What would result from slicing a rectangular pyramid perpendicular to the base?

Answer:

9,-5

Step-by-step explanation:

If you're looking for the solution of systems of linear equations, the answer would be (9,-5).

The slopes of GH, HI, IJ, and JG include the following:

In Mathematics and Geometry, the slope of any straight line can be determined by using the following mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = rise/run

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

By substituting the given data points into the formula for the slope of a line, we have the following;

Slope GH = (-3 + 9)/(-4 + 7)

Slope GH = 6/3

Slope GH = 2.

Slope HI = (5 + 3)/(-6 + 4)

Slope HI = -8/2

Slope HI = -4.

Slope IJ = (-1 - 5)/(-9 + 6)

Slope IJ = -6/-3

Slope IJ = 2.

Slope JG = (-9 + 1)/(-7 + 9)

Slope JG = -8/2

Slope JG = -4.

The association between the amount of money a person spends on bills per month and the amount of money the person has available to spend on entertainment can vary greatly depending on individual circumstances.

For some people, their bills may take up a significant portion of their income, leaving them with very little discretionary spending. Others may have lower bills and more income, allowing them to spend more on entertainment.
It's important to note that there may also be other factors at play, such as a person's financial priorities and habits. For example, someone may choose to spend more on bills in order to pay off debt or save for the future, even if it means having less money for entertainment. On the other hand, someone else may prioritize entertainment spending and cut back on bills in order to afford it.
Overall, while there may be some correlation between bill spending and available entertainment funds, the relationship is complex and highly individualized. It's important for each person to assess their own financial situation and priorities in order to determine the best way to allocate their funds.

a) The probability that the individual has an IQ greater than 122 is 0.0668 (rounded to four decimal places).Explanation:Given that the IQ is normally distributed with a mean of 100 and standard deviation of 15. We have to find the probability that the individual has an IQ greater than 122. Let X be the IQ of an individual. So, we have:X ~ N(100, 15²)

Let Z be the standard normal random variable.So, z = (X - µ) / σ = (122 - 100) / 15 = 1.47Now, P(X > 122) = P(Z > 1.47)From the standard normal table, we can find that P(Z > 1.47) = 0.0668Therefore, the probability that the individual has an IQ greater than 122 is 0.0668 (rounded to four decimal places).b) The minimum IQ you would need to qualify for membership is 130 (rounded to the nearest whole number).Explanation:Given that MENSA is an organization whose members have IQs in the top 4%.Let X be the IQ of an individual.

the length of the hypotenuse for a non-right triangle can be find by using the formula c = √(a² + b² - 2ab*cos(C))

To find the hypotenuse of a non-right triangle, you need to use the law of cosines. The law of cosines relates the lengths of the sides of a triangle to the cosine of one of its angles. The formula is as follows:

c² = a² + b² - 2ab*cos(C)

Where:

- c is the length of the hypotenuse

- a and b are the lengths of the other two sides

- C is the angle opposite to side c

To find the hypotenuse, you need to know the lengths of the other two sides and the measure of the angle opposite the hypotenuse. Once you have these values, plug them into the formula and solve for c by taking the square root of both sides.

c = √(a² + b² - 2ab*cos(C))

The average value fave of the function f(x) = x on the interval [0, 16] is 8. This means that if we were to draw the graph of f(x) on this interval, the line y = 8 would be the horizontal line .

To find the average value fave of the function f on the given interval [0, 16], we need to use the formula:

fave = (1/(b-a)) * ∫(a to b) f(x) dx

Here, a = 0 and b = 16, and f(x) = x. So, we have:

fave = (1/(16-0)) * ∫(0 to 16) x dx

= (1/16) * [x^2/2] (from 0 to 16)

= (1/16) * [(16^2)/2 - (0^2)/2]

= (1/16) * [128]

= 8

Therefore, the average value fave of the function f(x) = x on the interval [0, 16] is 8. This means that if we were to draw the graph of f(x) on this interval, the line y = 8 would be the horizontal line that divides the area above the graph from the area below the graph into two equal parts.

Step-by-step explanation:

The gradient of the function \(\(f\)\) at the point \(\((-1, -3)\)\) is:

\(\[\nabla f(-1, -3) = \left(-3e^{-3} \sin(12), 4e^{-3} \cos(12)\right)\]\)

To find the gradient of the function \(\( f(x, y) = e^{3x} \sin(4y) \)\) at the point \(\((-1, -3)\)\), we need to compute the partial derivatives with respect to \(\(x\) and \(y\)\) and evaluate them at that point.

The gradient of a function is given by:

\(\[\nabla f(x, y) = \left(\frac{{\partial f}}{{\partial x}}, \frac{{\partial f}}{{\partial y}}\right)\]\)

Let's calculate the partial derivatives:

\(\[\frac{{\partial f}}{{\partial x}} = \frac{{\partial}}{{\partial x}}\left(e^{3x} \sin(4y)\right) = 3e^{3x} \sin(4y)\]\)

\(\[\frac{{\partial f}}{{\partial y}} = \frac{{\partial}}{{\partial y}}\left(e^{3x} \sin(4y)\right) = 4e^{3x} \cos(4y)\]\)

Now, we can evaluate these derivatives at the point \(\((-1, -3)\):\)

\(\[\frac{{\partial f}}{{\partial x}}\Bigr|_{(-1, -3)} = 3e^{3(-1)} \sin(4(-3)) = 3e^{-3} \sin(-12)\]\)

\(\[\frac{{\partial f}}{{\partial y}}\Bigr|_{(-1, -3)} = 4e^{3(-1)} \cos(4(-3)) = 4e^{-3} \cos(-12)\]\)

Simplifying further:

\(\[\frac{{\partial f}}{{\partial x}}\Bigr|_{(-1, -3)} = 3e^{-3} \sin(-12) = -3e^{-3} \sin(12)\]\)

\(\[\frac{{\partial f}}{{\partial y}}\Bigr|_{(-1, -3)} = 4e^{-3} \cos(-12) = 4e^{-3} \cos(12)\]\)

Therefore, the gradient of the function \(\(f\)\) at the point \(\((-1, -3)\)\) is:

\(\[\nabla f(-1, -3) = \left(-3e^{-3} \sin(12), 4e^{-3} \cos(12)\right)\]\)

Answer:

\(T(2,4) and U(11,13)\)

Step-by-step explanation:

The three angles above the bottom line are supplementary, so they add up to 180° in measure:

2x° + 90° + x° = 180°

3x° + 90° = 180°

3x° = 90°

x = 30

The angles with measure x° and 2y° are congruent, since they form a pair of interior angles that alternate with respect to the transversal (in this case, this is the ray that starts from the bottom line and point up and to the right, and passes through the parallel upper line). So

2y° = x°

2y° = 30°

y = 15

Below the upper line, the two angles 2y° and z° are supplementary, so

2y° + z° = 180°

30° + z° = 180°

z = 150

So all of the population of the female is 51% and the ones who rent is only 10%. the probability is 19%

The solution is, 0.20 is the probability that the person rents action-movie DVDs, given that the person is female.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

given that,

Data:

A: the adult is a male, P(A) = 0.49

B: the adult rent action-movie DVDs

C: the adult is a female,  P(C) = 1 - P(A) = 1 - 0.49 = 0.51  

24% of the adults are male and rent action-movie DVDs, then P(A ∩ B) = 0.24

10% of the adults are female and rent action-movie DVDs, then P(C ∩ B) = 0.10

The conditional probability of B (the adult rents action-movie DVDs) given C (the adult is female) is computed as follows:

P(B|C) = P(C ∩ B)/P(C)

          = 0.1/0.51

Given y= x1/(x1+x2)  we need to find the total differential of y.It is given that, y= x1/(x1+x2)Let us assume, x1 = x1+Δx1, x2 = x2+Δx2. On substituting these values, we get + dy = (x1 + Δx1)/ (x1 + Δx1 + x2 + Δx2)We know that dy = y - (x1 + Δx1)/ (x1 + Δx1 + x2 + Δx2)

On further simplification, we get,dy = (Δx1(x2+Δx2))/(x1+Δx1+x2+Δx2)²-(Δx1x2)/((x1+Δx1+x2+Δx2)²)Since Δx1 and Δx2 are very small, we can neglect their squares and products, i.e., Δx1², Δx2², and Δx1.Δx2

Hence the total differential of y= x1/(x1+x2) is given by dy = (-x1x2/(x1+x2)²) dx1 + (x1²/(x1+x2)²) dx2. Note: x1 and x2 are independent variables.

Therefore, dx1 and dx2 are their differentials.Given y=2x1x2 /(x1+x2) Let us assume, x1 = x1+Δx1, x2 = x2+Δx2. On substituting these values, we gety + dy = 2(x1 + Δx1)(x2 + Δx2)/ (x1 + Δx1 + x2 + Δx2)On simplifying, we gety + dy = (2x1x2+2x1Δx2+2x2Δx1+2Δx1Δx2)/(x1+Δx1+x2+Δx2)

Since Δx1 and Δx2 are very small, we can neglect their squares and products, i.e., Δx1², Δx2², and Δx1.Δx2
