what does the degree of a vertex in the hollywood graph represent? what does the neighborhood of a vertex repre- sent? what do the isolated and pendant vertices represent?
The degree of a vertex represents the number of other actors or actresses that an actor or actress has worked with in movies.
The neighborhood of a vertex represents the set of actors or actresses that an actor or actress has worked with in movies.
Isolated vertices represent actors or actresses who have not worked with any other actors or actresses in any movie, while pendant vertices represent actors or actresses who have only appeared in one movie with another actor or actress in the Hollywood graph.
The Hollywood graph is an undirected graph because the relationship between actors and actresses is mutual.
Each vertex in this graph represents an actor or actress, and the degree of a vertex represents the number of other actors or actresses that they have worked with in movies. In other words, the degree of a vertex represents the number of edges that are connected to that vertex.
The neighborhood of a vertex in a graph refers to the set of all vertices that are adjacent to it. In the context of the Hollywood graph, the neighborhood of a vertex represents the set of actors or actresses that a particular actor or actress has worked with in movies.
An isolated vertex in a graph is a vertex that has no edges connected to it. In the context of the Hollywood graph, an isolated vertex represents an actor or actress who has not worked with any other actors or actresses in any movie.
A pendant vertex in a graph is a vertex that has only one edge connected to it. In the context of the Hollywood graph, a pendant vertex represents an actor or actress who has only appeared in one movie with another actor or actress in the Hollywood graph.

Write the equation in standard form of the line y=1/9x+5
The equation in standard form is x - 9y = -45.
What is the Equation of a Line in Standard Form?The equation of a line in standard form is Ax + By = C, where x and y are variables and A, B and C are integers.
Given equation is y = 1/9 x + 5.
Here 1/9 is not an integer.
So multiplying the equation throughout by 9, we get,
9y = x + (5 × 9)
9y = x + 45
Subtracting both sides by x,
9y - x = 45
-x + 9y = 45
Multiplying throughout by -1,
x - 9y = -45, which is in standard form.
Hence the equation is x - 9y = -45 in standard form.

Answer:
a = 6 ft.
------------------------------
Given is an isosceles right triangle.
As per property of a such triangle, its hypotenuse is √2 times its leg.
That is:
a√2 = 6√2, divide both sides by √2a = 6Answer:
a = 6 ft
Step-by-step explanation:
We have to find,
→ The value of a in the diagram.
Formula we use,
=> Using Pythagoras theorem.
→ (Hyp)² = (Opp)² + (Base)²
Forming the equation,
→ (6√2)² = (a)² + (a)²
Now the value of a will be,
→ (6√2)² = (a)² + (a)²
→ (a)² + (a)² = (6√2)²
→ 2a² = 36 × 2
→ 2a² = 72
→ a² = 72 ÷ 2
→ a² = 36
→ a = √(36)
→ [ a = 6 ft ]
Hence, the value of a is 6 ft.

O-16x² + 10x - 14x
O-16x³ + 10x² - 14x
Answer:
-16x² + 10x - 14.
Step-by-step explanation:
To find the composition of two functions, (f g)(x), we first evaluate g(x) and then substitute the result into f(x).
So, let's first evaluate g(x):
g(x) = 8x² - 5x + 7
Next, substitute g(x) into f(x):
(f g)(x) = f(g(x)) = f(8x² - 5x + 7) = -2(8x² - 5x + 7) = -16x² + 10x - 14
Therefore, (f g)(x) = -16x² + 10x - 14.

60 children choose their favourite fruit out of apples bananas and watermelon 30% chose apples and 25% chose bananas How many children chose watermelon
Answer:
27 children.
Step-by-step explanation:
Let's call the number of children who chose apples x. Then, the number of children who chose bananas is 0.25x. The number of children who chose watermelon is 60 - x - 0.25x = 60 - 1.25x.
Since 30% of the children chose apples, we know that:
0.30 * 60 = x
So, x = 18, which means 18 children chose apples.
And since 25% of the children chose bananas, we know that:
0.25 * 60 = 0.25x = 15
So, 15 children chose bananas.
Finally, the number of children who chose watermelon is:
60 - 18 - 15 = 27 children.
A right triangle has legs measuring 20 in. and 28 in. what is the length of the hypotenuse? round to the nearest tenth. responses 8.0 in. 8.0 in. 19.6 in. 19.6 in. 34.4 in. 34.4 in. 1184.0 in.
The length of the hypotenuse of a right triangle with legs measuring 20 inches and 28 inches is approximately 34.4 inches, found using the Pythagorean theorem.
The length of the hypotenuse of a right triangle with legs measuring 20 inches and 28 inches can be calculated using the Pythagorean theorem, which states that the square of the sum of the squares of the lengths of the legs determines the length of the hypotenuse.
So, if we call the length of the hypotenuse "h", we have [tex]h^{2}[/tex] = [tex]20^2 + 28^2[/tex]
Solving for h:
[tex]h^2 = 20^2 + 28^2[/tex]
[tex]h^2[/tex] = 400 + 784
[tex]h^2[/tex] = 1184
h = [tex]\sqrt{1184}[/tex]
h ≈ 34.4 in.
So, the length of the hypotenuse is approximately 34.4 inches, rounded to the nearest tenth.
The Pythagorean theorem is a fundamental mathematical relationship that states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal tothe squared lengths of the two legs added together. In this case, the two legs have lengths of 20 inches and 28 inches, and the length of the hypotenuse can be found by solving for the square root of the total of the leg squares.

16. The diagram shows a sketch of the graph y = ab^x where b>0
The curve passes through the points A (1, 10) and B (4,80).
The point C (-1, k) lies on the curve.
Find the value of k.
I don’t what exponential graphs are and I don’t understand what the question means!!!
Answer:
k is 2.5.
Step-by-step explanation:
To find the value of k, we can use the information given about points A and B to find the value of the parameters a and b. Since we know that the curve passes through A (1, 10) and B (4, 80), we can substitute these points into the equation y = ab^x to find the values of a and b.
Starting with point A:
10 = a * b^1
Next, using point B:
80 = a * b^4
We can now use these two equations to find the value of b:
10 = a * b^1
80 = a * b^4
Dividing the second equation by the first equation:
8 = b^3
Taking the cube root of both sides:
b = 2
We can now use either of the two equations to find the value of a:
10 = a * b^1
a = 10/2 = 5
Now that we have found the values of a and b, we can substitute the point C (-1, k) into the equation y = ab^x to find the value of k:
k = 5 * 2^(-1) = 5 * (1/2) = 2.5
So the value of k is 2.5.

uppose that shoe sizes of american women have a bell-shaped distribution with a mean of 8.06 and a standard deviation of 1.52 . using the empirical rule, what percentage of american women have shoe sizes that are between 6.54 and 9.58 ?
Using the empirical rule, we can conclude that approximately 68% of American women have shoe sizes between 6.54 and 9.58.
Using the empirical rule, we can say that approximately 68% of the data falls within one standard deviation of the mean, approximately 95% of the data falls within two standard deviations of the mean, and approximately 99.7% of the data falls within three standard deviations of the mean.
To find the percentage of American women who have shoe sizes between 6.54 and 9.58, we first need to standardize these values by subtracting the mean and dividing by the standard deviation:
z1 = (6.54 - 8.06) / 1.52 = -1.00
z2 = (9.58 - 8.06) / 1.52 = 1.00
Now, we can use the empirical rule to find the percentage of women with shoe sizes between z = -1.00 and z = 1.00. Since this interval corresponds to one standard deviation from the mean, we know that approximately 68% of the data falls within this range.

Which proportion can be used to find the length of sides ik
The proportion i/k = 12 can be used to find the length of sides i and k if the perimeter is 12 units. To solve for the length of each side, the equation i + k = 12 is used, and then the two sides are divided by each other to get the proportion i/k = 12.
The proportion i/k = 12 can be used to find the length of sides i and k of a shape if the perimeter is 12 units. In order to solve for the length of each side, the equation i + k = 12 is used to determine the sum of the sides. The two sides are then divided by each other, resulting in the proportion i/k = 12. This proportion can then be used to find the length of sides i and k. For example, if the length of side i is 8, then the length of side k is 4. This can be determined by dividing 8 by 4, which results in the proportion i/k = 2. If the perimeter is 12 units, then the equation i + k = 12 can be used to determine that the length of side i is 6 and the length of side k is 6, since 6 + 6 = 12. The proportion i/k = 12 can then be used to confirm that the length of side i is 6 and the length of side k is 6.

Convert milligrams per liter to micrograms per (fluid ounce)
To convert milligrams per liter (mg/L) to micrograms per fluid ounce (µg/fl oz), we can use the conversion factor of 29.5735.
This conversion factor takes into account the difference in volume between a liter and a fluid ounce.
1 fl oz = 29.5735 mL
1 L = 1000 mL
So, to convert from milligrams per liter to micrograms per fluid ounce, we divide by 29.5735 and multiply by 1000:
(mg/L) * 1000 / 29.5735 = (µg/fl oz)
Therefore, to convert a value x from milligrams per liter to micrograms per fluid ounce:
x (µg/fl oz) = x (mg/L) * 1000 / 29.5735
