The angles that are formed by the parallel lines and the transversal are:

1. Vertical Angles

2. Same-side Exterior Angles

3. Corresponding Angles

4. Alternate Interior Angles

5. Alternate Exterior Angles

6. Same-side Interior Angles

7. Adjacent Angles

The following are special angle pairs that are formed when a transversal intercepts two parallel lines:

1. Vertical Angles: These are nonadjacent angles that share the same vertex and are directly opposite each other. An example of such angle pair is angle 6 and angle 7.

2. Same-side Exterior Angles: These are exterior angles that lie on the same side of a transversal but on sperate parallel lines. Example include angle 2 and angle 8.

3. Corresponding Angles: These angles are located on each parallels lines that are cut across by a transversal and lie relatively in the same corner to each other. An example is, angle 1 and angle 5.

4. Alternate Interior Angles: an example of such pair of interior angles that lie on opposite side of a transversal is, angle 3 and angle 6.

5. Alternate Exterior Angles: An example of a pair of alternate exterior angle is angle 2 and 7.

6. Same-side Interior Angles: These pair of angles are interior angles on the same side of a transversal. Example of such pair of angles is, angle 4 and angle 6.

7. Adjacent Angles: These are angles that share a common side and a vertex, an example is: angle 1 and angle 2.

The probabilities that have been calculated here are:

The probability that he is a smoker = 0.08 + 0.16

= 0.24

The given probability that has been calculated is 0.24.

The probability that he does not have lung disease = 0.16 + 0.73

= 0.89

The probability that he has lung disease given that he is a smoker

= 0.08 / 0.08 + 0.16

= 0.08 / 0.24

= 0.333

The probability here is calculated to be 0.333

The probability that he has lung cancer given that he does not smoke

Ratio is a comparison tool for like-kind amounts. A:B or a/B is the ratio formula for two numbers, a and b. A ratio is considered to be in proportion when two or more ratios are equal. Fractions form the foundation of the ratio and proportion concepts. The primary pillars on which many other mathematical notions are built are ratio and proportion. When comparing heights, weights, distances, or times, or when adding ingredients to a recipe, for example, ratio and proportion can be used to solve a variety of everyday problems. Ratios are created by dividing two amounts, and proportions are created when two ratios are equivalent. Different ways, such as x: y or x/y, can be used to express a ratio.

The length of the diameter of the circle is found as the 2×(√5).

,

For the given question;

The equation of the circle is given as;

(x-4)^2+(y-2)^2=5

Comparing the equation of the circle with the standard form.

Radius r² = 5

Then, r = √5

Now, the diameter is the twice of the radius.

Diameter = 2×radius

Diameter = 2×(√5)

Thus, the length of the diameter of the circle is found as the 2×(√5).

The volume of the rectangular prism is the product of the base area and the height.

Given that the volume of a rectangular prism is 6,142.5 cm³. The height is 16.25 cm and the length is 28 cm

The volume of the rectangular prism

V = Length × Width × Height

6,142.5 = 28 × Width × 16.25

Apply the multiplication operation,

6,142.5 = 455 × Width

Width = 6,142.5 / 455

Apply the division operation, and we get

Width = 13.5 cm

Hence, the value of the width is 13.5 cm.

On comparing the given expressions we get-

[tex]9^{-2} < (\frac{1}{9}) ^{-1}[/tex]

[tex](\frac{1}{9}) ^{-1} < (\frac{1}{9}) ^{-2}[/tex]

[tex]9^{-1} > 9^{-2}[/tex]

Here, we are given 3 pairs of expression. Let us evaluate them one by one.

[tex]9^{-2}[/tex] _ [tex](\frac{1}{9}) ^{-1}[/tex]

The negative exponent means that the base is the reciprocal raised to a positive power. Thus, [tex]9^{-2}[/tex] can be written as- [tex](\frac{1}{9}) ^{2}[/tex] = 1/81

similarly, [tex](\frac{1}{9}) ^{-1}[/tex] can be written as- [tex](9}) ^{1}[/tex] = 9

Thus, the expression becomes-

1/81 _ 9

clearly we can see that 1/81 < 9

Now, we have [tex](\frac{1}{9}) ^{-1}[/tex] _ [tex](\frac{1}{9}) ^{-2}[/tex]

As shown above, the expression can be simplified as-

[tex](9) ^{1}[/tex] _ [tex](9) ^{2}[/tex]

9 _ 81

clearly we can see that 9 < 81

Next, we have- [tex]9^{-1}[/tex] _ [tex]9^{-2}[/tex]

we can write this as-

1/9 _ 1/81

Clearly, 1/9 > 1/81

[tex]\textsf{when $b^2-4ac > 0 \implies$ two real roots}.[/tex]

[tex]\textsf{when $b^2-4ac=0 \implies$ one real root}.[/tex]

[tex]\textsf{when $b^2-4ac < 0 \implies$ no real roots}.[/tex]

Given function:

[tex]x^2+x-2=0[/tex]

Therefore:

Substitute the values of a, b and c into the discriminant formula:

[tex]\begin{aligned} \implies b^2=4ac&=(1)^2-4(1)(-2)\\&=1-4(-2)\\&=1+8\\&=9\end{aligned}[/tex]

Therefore, the discriminant of the given function is 9.

As the discriminant is greater than zero, this implies that there are two real roots.

Albert floating in hot air balloon and Isabelle standing at ground are 29 meters far apart from each other.

What is hot air balloon?

A hot air balloon is a lighter in weigh than air. It is an object made up of an envelope-like bag that holds heated air. A wicker basket, gondola, or capsule suspended below transports people and a heat source, typically an open flame produced by burning liquid propane. A capsule also carries passengers in some long-distance or high-altitude balloons.

Lets understand with the help of a right angle triangle, The point from where the hot air balloon taken off be point A, and the point where Isabelle is standing is point B, and the point where the balloon is point C.

The AB= distance between Isabelle and the point from where hot air  balloon taken off = base of the imagined triangle,

AC = height at which hot air balloon is floating = perpendicular of the imagined triangle

BC = distance between Isabelle and hot air balloon = Hypotenuse of the imagined triangle

Applying Pythagoras theorem,

(BC)² = (AC)² + (AB)²

(BC)² = (20)² + (21)²

BC = 29

Hence Albert and Isabelle are 29 meters far apart.

The equation of a line is given by

where m is the slope of the line and (x1,y1) is a point where the line passes through.

In our case we have a point but we don't have the slope yet, so we have to find it. To do this we have to remember that two lines are parallel if and only if their slopes are equal, that is

We know that the line we are looking for is parallel to the line

we notice that this line in written in the slope-intercept form

then its slope is 13.

Since the line is parallel to the one we are looking for, our slope is also 13.

Using the point (9,12) and the slope the equation of the line is

now we have to write in the slope-intercept form

Therefore the line is
