How do you use the mean absolute deviation to compare data sets?

By using Heron's formula, it can be calculated that the material used for the entire kite is 48 square inches.

Heron's formula is used for finding the area of a triangle in terms of the lengths of its sides.

Area = √s(s - a)(s - b)(s - c) where:

s = half the perimeter = (a + b + c)/2

a,b,c = sides of the triangle

A kite is made up of two isosceles triangles, ΔKIT and ΔKET.

Area ΔKIT=  17 square inches

KI = 6 in

ET = 8 in

KT = 10 in

Start by calculating the perimeter of ΔKET:

perimeter = KE + ET + TK

                = 8 + 8 + 10

                = 26 in

The area of ΔKET can be obtained using Heron's formula:

Area = √s(s - a)(s - b)(s - c)

        = √ 13 (13 - KE) (13 - ET) (13 - TK)

        = √ 13 (13 - 8) (13 - 8) (13 - 10)

        = √ 13 · 5 · 5 · 3

        = √ 975

        = 31.22 square inches

Since the quadrilateral KITE is composed of ΔKIT and ΔKET, then its area is equal to the total area of the triangles:

Area KITE = Area ΔKIT + Area ΔKET

                 = 17 + 31.22

                 = 48.22

                 ≈ 48 square inches

Thus, the material used for the entire kite is 48 square inches.

The solution to this system of equations is x = -6, y = 9, and z = 5.

To solve this system of equations using row operations or elementary matrices, we can first start by subtracting 4x from both sides of the first equation. This leaves us with 3x - 3x = -6. Since the x terms cancel out, this equation is now true for any value of x. We can then use this equation to substitute -6 for the x terms in the other two equations. In the second equation, we have 5y - 2y - 6 = -16. We can then subtract 5y from both sides of the equation to get -2y - 6 = -16. Dividing both sides by -2 gives us y = 9. The third equation is now 3y - 3z - 4z - 4z = -6. We can then subtract 3y from both sides of the equation to get -3z - 4z = -15. We can then divide both sides of the equation by -3 to get z = 5. Therefore, the solution to this  system of equations  is x = -6, y = 9, and z = 5.

The function u(x, y) = x^(1/3) * y^(2/3) is a multivariable function.

We have the function u(x,y) = x1/3y2/3. The function u(x, y) = x^(1/3) * y^(2/3) is a multivariable function, where x and y are variables and x^(1/3) and y^(2/3) are exponents. It describes the relationship between the inputs x and y and the output u. To solve for u, you would need to substitute specific values for x and y and evaluate the expression.

However, it is not possible to solve this function in the traditional sense because it is not a linear equation with a single solution. Instead, it is a surface in a three-dimensional space, where x and y are the two axes and u is the height. The value of u at any given point on the surface can be found by evaluating the function with the corresponding x and y values.

Therefore, The function u(x, y) = x^(1/3) * y^(2/3) is a multivariable function

The required value of integration of given function is 82.

To evaluate the integral  we need to find the anti-derivative of F(x) and then evaluate it at the limits of integration.

Since F(x) = 8 for x < 8 and F(x) = x for x ≥ 8, we can split the integral into two parts, one from 0 to 8 and another from 8 to 10

Approximately 84% of scores fall between the mean and z = -1 for normally distributed scores.

In a normal distribution, approximately 68% of the scores fall within one standard deviation of the mean, both above and below. Z-scores are used to describe the location of a score relative to the mean, in terms of standard deviations.

A z-score of -1 indicates that a score is 1 standard deviation below the mean. So, if we consider all the scores that are 1 standard deviation below the mean or closer to the mean, then we would have a total of 68% of the scores, which includes the mean.

And, if we consider only the scores that are between the mean and 1 standard deviation below the mean, then we would have 84% of the scores. Hence, approximately 84% of scores would fall between the mean and z = -1 for normally distributed scores.

For this problem, we have the final population P, the starting population A, and the time passed t.

We still need to determine the value of the growth factor k.

This can be done using the information for the years 1995 and 2001.

In this case, A will be 23 million (the population in 1995), P will be 25 million (the population in 2001), and t will be 6 years (the number of years between 1995 and2001):

One method is to substitute the value of x from one equation into the other equation, solve for y, then use the value of y to find x.

Starting with the second equation: 5x + 2y = 48

Solve for y: y = (48 - 5x) / 2

Now substitute this expression for y into the first equation:

-5x - 12((48 - 5x) / 2) = -8

-5x - 6(48 - 5x) = -8

-5x - 288 + 30x = -8

To determine whether the sequence converges or diverges, we can use the Squeeze Theorem.

We can see that

4/ n+5n^2 < = An <= 4+3n^2/ n+5n^2

As n tends to infinity,  4/ n+5n^2  tends to 0 and 4+3n^2/ n+5n^2 tends to  4/5n^2 which also tends to 0.

So by the Squeeze Theorem, we can say that An tends to 0 as n tends to infinity. Hence the limit of the sequence is Lim n-> An = 0

We can also see that the numerator of An is a constant and the denominator is a polynomial with degree 2. Since the denominator's degree is greater than the numerator, the limit will be zero as n -> infinity.

Therefore, the sequence converges to 0.

What is orbital radius and periods in circular motion?

Planetary bodies circle the Sun according to Kepler's three laws. They explain how planets orbit the Sun in elliptical fashion, how they traverse the same amount of space in a given length of time regardless of where they are in their orbit, and how their orbital periods are related to the size of their orbits (its semi-major axis).

An object's orbital radius is the typical distance it travels around a bigger object. An illustration would be that the Sun and Earth are typically 150 million kilometres apart. The orbital radius is also this.

Let the mass of the planet be m and the mass of the star be M.

r = radius of ordit

v = speed

We know that

gravitational attraction = centripital force

By applying standard equation of a circle concept, it can be concluded that the equation that defines the circle is  (x + 4)² + (y - 3)² = 50.

Circle is a collection of points on a plane line that are all the same distance (the radius) from a given point (the center).

Standard equation of a circle can be written as:

(x - h)² + (y - k)² = r²   , where:

(h,k) = center of the circle

r = radius

We know that the radius of the circle has endpoints (-4,3) and (1,-2), which means that one of these points is the center of the circle.

Since we know that its center is in the second quadrant, we can conclude that (-4,3) is the center.

Now we can substitute these values into the equation:

   (x - h)² + (y - k)² = r²

(1 - (-4))² + (-2 - 3)² = r²

              5² + (-5)² = r²

                25 + 25 = r²

                        50 = r²

As we know the r, now we can have the standard equation of the circle:

   (x - h)² + (y - k)² = r²

(x - (-4))² + (y - 3)² = 50

 (x + 4)² + (y - 3)² = 50

x + y ≤ 20

15x + 25y ≥ 375

To maximize the number of hours the student works at the doctor's office while still earning at least $375, we must solve this system of inequalities. To do this, we can subtract 15x from both sides of the second inequality to isolate y:

25y ≥ 375 - 15x

We can then divide both sides of this equation by 25 to solve for y:

y ≥ (375 - 15x) / 25

We can then substitute this expression for y in the first inequality to solve for x:

x + (375 - 15x) / 25 ≤ 20

We can then rearrange and solve this equation for x:

15x + 375 ≤ 500

15x ≤ 125

x ≤ 8.33.

Since the student can only work a whole number of hours, the student should work 8 hours at the doctor's office each week. The student should then tutor for 12 hours each week in order to earn at least $375.
