Answers

Answer 1

For c = 1, we have f(t,y) =-y = 1. Rearranging this equation yields y = 1, which simplifies to y = et. The isoclines for c = -1, 0, 1 are y = e-t, y = 0, and y = et, respectively.

c = -1: y = e-t

c = 0: y = 0

c = 1: y = et

For c = -1, we have f(t,y) = -y = -1. Rearranging this equation yields y = -1, which simplifies to y = e-t.

For c = 0, we have f(t,y) = -y = 0. Rearranging this equation yields y = 0.

For c = 1, we have f(t,y) =-y = 1. Rearranging this equation yields y = 1, which simplifies to y = et.

The isoclines for c = -1, 0, 1 are y = e-t, y = 0, and y = et, respectively.

The general solution would be (y).e = C.

The differential equation is what.

A differential equation is an equation that connects some independent variables to an unknown function and its derivatives. It is used to describe a system's behaviour that changes over time or in response to an outside factor.

There are many ways to solve the differential equation (x2 - y2) dy - 2xy dx = 0, including variable separation, integrating components, and substitution.

One possible method is separation of variables, where we separate the variables x and y by dividing both sides by x² -y2

dy/dx = 2xy/(x² -y²)

We can then integrate both sides:

[(dy/dx) dx = √(2xy/(x²-y²)) dx

y = √2xy/(x²-y²²) dx + C, where C is an arbitrary constant. solving this, (y-x).ec"

Hence, the general solution would be (y-x).e=C".

The equivalent of 120 or ten dozen is a great hundred, commonly referred to as a small gross.

What is Dozen?A group of twelve is referred to as a dozen and is frequently abbreviated as doz or dz.Given that there are roughly twelve lunar cycles (or months) in each cycle of the sun (or year), the number twelve may be one of the first primitive integer groupings. Twelve is useful because it has the greatest number of divisors among numbers up to its double, a quality shared only by the numbers 1, 2, 6, 12, 60, 360, and 2520. The duodecimal system, commonly referred to as dozenal, was developed in Mesopotamia and uses twelve as its base number (see also sexagesimal). On the hands, numbering each finger bone with the thumb makes it simple to count in base-12.By using the second hand as a stand-in for units of twelve, two hands may count to 144 using this system, which allows one hand to count to twelve.

use lagrange multipliers to find the maximum and minimum values of the function subject to the given constraint. (if an answer does not exist, enter dne.) f(x, y) = y2 − x2; 1 4 x2 y2 = 81

Answers

The critical point (0, 9) is a minimum and (0, -9) is a maximum.

Lagrange multipliers are a method used to find the maximum and minimum values of a function subject to a constraint.

To use Lagrange multipliers, we first write the function and constraint as a system of equations.

For the function

=> f(x, y) = y² − x²

and the constraint

=> 14x²y² - 81,

the system becomes:

y² − x² = λ(14x²y² − 81)

Next, we find the partial derivatives of both equations with respect to x and y and set them equal to zero to find the critical points.

Solving for x and y, we find that (0, ±9) are the critical points.

If the value is zero, the critical point is a saddle point.

[tex]\dfrac{4^{5/4} \cdot 4^{1/4}}{4^{1/2}}[/tex]

Numerator [tex]4^{5/4} \cdot 4^{1/4}[/tex] can be simplified to [tex]4^{5/4 + 1/4} = 4^{6/4} = 4^{3/2}\\\\[/tex]

The entire expression on parentheses becomes:

Determine the level of measurement of the variable. capacity of a backpack a.interval b.ordinal c.nominal d.ratio

Answers

Ratio: Because it has a meaningful zero point and allows for meaningful comparison of value differences, the volume of a backpack is a ratio level of measurement.

Ratio: A backpack's capacity is a ratio level of measurement because it has a meaningful zero point, or when an item (in this case, capacity) is absent, it has a value of zero. Additionally, it is possible to meaningfully compare value differences. As opposed to other levels of measurement like nominal or ordinal where the differences between two values may not be relevant, this means that differences in capacity between two backpacks may be compared properly.

For instance, the difference between two backpacks can be considered to be twice as great if one backpack has a capacity of 20 litres and the other has a capacity of 40 litres (20 liters). Ratio is the most suitable level of measurement for a backpack's capacity since other levels of measurement cannot account for this disparity.

The length of the other sides are 5cm and 12cm

How to determine the other sides

Let the legs of the right triangle be 'a' and 'b'. Let the hypotenuse be 'h'.

We have the formula for perimeter as;

Perimeter, p = a + b + h = 30 cm

p = a + b + 13 cm = 30 cm

a + b = 30 - 13 = 17 cm

a = 17 - b …………… (1)

Using the Pythagorean Theorem

a² + b² = h²

(17 - b)² + b² = 13² ................ From equation (1)

b² + 17² - 34b + b² = 169

2b² - 34b + 289 - 169 = 0

collect like terms

2b² - 34b + 120 = 0

b² - 17b + 60 = 0

solve the quadratic equation

b² - 12b - 5b + 60 = 0

b(b - 12) - 5(b - 12) = 0

Factor the like terms

(b - 12)(b - 5) = 0

b = {12, 5}

From equation (1), we have;

a = 17 - 12 = 5 cm, or a = 17 - 5 = 12 cm

Object A has a charge of 2 µc, and object B has a charge of 6 µc. Object B has a charge that is three times greater than object A.

Object A has a charge of 2 µc, and object B has a charge of 6 µc. To determine which statement is true, we need to compare the two charges. To do this, we can divide the charge of object B by the charge of object A. When we do this, the result is 3. This tells us that object B has a charge that is three times greater than object A. Therefore, we can conclude that the statement "Object B has a charge that is three times greater than object A" is true. Now that we know the statement is true, we can further explain why it is true. Object A has a charge of 2 µc, which is the smallest unit of charge and is equal to 10−6 coulombs. Object B has a charge of 6 µc, which is three times greater than the charge of object A. This means that the charge of object B is three times larger than the charge of object A. This is why the statement is true - because object B has a charge that is three times greater than object A.

Answers

The Logarithmic function is a mathematical operation that is used to determine the logarithm of a number.

The logarithm of a number x is the exponent to which a fixed number, the base, must be raised to produce x. The most common bases used are 10 and e. The formula for determining the logarithm of a number x base d is: log base d of x = (log base d of x)/(log base d of b).

For example, if we want to calculate the log base 10 of a number x, we would use the formula: log base 10 of x = (log base 10 of x)/(log base 10 of b). We can calculate the log base 10 of a number x by taking the logarithm of x and dividing it by the logarithm of the base, 10. The result will be the log base 10 of x.

For example, if we want to calculate the log base 10 of 25, we would calculate the logarithm of 25 and divide it by the logarithm of 10. The calculation would be: log base 10 of 25 = (log base 10 of 25)/(log base 10 of 10) = (1.3979)/(1) = 1.3979. This means that the log base 10 of 25 is 1.3979.

We may use the normal distribution and the Z-score to determine the likelihood that 100 randomly selected 1-gallon samples of standard unleaded gasoline will have an average of more than 4.3 ounces of the component. A value's Z-score indicates how many standard deviations away from the mean it is.

We must first get the average of 100 randomly chosen samples' mean and standard deviation. The average's mean will be 4 ounces, which is also the mean of the individual samples. The sample size is divided by the square root of the standard deviation to get the average standard deviation, which is 1.2/100 = 0.12 ounces.

Next, we calculate the Z-score for the value of 4.3 ounces:

Z = (4.3 - 4) / 0.12 = 0.83

Finally, we use a Z-score table or a normal distribution calculator to find the probability of finding an average in excess of 4.3 ounces. The result will be the area under the standard normal distribution curve to the right of 0.83.

There is a 79.72% chance of finding an average in excess of 4.3 ounces of the ingredient from 100 randomly inspected 1-gallon samples of regular unleaded gasoline.

gamblers often throw dice gently for low numbers and hard for high numbers. this most directly illustrates

Answers

This behavior most directly illustrates the concept of superstition in gambling. Gamblers may believe that throwing the dice a certain way will influence the outcome and affect the results they desire.

This is a common belief among gamblers, despite there being no scientific evidence to support it. In reality, the way the dice are thrown has no impact on the outcome, as the result is determined purely by chance and the laws of physics.

Nevertheless, the belief in superstition is widespread in gambling and can influence behavior and decision making.

Gamblers often pitch the dice gently for low numbers and hard for high numbers. This most directly adorned an illusion of control Regression towards the mean refers to the tendency for unusual events to be followed by more ordinary events.

int max; int min = 10; max = 17 − 4 / 10; max = max 6; min = max − min; system.out.println(max * 2); system.out.println(max min); system.out.println(max); system.out.println(min);

Answers

The output of the given code will be: 15, 2, 15, -5.

The given code declares two integer variables max and min, with min initialized to 10. The expression 17 - 4 / 10 is evaluated as 17 - 0, since integer division returns the floor value, which is 0 in this case.

The expression max = max - 6 then sets max to 17 - 0 - 6, which is equal to 11. The expression min = max - min then sets min to 11 - 10, which is equal to 1. Finally, the println statements print out the values of max * 2, max - min, max, and min. These values are 15, 2, 11, and 1, respectively.

why is this an inappropriate way to list classes in a frequency distribution for quantitative data? 1 up to 10 10 up to 12 12 up to 15 15 up to 25

Answers

Suppose the data on the quiz will be grouped into five classes. The width of the classes for a frequency distribution or histogram is closest to 15.

Total number of classes = 5

The data that represent scores on a pop quiz in a statistics section:

25 26 27 28 30 42 53 53 54 56 66 72 76 82 82 84 88 92 96 98

The maximum score from the data = 98

The minimum score from the data = 25

A frequency distribution for quantitative data = (Maximum Score - Minimum Score)/Total number of classes

A frequency distribution for quantitative data = (98 - 25)/5

A frequency distribution for quantitative data = 73/5

A frequency distribution for quantitative data = 14.5
