consider an undirected graph that has 100 vertices. for any pair of vertices, only 1 edge can connect them. in other words, you cannot have 2 edges connecting vertex a directly to vertex b. also assume that there are no self-loops, i.e. an edge that goes from vertex a to vertex a. what is the maximum number of edges that can be in this specific graph?
Answers
So the maximum number of edges in an undirected graph with 100 vertices is 4950.
In an undirected graph, each edge connects two vertices, and as such, it is counted twice, once for each vertex it connects. Therefore, the total number of edges in the graph is the sum of the degrees of all vertices, divided by 2.
In a complete graph with n vertices, every vertex is connected to every other vertex, except itself, and so the degree of each vertex is n-1 (it is connected to n-1 other vertices). Therefore, the total number of edges in the graph is:
n * (n-1) / 2
Substituting n = 100, we get:
100 * 99 / 2 = 4950

adriannas bedroom has a perimiter of 90 feet the width is 15 feet what is the length of her bedroom?
Answers
The length of Adrianna's bedroom that has a perimeter of 90 feet and a width of 15 feet is 30 feet.
To find the length of Adrianna's bedroom, we can use the formula for the perimeter of a rectangle:
P = 2l + 2w
where P is the perimeter, l is the length, and w is the width.
We are given that the perimeter is 90 feet and the width is 15 feet, so we can substitute those values into the formula:
90 = 2l + 2(15)
Simplifying:
90 = 2l + 30
Subtracting 30 from both sides:
60 = 2l
Dividing both sides by 2:
30 = l

You are interested in returns to college education. You decide to use log (wage) as the dependent variable, and the main variable of interest is college education (a dummy variable, taking value 1 if an individual is college graduate, and 0, otherwise). (a) Suppose education and experience are important determinants of wage and you decide to add them in the regression. Propose a regression equation to examine the return to college education. Name variables as you wish. Be careful with notation in your answer; that is, be clear with whether you use the population regession function or the sample regression function (or fitted line) (b) Suppose you want to test whether graduates from top 10 universities fare better in the labor market. Propose a regression equation that allows a wage gap between top-10 University graduates (Group 1) and non-top-10 University graduates (Group 2). Define relevant variable(s). Write down the null and alternative hypotheses to test whether the mean log wages differ between the two groups. (c) Propose a regression equation that allows the return to college education to vary with experience. Write down the null and alternative hypotheses to test whether the return to college education vary with experience. (d) Propose a regression equation that allows the return to college education to vary with which university you graduate from (that is, whether one belongs to Group 1 or Group 2). Write down the null and alternative hypotheses to test whether the return to college education differ between the two groups.
Answers
a) Let’s assume the regression equation as follows: log(wage)i = β0 + β1College_edui + β2Experiencei + β3Experiencei^2 + ui
Where:• i is the index of individuals• College_edui is a dummy variable, taking value 1 if an individual is a college graduate, and 0, otherwise•
Experience i is the experience of i th individual• Experiencei^2 captures the squared effect of experience (i.e. the non-linear effect of experience on wage).
b) Let’s denote the variable Top10i to take value 1 if ith individual is graduated from a top 10 university, and 0 otherwise. Then, the regression equation becomes:
log(wage)i = β0 + β1College_edui + β2Top10i + β3(College_edui x Top10i) + ui
Here,β3 is the wage gap between top 10 university graduates (Group 1) and non-top 10 university graduates (Group 2).The null hypothesis (H0): β3 = 0.The alternative hypothesis (H1): β3 ≠ 0.
c) Let the regression equation be:
log(wage)i = β0 + β1College_edui + β2Experiencei + β3Experiencei^2 + β4(College_edui x Experiencei) + ui.
The null hypothesis (H0): β4 = 0 (i.e. the return to college education does not vary with experience).The alternative hypothesis (H1): β4 ≠ 0 (i.e. the return to college education varies with experience).
d) The regression equation allowing the return to college education to vary with which university you graduate from is:
log(wage)i = β0 + β1College_edui + β2Top10i + β3(College_edui x Top10i) + ui.
Here, β3 is the wage gap between the two groups (top 10 universities and non-top 10 universities).
The null hypothesis (H0): β3 = 0 (i.e. the return to college education does not differ between the two groups).

two planes just took off from reno, nv. the first plane is traveling 3.5 times as fast as the second plane. after traveling in the same direction for 6 hours, they are 1455 miles apart. what is the average speed of each plane? (hint: since they are traveling in the same direction, the distance between them will be the difference of their distances.)
Answers
The average speed of the first plane is 339.5 mph, and the average speed of the second plane is 97 mph.
To find the average speed of each plane, we can use the formula:
Speed = Distance / Time
Let's assign variables to the speeds of the two planes. Let's say the speed of the second plane is 'x' mph. Since the first plane is traveling 3.5 times as fast, the speed of the first plane would be 3.5x mph.
Now, we know that both planes have traveled for 6 hours and are 1455 miles apart. Since they are traveling in the same direction, the distance between them will be the difference of their distances. Therefore, we have:
Distance of the first plane = 3.5x * 6 = 21x miles
Distance of the second plane = x * 6 = 6x miles
The difference between their distances is 1455 miles, so we can set up the equation:
21x - 6x = 1455
Combining like terms, we get:
15x = 1455
Dividing both sides by 15, we find:
x = 97
So, the speed of the second plane is 97 mph, and the speed of the first plane is 3.5 * 97 = 339.5 mph.

How can you tell from the prime factorization of the of two numbers if their LCM is the product of the two numbers
Answers
To determine if the LCM of two numbers is the product of the two numbers using their prime factorization, you need to check if the numbers are coprime.
Coprime numbers have no common prime factors except for 1. If the numbers are coprime, their LCM will be equal to the product of the two numbers.
To tell if the LCM of two numbers is the product of the two numbers, you need to compare the prime factorization of the two numbers. If the prime factors of both numbers are unique (meaning they do not share any common factors), then the LCM will be the product of the two numbers. However, if the two numbers share some common prime factors, then the LCM will have to include those factors at their highest power. So, to find the LCM of the two numbers, you need to take the highest power of each prime factor that appears in either number and multiply them together. If the product of these highest powers matches the product of the two numbers, then the LCM is equal to the product of the two numbers.

Answers
Mr. Fillbach will be able to have orange juice before having to buy more juice for 16 mornings.
The gallon is a unit of volume in imperial units and us a customary device. 3 one-of-a-kind variations are in modern use: the imperial gallon.
A clean manner to discern from liters to gallons, for an instance, is that a quart is a bit much less than a liter and 4 liters is a touch extra than 1 gallon. To be specific, 1 liter is 0.264 gallons (a bit greater than a quart), and four liters is 1.06 gallons. Q-I need to shop for a 35 mm. A gallon is equal to approximately 3.78541 liters. consequently, a gallon is larger than 3 liters.
Cups and liters each measure the extent of beverages, so whether or not you need to know how many cups are in a liter or water, oil or a bottle of soda, there will constantly be approximately four.3 cups in a liter! The liter is a metric measurement closest to the quart in imperial measurements.

Thus, beginning with a 1 = 5, the formula a n = a n-1 + 7 can be used to recursively find the nth term of the sequence.
what is sequence ?A sequence in mathematics is an ordered collection of numbers that is typically defined by a formula or rule. Every number in the series is referred to as a term, and its location within the sequence is referred to as its index. Depending on whether the list of terms stops or continues indefinitely, sequences can either be finite or infinite. By their patterns or uniformity, sequences can be categorised, and the study of sequences is crucial to many areas of mathematics, such as calculus, number theory, and combinatorics. Mathematical, geometrical, and Fibonacci sequences are a few examples of popular sequence types.
given
The sequence's terms are all different by 7 (i.e., 12 - 5 = 19 - 12 = 26 - 19 =... = 7).
The following is a definition of a recursive formula for the nth element of the sequence:
a 1 = 5 (the first term of the series is 5) (the first term of the sequence is 5)
For n > 1, each term is derived by adding 7 to the preceding term, so a n = a n-1 + 7.
Thus, beginning with a 1 = 5, the formula a n = a n-1 + 7 can be used to recursively find the nth term of the sequence. For instance, we have
a_2 = a_1 + 7 = 5 + 7 = 12
a_3 = a_2 + 7 = 12 + 7 = 19
a_4 = a_3 + 7 = 19 + 7 = 26

Point C which is 2/3 from point A to point B.
To find:
The y-coordinate of point C.
Solution:
Let the coordinates of point C are (a,b).
Point C which is 2/3 from point A to point B.
AC:AB = 2:3
AC:CB = AC:(AB-AC) = 2:(3-2) = 2:1
Section formula: If a point divides the line segment in m:n, then then
\(Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)\)
Point C divides AB in 2:1, soby section formula
\(C=\left(\dfrac{2(-6)+1(-2)}{2+1},\dfrac{2(5)+1(-1)}{2+1}\right)\)
\(C=\left(\dfrac{-12-2}{3},\dfrac{10-1}{3}\right)\)
\(C=\left(\dfrac{-14}{3},\dfrac{9}{3}\right)\)
\(C=\left(\dfrac{-14}{3},3\right)\)
Therefore, the y-coordinated of point C is 3.
