False. Consider a graph with 4 vertices, where there is an edge of weight 8 between the two farthest vertices, and an edge of weight 10 between the two closest vertices.
The highest weight edge (10) would be included in the MST, as it is the only connection between the two closest vertices.The definition of a minimum spanning tree states that it is a subset of edges of a graph that connect all of the vertices without forming any cycles, and with the minimum total weight. If a graph contains an edge with the highest weight, it may still be included in the MST if it is the only connection between two vertices. To illustrate this, consider a graph with 4 vertices, where there is an edge of weight 8 between the two farthest vertices, and an edge of weight 10 between the two closest vertices. In this case, the highest weight edge (10) would be included in the MST, as it is the only connection between the two closest vertices, and thus the minimum total weight is achieved.

How much more will mark’ mother pay in interet if he chooe to borrow the money from company 2?
If Mark’s mother borrows the money of $25,000 from company 2 which offers a rate of 8.5% for 3 years, she needs to pay the charge of $6375.
How to calculate the simple interest?Interest is the cost of borrowing or saving money. Simple interest is an easy method to calculate the interest charge on a loan.
As its name, calculating the simple interest is simple and quick. We only multiply the money we borrow or deposit, by the period, then multiply them by the interest rate applied by the bank or any financial institution chosen.
The formula for calculating the simple interest is
P x R x T
P means principal or how much money we borrow or save
R means rate or how many percentages of interest applied
T means time or how long we borrow or save the money
By using the formula mentioned before, the simple interest would be
$25,000 x 8.5% x 3 = $6375
Thus, the amount of simple interest paid is $6375 and the total amount paid is $25000 + $6375 = $31,375

a cylindrical water tank 5 meters high with a radius of 2 meters is buried so that the top of the tank is 1 meter below ground level. how much work is done in pumping a full tank of water up to ground level? (the water weighs 9800 newtons per cubic meter.)
The work is done in pumping a full tank of water up to ground level is 470400πNm.
Tank sizes variety from 6 ft. to one hundred twenty ft. in diameter with a roof, and as much as two hundred toes in diameter as an open pinnacle tank. Tanks with a roof have capacities starting from seven-hundred gallons to 500,000 gallons at the same time as the open pinnacle tanks may be constructed with even large capacities
The radius of the layer = 2m
V= pi (2)^2 (Delta y) m^3 = four pi Delta y m^3V=π(2) 2 (Δy)m 3 =4πΔym 3

[C] $6,148.05
The solution is Option A.
The amount after 9 years with an investment of $ 7000 at a simple interest calculated quarterly at rate 2.05 is $ 7,322.88
What is Simple Interest?
Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.
Simple Interest = ( Principal Amount x Rate x Time Period ) / 100
Given data ,
Let the simple interest be represented as I
Now , the amount invested P = $ 7,000
The rate of interest R = 2.05 %
The time period t = 9 years
Since the interest is calculated quarterly , t= T/4
Now , the simple interest is calculated by the formula
Simple Interest = ( Principal Amount x Rate x Time Period ) 100
Substituting the values in the equation , we get
Simple Interest I = [ ( 7000 x 2.05 x 9 ) / 4 ] / 100
On simplifying the equation , we get
Simple Interest I = ( 129150 ) / 400
Simple Interest I = $ 322.875
I = $ 322.88
Now , the amount after 9 years = initial amount P + Interest I
Amount after 9 years = 7,000 + 322.88
Amount after 9 years = $ 7,322.88
Hence , the amount after 9 years is $ 7,322.88

Consider a game in which each play costs one nickel (1¢). During each play, the game dispenses a coin to the player to keep. The game machine contains equal numbers of pennies (1¢), nickels, dimes (10¢), and quarters (25¢). The nickels that the player inserts do not go into the same pool of "reward" coins. What is the expected profit, in cents, for a player who plays five games in a row?
The expected profit, in cents, for a player who plays 1 game is 5.25 cents.
How to obtain the expected profit?The distribution that models the profit of a player for a single game is given as follows:
P(X = -4 cents) = 0.25. -> pays 5 cents, wins 1 cent, loses 4 cents.
P(X = 0 cents) = 0.25. -> pays 5 cents, wins 5 cents.
P(X = 5 cents) = 0.25. -> pays 5 cents, wins 10 cents.
P(X = 20 cents) = 0.25. -> pays 5 cents, wins 25 cents.
The expected value of a discrete distribution is computed by adding the total of each outcome and multiplying it by its probability, as follows:
E(X) = -4 x 0.25 + 0 x 0.25 + 5 x 0.25 + 20 x 0.25
E(X) = 5.25 cents.
Hence, the expected profit is 5.25 cents

-6x + 2y - 18
2y - 18
6x + 2y - 30
None of these choices are correct.
Answer:
To simplify the expression -3x + 6 - 3x - 24 + 2y, you can start by combining like terms.
-3x and -3x are both negative, so they can be combined to give -6x.
6 and -24 are both constants, so they can be combined to give -18.
So the simplified expression is: -6x - 18 + 2y
If you want to write the expression in standard form, you can rearrange the terms to give: 2y - 6x - 18

The vector field F = [tex](3x^2y + z^3, x^3 + 2yz, y^2 + 3xz^2)[/tex] has a nonzero divergence and a nonzero curl, indicating that it is not a conservative vector field. F cannot be expressed as the curl of another vector field.
To compute the divergence of F, we take the partial derivatives of each component with respect to their corresponding variables and sum them up. The divergence of F is given by div(F) = ∇·F = (∂/∂x)[tex](3x^2y + z^3)[/tex] + (∂/∂y)[tex](x^3 + 2yz)[/tex] + (∂/∂z)[tex](y^2 + 3xz^2)[/tex]. Evaluating these partial derivatives, we find div(F) = 6xy + 3z^2 + 2yz + 6xz.
To compute the curl of F, we take the curl operator (cross product of the del operator with F) and expand the determinant. The curl of F is given by curl(F) = ∇×F = (∂/∂y)[tex](y^2 + 3xz^2)[/tex] - (∂/∂z)[tex](x^3 + 2yz)[/tex], (∂/∂z)[tex](3x^2y + z^3)[/tex] - (∂/∂x)[tex](y^2 + 3xz^2)[/tex], (∂/∂x)[tex](x^3 + 2yz)[/tex] - (∂/∂y)[tex](3x^2y + z^3)[/tex].

Explain the method of substitution?Three steps make up the substitution technique: For each of the variables, solve one equation. Put this expression (or plug it in) into the other equation, then solve it. To identify the matching variable, rewrite the value's original equation.Total number of packs of plates = 54.
The set are either sets of 8 or sets of 12.
Let x represent the overall number of 12-plate packets.
There will therefore be in total packs of 8 plates: 54 - x.
Thus,
8(54−x) + 12x = 496
432 − 8x + 12x = 496

A cell phone is originally priced at $120. The store owner gives a discount and the cell phone is now priced at $90. Find the percentage discount for the cost of the cell phone,.
Answer:
25%
Step-by-step explanation:
To find the percentage discount for the cost of the cell phone, we need to first find the difference between the original price and the discounted price:
$120 - $90 = $30
Then we need to divide this amount by the original price and multiply by 100% to express the result as a percentage:
($30 / $120) * 100% = 25%
Therefore, the percentage discount for the cost of the cell phone is 25%.

under what circumstances is a discretized b state matrix equivalent to a continuous time b state matrix
A continuous time system can behave roughly throughout a variety of periods using a discretized state matrix. A continuous time condition matrix should be used in its place if these requirements are not satisfied since a discretized state matrix might not adequately depict the performance of a continuous time system.
A continuous time condition matrix is a matrix that is used to indicate the state of a system at any moment, as opposed to a discretized state matrix, which is used to describe the status of a system at discrete time intervals. Under the following conditions, a discrete-time state matrix is identical to a time series state matrix:
The system may be regarded as being in stable equilibrium at each time point since the time gaps between every discretization are short enough. This indicates that the behavior of the system does not drastically vary from one-time point to the next.
Over the time frames between each discretization, a linear model accurately predicts the behavior of the system. This means that the behavior of the system can be precisely predicted by a linear equation of the type "Ax = Bu," where A as well as B are matrices and x as well as u are vectors that, respectively, represent the system's state and input.
Over the intervals between each discretization, the system's input remains constant. This indicates that the system's input does not drastically vary from one-time point to the next.

The ratio of the same side interior angles of two parallel lines is 1:14. find the measures of all eight angles formed by the parallel lines and transversals.
Answer:
x degrees, 14x degrees, x degrees, 14x degrees, x degrees, 14x degrees, 2x degrees, and 28x degrees.
Step-by-step explanation:
The ratio of the same side interior angles of two parallel lines is 1:14, which means that for every one degree of the first angle, the second angle measures 14 degrees. If the first angle is x degrees, then the second angle is 14x degrees.
Since the lines are parallel and the angles are on the same side of the transversal, the alternate interior angles are congruent, so the measure of the third angle is also x degrees, and the measure of the fourth angle is also 14x degrees.
Since the lines are parallel, the alternate exterior angles are also congruent, so the measure of the fifth angle is also x degrees, and the measure of the sixth angle is also 14x degrees.
Finally, the measures of the seventh and eighth angles can be found by adding the measures of the adjacent angles. The seventh angle is adjacent to the third and fifth angles, so its measure is x + x = 2x degrees. The eighth angle is adjacent to the fourth and sixth angles, so its measure is 14x + 14x = 28x degrees.
In summary, the measures of the eight angles formed by the parallel lines and transversal are x degrees, 14x degrees, x degrees, 14x degrees, x degrees, 14x degrees, 2x degrees, and 28x degrees. The value of x can be determined by knowing the measure of one of the angles, or by using other information about the angles or the parallel lines.

2(4x² - 15x + 9) = 1
8x² - 30x + 18 = 1
8x² - 30x + 17 = 0
(x - 0.696)(x - 3.054) = 0
(x - 0.696) = 0 and (x - 3.054) = 0
x = 0.696 and x = 3.054
Therefore, the two possible solutions for the given equation are -
[x] = 0.696 and [x] = 3.054.

Shawna bought an antique writing
desk marked down from $6,116 to
$1,951. What percentage is the
discount?
(round your answer to the nearest percent)
Percent changes are measured by (the change in amount) divided by (the starting amount).
In this case, you'd have
[tex]\dfrac{6116-1951}{6116}=\dfrac{4165}{6116}\approx 0.6810[/tex]
This is about a 68% discount.
Sam tested every 50th candy bar from the assembly line to make sure there were enough peanuts in each bar. He found 15% did not have enough peanuts. How many candy bars do not have enough peanuts if the factory produces 20,000 candy bars?.
Here every 50th candy bar is tested . It is a sampling interval .
What does "systematic sampling" mean?
Systematic sampling is a probability sampling technique where researchers choose individuals from the population at regular intervals, such as every 15th person on a population list.
The advantages of simple random sampling can be imitated if the population is arranged randomly.
Systematic sampling is a type of probability sampling method in which sample members from a larger population are selected according to a random starting point but with a fixed, periodic interval. This interval, called the sampling interval.
Here every 50th candy bar is tested . It is a sampling interval .
Therefore he use systematic sampling plan.
