small cars and 6 large cars.
You are going to install a 15-metre long fence. If the posts are 3 metres apart, how many fence posts will you need? Select the best way to demonstrate the answer to students
Answer : 6 fence posts. The best way to demonstrate the answer to students is to use the formula
Explanation: To install a 15-metre long fence, the posts are 3 metres apart, how many fence posts will you need? The best way to demonstrate the answer to students is to use the formula: Total number of posts = (Length of fence ÷ Distance between posts) + 1
Where;Length of the fence = 15 metres, Distance between posts = 3 metres
Total number of posts = (15 ÷ 3) + 1 Total number of posts = 5 + 1 = 6 Therefore, you will need 6 fence posts.
The best way to demonstrate the answer to students is to use the formula: Total number of posts = (Length of fence ÷ Distance between posts) + 1

Compare the two functions below in two complete sentences.
Help
Answer:
I guess we have the table:
x f(x)
-4 7
-2 5
0 3
2 1
4 - 1
To find the slope of this, we need to select two different points (x1, y1) and (x2, y2) and use the relation:
slope = (y2 - y1)/(x2 - x1)
let´s use the first two:
(-4,7) and (-2, 5)
Slope = (5 - 7)/(-2 - (-4)) = -2/2 = -1
Now, if we want to be sure that this is a linear equation, we should do the same for other two pairs of points, now use the first and the third:
(-4, 7) and (0,3)
S = (3 - 7)/(0 -(-4)) = -4/4 = -1
Now, for the function g(x) we can see a constant line, that is parallel to the x-axis.
This means that the slope of this function is equal to zero.
This means that the slope of g(x) is bigger than the slope of f(x), because 0 > 1 i guess

Find the coordinates of the endpoint of the image?
Given:
The graph of a line segment.
The line segment AB translated by the following rule:
[tex](x,y)\to (x+4,y-3)[/tex]
To find:
The coordinates of the end points of the line segment A'B'.
Solution:
From the given figure, it is clear that the end points of the line segment AB are A(-2,-3) and B(4,-1).
We have,
[tex](x,y)\to (x+4,y-3)[/tex]
Using this rule, we get
[tex]A(-2,-3)\to A'(-2+4,-3-3)[/tex]
[tex]A(-2,-3)\to A'(2,-6)[/tex]
Similarly,
[tex]B(4,-1)\to B'(4+4,-1-3)[/tex]
[tex]B(4,-1)\to B'(8,-4)[/tex]
Therefore, the endpoint of the line segment A'B' are A'(2,-6) and B'(8,-4).
n a contingency table, when all the expected frequencies are equal the oberved frequencies the calculaed chi squared statistic equals zero. True or False
The given statement "When all the expected frequencies are equal the observed frequencies the calculated chi squared statistic equals zero." is true because chi-squared statistic will be zero in this case.
In a contingency table, the expected frequencies are calculated based on certain assumptions and can be different from the observed frequencies. The chi-squared statistic is used to determine whether there is a significant association between the variables in the contingency table.
When all the expected frequencies are equal to the observed frequencies, it means that there is a perfect match between the observed data and what would be expected under the assumption of independence.
In this case, the chi-squared statistic will be zero, indicating no discrepancy between the observed and expected frequencies.
This scenario is highly unlikely to occur in real-world data because observed frequencies typically deviate from the expected frequencies due to sampling variability or factors influencing the relationship between variables.
In most cases, the expected frequencies will differ from the observed frequencies, resulting in a non-zero chi-squared statistic, indicating a significant association or departure from independence between the variables.

1. Prove that at any party of 31 people, there’s always a person who knows an even number of others. (Assume that acquaintance is mutual: if Alice knows Zelda, then Zelda knows Alice.)
To prove that at any party of 31 people, there's always a person who knows an even number of others, we can use the pigeonhole principle.
The pigeonhole principle states that if we distribute more than "n" objects into "n" boxes, then at least one box must contain more than one object. In this case, the "objects" represent the people at the party, and the "boxes" represent the number of people each person knows.
Let's assume, for the sake of contradiction, that every person at the party knows an odd number of others. This means that each person has an odd number of acquaintances.
Now, let's consider the sum of the number of acquaintances for all 31 people. Since each person knows an odd number of others, the sum of odd numbers is also an odd number.
However, if we count the total number of acquaintances in a group, it must be even since each acquaintance involves two people. This creates a contradiction because we cannot have both an odd and an even sum for the total number of acquaintances.
Therefore, our assumption that every person knows an odd number of others must be false. Hence, there must be at least one person at the party who knows an even number of others.

1. An exponential function is shown below.
f (x)= -2(2)
Which key attribute does the function not exhibit?
This question seems extremely odd to me. I don't really even understand what's being asked.
As far as exponential functions go, it's missing an exponent for one. The dependent variable is missing. This essentially saying f(x) = -4 or y = -4. Which is fine, but is definitely not an exponential function and in a very odd and incomplete form to begin with.
