The probability a random selected person will receive a flu is 0.6031
What is Probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
To solve this problem, we just simply need to just find the decimal value of the given fraction.

Given:
a) The radius is doubled.
b) The radius is tripled.
To find:
The changes to the surface area of a sphere
Explanation:
Let us take the original radius as r.
The surface area of the original sphere is,
[tex]A=4\pi r^2[/tex]a) The new radius will be,
[tex]R=2r[/tex]So, the surface area of the sphere with the new radius is,
[tex]\begin{gathered} A=4\pi R^2 \\ =4\pi(2r)^2 \\ =4\pi(4r^2) \\ A=4(4\pi r^2) \\ A=4\times Surface\text{ area of old sphere} \end{gathered}[/tex]Therefore, the surface area of a sphere becomes four times the original surface area if the radius is doubled.
b) The new radius will be,
[tex]R=3r[/tex]So, the surface area of the sphere with the new radius is,
[tex]\begin{gathered} A=4\pi R^2 \\ =4\pi(3r)^2 \\ =4\pi(9r^2) \\ A=9(4\pi r^2) \\ A=9\times Surface\text{ area of old sphere} \end{gathered}[/tex]Therefore, the surface area of a sphere becomes nine times the original surface area if the radius is tripled.

Which statement allows the line q and p are parallel ?
According to the converse of corresponding angles theorem, the statement that allows Carmen to conclude that lines p and q are parallel is: ∠2 ≅ ∠6.
What is a Transversal?A transversal is a line that crosses two straight lines. For example, line t is a transversal that crosses the lines p and q in the given diagram above.
What are Parallel Lines?Parallel lines are lines that do not meet each other at any point and are of equal distant to each other.
When a transversal intersects two parallel lines, they form angle pairs. One of such angle pairs is, corresponding angles, which are always congruent to each other.
Thus, if corresponding angles are formed and are equal to each other, then the lines they lie on must be parallel lines based on the corresponding angles converse theorem.
Angles 2 and 6 are corresponding angles that are formed by the transversal that intersects lines q and p. If they are congruent angles, then the lines are parallel.
Therefore, Carmen can use the statement, ∠2 ≅ ∠6 to show that lines q and p are parallel.

(See Example 5.)
a. Interpret the terms and coefficient in the equation.
b. Find the domain of the function. Is the domain
discrete or continuous? Explain.
c. Graph the function using its domain.
Considering the given linear function, it is found that:
a)
The intercept is of 10, meaning that initially you have $10.The slope is of -1.44, meaning that the cost of printing each photo is of 1.44.b) The discrete domain of the function is: {0, 1, 2, 3, 4, 5, 6, 7}.
c) The graph of the function is given at the end of the answer.
What is a linear function?A linear function, in slope-intercept format, is modeled according to the rule given below:
y = mx + b
In which:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the y-axis(x = 0).The amount of money you have remaining after printing p photographs is modeled by the following function:
M(p) = 10 - 1.44p.
Hence the coefficients are as follows:
The intercept is of b = 10, meaning that initially you have $10 to spend on printing photos.The slope is of -1.44, meaning that the cost of printing each photo is of 1.44, that is, for each photo you print, you are going to lose $1.44 from your amount.The number of photos printed is a discrete number, as this number cannot assume decimal values, hence the domain is also discrete.
You cannot print a negative value of numbers, neither can M(p) be negative, hence the domain, which is the number of photos you can print, is:
{0, 1, 2, 3, 4, 5, 6, 7}.
Considering the above domain, the graph of the function is given by the image at the end of the answer.

Alice plans to buy a house. She has $2,000 in her savings account.
She plans to contribute $150 to the account each month.
We know that with each month, n, she deposits $150 and so, each month, her savings account balance increases by $150.
This simply means that after n months, her savings account balance would have increased by:
150 * n = 150n
Her initial balance was $2000, therefore, her balance after n months will be the sum of 150n and the amount that was initially there.
That is:
f(n) = 2000 + 150n

⇒ y - y₁ = [(y₂ - y₁)/(x₂ -x₁ )](x - x₁ )
Here x₁ = 0 and y₁ = 1
x₂ = 3 and y₂ = 0
The equation of the line is obtained by substituting these values into the above equation;
⇒ y - 1 = [(0-1)/(3-0)](x -0)
⇒ y - 1 = (-1/3)x
⇒ 3y - 3 = x
⇒ 3y + x = 3
The equation of the line through pair of points (1/2,2/3) and (-3/2,5/3)
⇒ y - 2/3 = [(5/3 -2/3)/(-3/2-1/2)](x -1/2)
⇒ y - 2/3 = [(3/3)/(-4/2)](x -1/2)
⇒ y - 2/3 = (1/3)(x -1/2)
Multiply by 6 both sides of the equation,
⇒ 6y - 4 = 2(x -1/2)
⇒ 6y = 2x -1 + 4
⇒ 6y = 2x +3
The equation of the line through pair of points (-3,-2) and (1,6)
