Answer:

[tex]\sqrt{122}[/tex] units

Step-by-step explanation:

To find the distance between points A(1,3) and D(2,-8), we can use the distance formula:

distance = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]

Plugging in the coordinates, we get:

distance = [tex]\sqrt{(2 - 1)^2 + (-8 - 3)^2}[/tex]

distance = [tex]\sqrt{1^2 + (-11)^2}[/tex]

distance = [tex]\sqrt{122}[/tex]

Therefore, the distance between points A(1,3) and D(2,-8) is [tex]\sqrt{122}[/tex] units.

Answer:

There were 8 bears

Step-by-step explanation:

Letting L = number of lions, T = number of tigers and B = number of bears

L : T = 3 : 2

We can rewrite this as
L/T = 3/2

Cross multiply:
L x 2 = 3 x T

Divide by 3 to get
T = 2/3 L

Since L = 9

T = 2/3 x 9 = 6

In the other ratio we have
T : B = 3 : 4 which we can write as
T/B = 3/4

Cross multiply to get

4T = 3B

B = 4/3 T

Since T = 6, B = 4/3 x 6 = 8

Check
L : T = 9 : 6 = 3: 2 (by dividing both sides of : by 3)
T : B = 6 : 8 = 3:4 (by dividing both sides of : by 2)

The compound interest on ₹20,000 for 3 years at 10% per annum compounded annually is ₹6,620.

To calculate the compound interest on a principal amount of ₹20,000 for 3 years at 10% per annum compounded annually, we can use the formula

A = P(1 + R/100)^n

Where,

A = final amount after n years

P = principal amount

R = annual interest rate

n = number of years

In this case, P = ₹20,000, R = 10%, and n = 3 years.

So, applying the formula

A = 20000(1 + 10/100)^3

= 20000(1.1)^3

= 20000(1.331)

= ₹26,620

The final amount after 3 years is ₹26,620. Therefore, the compound interest is

Compound Interest = Final Amount - Principal Amount

= ₹26,620 - ₹20,000

Answer:

Step-by-step explanation:

To solve the initial-value problem y''' − 2y'' + y' = 2 − 24ex + 40e5x, y(0) = 1/2, y'(0) = 5/2, y''(0) = −11/2, we first find the characteristic equation by assuming that y = e^(rt):

r^3 - 2r^2 + r = 0

r(r^2 - 2r + 1) = 0

r(r-1)^2 = 0

r = 0, 1, 1

Therefore, the general solution to the homogeneous equation y''' − 2y'' + y' = 0 is:

y_h = c1 + c2e^x + c3xe^x

To find the particular solution to the non-homogeneous equation y''' − 2y'' + y' = 2 − 24ex + 40e5x, we guess a particular solution of the form:

y_p = Ax^2e^5x + Be^x

y_p' = (2Ax + 5Ax^2)e^5x + Be^x

y_p'' = (10Ax^2 + 4Ax + 25Ax^2)e^5x + Be^x

y_p''' = (70Ax^2 + 60Ax + 10A + 25Ax^2)e^5x + Be^x

Substituting these expressions into the original equation, we get:

(70Ax^2 + 60Ax + 10A + 25Ax^2)e^5x + Be^x − 2[(10Ax^2 + 4Ax + 25Ax^2)e^5x + Be^x] + [(2Ax + 5Ax^2)e^5x + Be^x] = 2 − 24ex + 40e5x

Simplifying, we get:

(45Ax^2 + 2Ax − 2)e^5x + Be^x = 2 − 24ex + 40e5x

Equating the coefficients of the like terms on both sides, we get:

45A = 40

2A − 2 = 0

B = 2

Therefore, the particular solution is:

y_p = 8/9 x^2e^5x + 2e^x

The general solution to the non-homogeneous equation is therefore:

y = c1 + c2e^x + c3xe^x + 8/9 x^2e^5x + 2e^x

Using the initial conditions y(0) = 1/2, y'(0) = 5/2, y''(0) = −11/2, we get:

c1 + c2 + 2 = 1/2

c2 + 2c3 + 5/2 = 5/2

2c2 + 10/9 + 10 = -11/2

Solving this system of equations, we get:

c1 = 1/9

c2 = -25/18

c3 = 0

Therefore, the solution to the initial-value problem y''' − 2y'' + y' = 2 − 24ex + 40e5x, y(0) = 1/2, y'(0) = 5/2, y''(0) = −11/2 is:

y = 1/9 - 25/18e^x + 8/9

The range of values for t where both particles are moving in the same direction along the straight line is 1 < t < 2 or t > 2.

A function's derivative is a gauge of how quickly the function is altering at a specific moment. It is that point's tangent line's slope to the function. The limit of the difference quotient as the change in x becomes closer to zero is the definition of the derivative, which is represented by the symbols f'(x) or dy/dx.

Given the displacement of the two particles, the velocity of the given particles can be calculated using the derivative of the distance as follows:

s=t³-4t²+5t

s'(t) = 3t² - 8t + 5 and,

x=t²-4t+4

x'(t) = 2t - 4

Case 1: Both velocities are positive

s'(t) > 0 and x'(t) > 0

3t² - 8t + 5 > 0 and 2t - 4 > 0

t < 1 or t > 2

Case 2: Both velocities are negative

s'(t) < 0 and x'(t) < 0

3t² - 8t + 5 < 0 and 2t - 4 < 0

1 < t < 2

Therefore, the range of values for t where both particles are moving in the same direction along the straight line is 1 < t < 2 or t > 2.

The length of the third side of a triangle provided if the first two sides measure 10 and 12 is 2 < c < 22.

Three sides and three angles make up each triangle. These triangle sides are straight line segments that meet at each of the triangle's vertices to produce a closed three-sided shape. Each side of a right-angled triangle is given a name. The hypotenuse of a right-angled triangle is its longest side, the base is its lowest side, and the perpendicular, which stands next to the right angle, is its standing line.

Each valid triangle has a side length that is smaller than the sum of the other two.

Answer:

This table represents a linear relationship that is also proportional:

x 0 1 2

y −4 0 4

Answer:

The second table represents a linear relationship that is also proportional.

To check if a relationship is proportional, we need to see if the ratio of y to x is constant for all values of x and y. In other words, if we divide any y value by its corresponding x value, we should get the same number for all values.

Let's check the ratio for each table:

Ratio for the first table:

-3/2 = -1.5

0/3 = 0

3/4 = 0.75

The ratio is not constant, so this relationship is not proportional.

Ratio for the second table:

-2/4 = -0.5

-1/2 = -0.5

0/0 = undefined

The ratio is constant (-0.5), so this relationship is proportional.

Ratio for the third table:

0/(-2) = 0

1/1 = 1

2/4 = 0.5

The ratio is not constant, so this relationship is not proportional.

Ratio for the fourth table:

-4/0 = undefined

0/1 = 0

4/2 = 2

The ratio is not constant, so this relationship is not proportional.

Therefore, the second table is the only one that represents a linear relationship that is also proportional.

n(H ∩ G) = n(H) + n(G) - n(H U G)

where n (H U G) represents the number of students who study either History or Government or both.

We know that n(H) = 2x and n(G) = 3x. Also, n(U) = 54, which means the total number of students is 54. Therefore, we can write:

n (H U G) = n(H) + n(G) - n (H ∩ G)

54 = 2x + 3x - x

54 = 4x

x = 13.5

Since x must be a whole number, we can round it up to 14. Therefore, n (H ∩ G) = x = 14.

ii. The number of students who study only one subject can be found by subtracting n (H ∩ G) from n(H) and n(G) respectively, and then adding the number of students who study neither History nor Government.

n(H-only) = n(H) - n (H ∩ G) = 2x - x = x = 14

n(G-only) = n(G) - n (H ∩ G) = 3x - x = 2x = 28

Coordinates are a set of values that locate the position of a point in space. In mathematics, coordinates are used to represent the position of points on a plane or in space, using a set of numerical values that correspond to the distance along each axis from an origin point. In two-dimensional Cartesian coordinate systems, for example, a point is represented by two numbers (x, y) that indicate its position relative to the x and y axes. In three-dimensional Cartesian coordinate systems, a point is represented by three numbers (x, y, z) that indicate its position relative to the x, y, and z axes.

Here,

The average rate of change between the points (3,9) and (5,15) is the slope of the line passing through those two points. We can use the slope formula:

slope = (y2 - y1) / (x2 - x1)

The MAD of the portions of popped balloons is 0.046.

The Mean Absolute Deviation (MAD) is a measure of the average distance between each data point and the mean of the data set. It gives an idea of how spread out the data is around the mean.

To find the mean, median, and MAD (mean absolute deviation) of the given data, we first need to find the average value of the portions of popped balloons.

Mean = (16% + 2/25 + 0.06 + 1/50 + 0.12 + 0.04) / 6

Mean = 0.0975

Therefore, the mean of the portions of popped balloons is 0.0975.

To find the median, we need to first arrange the portions in ascending order:

0.04, 0.06, 1/50, 2/25, 0.12, 16%

Median = (1/50 + 0.06) / 2

Median = 0.035

Therefore, the median of the portions of popped balloons is 0.035.

To find the MAD, we first need to find the absolute deviations of each portion from the mean. We can do this by subtracting the mean from each portion and taking the absolute value:

|0.16 - 0.0975| = 0.0625

|2/25 - 0.0975| = 0.0525

|0.06 - 0.0975| = 0.0375

|1/50 - 0.0975| = 0.0475

|0.12 - 0.0975| = 0.0225

|0.04 - 0.0975| = 0.0575

The MAD is the average of these absolute deviations:

MAD = (0.0625 + 0.0525 + 0.0375 + 0.0475 + 0.0225 + 0.0575) / 6

MAD = 0.046

Performing a simulation with 100 trials is a common technique used to assess the impact of chance variation on the results of an experiment or study. The simulation can help you understand how likely it is to see certain results due to chance variation alone, rather than any underlying difference in proportions.

To perform this simulation, you would first need to define the two proportions that you want to compare. For example, you might want to compare the proportion of people who prefer brand A to brand B in a survey.

Next, you would randomly assign each trial to either brand A or brand B based on the defined proportions. For example, if the proportion of people who prefer brand A is 0.6, you would assign 60 out of the 100 trials to brand A and 40 trials to brand B.

After assigning each trial, you would then calculate the difference in proportions between the two groups. This would give you a distribution of differences that you would expect to see due to chance variation alone.

If the observed difference falls within the range of differences expected due to chance variation, you can conclude that the difference in proportions you observed is not statistically significant and may be due to chance.

However, if the observed difference is larger than what you would expect to see due to chance variation, you can conclude that the difference is statistically significant and likely due to an underlying difference in proportions.

To calculate the population variance

[tex]= [(-4)^{2} + (-2)^{2} + 6^{2} ]/3[/tex]

[tex]= (16 + 4 + 36)/3[/tex]

[tex]= 56/3[/tex]

[tex]= 18.67[/tex] (rounded to two decimal places)

Therefore, the population variance is approximately [tex]18.67[/tex].

After answering the provided question, we can conclude that  This expression process frequently results in bolt diameters that are normally distributed, with minor random variations around the target diameter.

In mathematics, an expression is a collection of symbols, digits, and companies that portray a statistical correlation or formula. An expression can be a single number, a mutable, or a combination of both of them. Addition, subtraction, proliferation, division, and exponentiation are examples of mathematical operators.  Expressions are used extensively in mathematics, including arithmetic, calculus, and geometry. They are used in mathematical formula representation, equation solution, and mathematical relationship simplification.

a) Because of the central limit theorem, the volume of soft drinks in cans is likely to follow a normal distribution. Because soft drink manufacturers typically produce a large number of cans filled with the same volume of liquid, the sample size is large.

b) The diameter of bolts immediately after manufacture is also likely to be distributed normally. Bolt manufacturing typically involves a large number of measurements and adjustments to ensure that the bolts are manufactured to exact specifications. This process frequently results in bolt diameters that are normally distributed, with minor random variations around the target diameter.
