Answers
The correct order of the set of numbers from least to greatest is 2, 3 over 4, 2.71 repeating 71, 5 over 2, square root 5 option (D) is correct.
To order the given set of numbers from least to greatest, we need to compare their values. We start by noticing that 2 and 3 over 4 are equivalent to 2.75. Next, we compare the values of the remaining numbers. Since the square root of 5 is approximately 2.236 and 5 over 2 is equivalent to 2.5, we have:
2, 3 over 4 < 2.71 repeating 71 < 2.5 < square root 5
Therefore, the set of numbers in order from least to greatest is 2, 3 over 4, 2.71 repeating 71, 5 over 2, square root 5.
Ordering the set of numbers from least to greatest, we get:
2, 3 over 4, 2.71 repeating 71, square root 5, 5 over 2.

the hypotenuse of a triangle is 4x one of the legs . the other leg in 3(sqrt 5 units. find the length of the hypotenus?
Answers
The length of the hypotenuse is 4√3 units.
Given that hypotenuse is 4 times the length of one leg of a triangle. So here we can assume that length to be x. Hence the hypotenuse length is 4x. To calculate hypotenuse we have the formula a²=b² + c², where b and c are two sides of the triangle and a is the hypotenuse. If we put these values in the formula we get,
16x² = x² + (3√5)²
15x² = 45
x² = 3
x = ±√3
Since length cannot be negative, the final value of x = √3, and since the length of the hypotenuse was 4x, the final value of the hypotenuse is 4√3.

Convert the following decimal numbers to the binary number system. a. 8 b. 35 c. 108 d. 176
Answers
The binary representations of the given decimal numbers are: (a) 8 = 1000, (b) 35 = 100011, (c) 108 = 1101100, and (d) 176 = 10110000.
(a) To convert 8 to binary, we repeatedly divide the number by 2 and keep track of the remainders. The remainders, read in reverse order, give the binary representation.
Starting with 8, the division process yields: 8/2 = 4 with a remainder of 0, 4/2 = 2 with a remainder of 0, and 2/2 = 1 with a remainder of 0. The binary representation of 8 is 1000.
(b) To convert 35 to binary, we follow the same process. The division steps are as follows: 35/2 = 17 with a remainder of 1, 17/2 = 8 with a remainder of 1, 8/2 = 4 with a remainder of 0, 4/2 = 2 with a remainder of 0, and 2/2 = 1 with a remainder of 0. The binary representation of 35 is 100011.
(c) For 108, the division steps are: 108/2 = 54 with a remainder of 0, 54/2 = 27 with a remainder of 0, 27/2 = 13 with a remainder of 1, 13/2 = 6 with a remainder of 1, 6/2 = 3 with a remainder of 0, 3/2 = 1 with a remainder of 1. The binary representation of 108 is 1101100.
(d) Finally, for 176, the division steps are: 176/2 = 88 with a remainder of 0, 88/2 = 44 with a remainder of 0, 44/2 = 22 with a remainder of 0, 22/2 = 11 with a remainder of 0, 11/2 = 5 with a remainder of 1, 5/2 = 2 with a remainder of 1, and 2/2 = 1 with a remainder of 0. The binary representation of 176 is 10110000.

solve the cauchy problem (y+u)ux+yuy=(x-y), with u=1+x on y=1
Answers
The solution to the Cauchy problem is:
u(x,y) = x - y + e^(-(y-1))
To solve the given Cauchy problem, we can use the method of characteristics.
First, we write the system of ordinary differential equations for the characteristic curves:
dy/dt = y+u
du/dt = (x-y)/(y+u)
dx/dt = 1
Next, we need to solve these equations along with the initial condition y(0) = 1, u(0) = 1+x, and x(0) = x0.
Solving the first equation gives us y(t) = Ce^t - u(t), where C is a constant determined by the initial condition y(0) = 1. Substituting this into the second equation and simplifying, we get:
du/dt = (x - Ce^t)/(Ce^t + u)
This is a separable differential equation, which we can solve by separation of variables and integrating:
∫(Ce^t + u)du = ∫(x - Ce^t)dt
Simplifying and integrating gives us:
u(t) = x + Ce^-t - y(t)
Using the initial condition u(0) = 1+x, we find C = y(0) = 1. Substituting this into the equation above gives:
u(t) = x + e^-t - y(t)
Finally, we can solve for x(t) by integrating the third equation:
x(t) = t + x0
Now we have expressions for x, y, and u in terms of t and x0. To find the solution to the original PDE, we need to express u in terms of x and y. Substituting our expressions for x, y, and u into the PDE, we get:
(y + x0 + e^-t - y)(1) + y(Ce^t - x0 - e^-t + y) = (x - y)
Simplifying and canceling terms, we get:
Ce^t = x - x0
Substituting this into our expression for u above, we get:
u(x,y) = x - x0 + e^(-(y-1))
Therefore, the solution to the Cauchy problem is:
u(x,y) = x - y + e^(-(y-1))

Answers
Answer:
56% decreaseStep-by-step explanation:
In this problem we are required to find the percentage decrease in the value of a car that originally cost $25,000
if the present value is now $14,000
we can solve for the percentage decrease by presentment the original cost of the car by the original cost and multiplying by 100
i.e = (14,000/25,000)*100

find the area under the standard normal curve to the left of z=−1.76 and to the right of z=0.07. round your answer to four decimal places, if necessary.
Answers
The area under the standard normal curve to the left of z = -1.76 and to the right of z = 0.07 is 0.5113 square units
To find the area under the standard normal curve to the left of z = -1.76, we can use a standard normal distribution table or a calculator with a normal distribution function. The table or calculator will give us the probability that a standard normal random variable is less than or equal to -1.76.
Using a standard normal distribution table, we can find that the area to the left of z = -1.76 is 0.0392 (rounded to four decimal places).
To find the area under the standard normal curve to the right of z = 0.07, we can subtract the area to the left of z = 0.07 from the total area under the curve, which is 1. Using a standard normal distribution table or calculator, we can find that the area to the left of z = 0.07 is 0.5279. Therefore, the area to the right of z = 0.07 is
1 - 0.5279 = 0.4721
Rounding this to four decimal places, we get 0.4721.
Therefore, the area under the standard normal curve to the left of z = -1.76 and to the right of z = 0.07 is
0.0392 + 0.4721 = 0.5113

The difference between the mean and the data point farthest from the mean
The difference between the mean and the data point nearest to the mean
The difference between the mean and the median
None of the above
Source
Answers
The standard deviation measures the spread of data points around the mean. It considers all data points, not just the farthest or nearest ones. A higher standard deviation indicates a greater spread.
The standard deviation is a statistical measure that tells us how much the data points in a set vary from the mean. It provides information about the spread or dispersion of the data. To calculate the standard deviation, we take the square root of the variance, which is the average of the squared differences between each data point and the mean.
By considering all data points, the standard deviation provides a comprehensive measure of how spread out the data is. Therefore, the statement "The difference between the mean and the data point farthest from the mean" is incorrect, as the standard deviation does not focus on just one data point.
The statement "The difference between the mean and the data point nearest to the mean" is also incorrect because the standard deviation takes into account the entire data set. The statement "The difference between the mean and the median" is incorrect as well, as the standard deviation is not specifically related to the median.
Hence, the correct answer is "None of the above."

ra elaborar un pastel de 2 kg, se necesitan, ¾ de kg de harina y 4 huevos (con un peso de 100 gr cada uno), además de otros ingredientes. ¿Cuál es el peso que tienen los demás ingredientes del pastel?
Answers
Based on the above, the weight of the other ingredients in the cake is about 850 grams.
What is the weight about?To determine the weight of the other ingredients in the cake, one need to subtract the weight of the flour as well as the eggs from the total weight of the cake.
Note that from the question:
Weight of flour = ¾ kg = 750 gNumber of eggs = 4Weight of each egg = 100 gSo: Weight of flour and eggs = (Weight of flour) + (Number of eggs × Weight of each egg)
= 750 g + (4 × 100 g)
= 750 g + 400 g
= 1150 g
Hence: The Total weight of the cake = 2 kg = 2000 g
Going further:
Weight of other ingredients = Total weight of the cake - Weight of flour and eggs
= 2000 g - 1150 g
= 850 g
Therefore, the weight of the other ingredients that is seen in the cake is 850 grams.

In the tournament described in Exercise 11 of Section 2.4, a top player is defined to be one who either beats every other player or beats someone who beats the other player. Use the WOP to show that in every such tournament with n players n∈ N, there is at least one top player.
Answers
Using the Well-Ordering Principle (WOP), it can be proven that in every tournament with n players (where n is a natural number), there is at least one top player, defined as someone who either beats every other player or beats someone who beats the other player.
We will prove this statement by contradiction. Assume that there exists a tournament with n players where there is no top player. This means that for each player, there exists either another player who beats them or a chain of players such that each player beats the next one. Now, consider the set S of all players in this tournament. Since S is a non-empty set of natural numbers, it has a least element, let's say k.
Now, player k either beats every other player in the tournament, making them a top player, or there exists a player, let's say player m, who beats player k. In the latter case, we have a chain of players: k, m, p_1, p_2, ..., p_t, where p_1 beats p_2, p_2 beats p_3, and so on until p_t.
However, this contradicts the assumption that there is no top player, as either player k beats every other player (if m does not exist), or player m beats someone who beats the other player (if m exists). Hence, by contradiction, we have shown that in every tournament with n players, there is at least one top player.

Step-by-step explanation:
b = # of candles Booker sold
f = # of candles Finley sold
1) b = 3f
2) f = b - 12 substitute b=3f into this equation to get an expression all in terms of f, then solve for f
f = 3f - 12
-2f = -12
f = -12/2 = 6 now plug this into either equation and solve for b
b = 3(6) = 18
