Answer:

x = 5 , y = -1

Step-by-step explanation:

x + 2y = 3........(equation 1)

x - y = 6..........(equation 2)

make x the subject of the formula in (equation 1)

x = 3 - 2y

substitute for x in (equation 2)

3x - y = 6

(3- 2y) - y = 6

3 - 2y - y = 6

3 - 3y = 6

-3y = 6 - 3

\( \frac{ - 3y}{ - 3} = \frac{3}{ - 3} \)

\(y = - 1\)

substitute for y in (equation 1)

x = 3 - 2y

\( \times = 3 - 2( - 1)\)

x = 5

Answer:

Uhhh I'll try my best.

The answer to your question is

I’ll do x.

x+2y-2y = 3-2y

(Simplify) x = 3-2y

x-y+y = 6+y

(Simplify) x = 6+y

3-2y = 6+y

3-2y-6 = 6+y+2y

Relationship:

Complementary angles add up to 90 degrees

JKL + MNP = 90

Solve for x:

(2x - 3) + (5x + 2) = 90

7x - 1 = 90

7x = 91

x = 13

Solve for JKL:

JKL = 2x - 3

JKL = 2(13) - 3

JKL = 23 degrees

Solve for MNP:

MNP = 5x + 2

MNP = 5(13) + 2

MNP = 67

The probability that the red die shows a three and the blue die shows a number greater than three is 1/12

From the question, we have the following parameters that can be used in our computation:

Red die

Blue die

The sample space of a die is

{1, 2, 3, 4, 5, 6}

using the above as a guide, we have the following:

P(3) = 1/6

P(Greater than 3) = 1/2

So, we have

P = 1/2 * 1/6

Evaluate

P = 1/12

To calculate the uncertainty and percent uncertainty of the dependent quantity in terms of the given measured quantities, we can apply error propagation using the provided formula: δA = (∂x/∂A)^2(δx)^3 + (∂y/∂A)^2(δy)^2 + (∂z/∂A)^2(δz)^2 + ...

1. For z = me^y, where y is the measured quantity with uncertainty Δy and m is a constant, the uncertainty ΔA and percent uncertainty ΔA% of A can be calculated using the error propagation formula, considering the partial derivatives (∂x/∂A, ∂y/∂A, ∂z/∂A, ...) specific to this equation.

2. In the case of P = 4L + 3W, with L and W as measured quantities with uncertainties ΔL and ΔW respectively, the uncertainty ΔA and percent uncertainty ΔA% of A can be determined using error propagation, taking into account the partial derivatives (∂x/∂A, ∂y/∂A, ∂z/∂A, ...) based on the given equation.

3. Similarly, for the equation z = 3x - 5yx, with Δx and Δy being the uncertainties associated with x and y respectively, the uncertainty ΔA and percent uncertainty ΔA% of A can be calculated using error propagation and the specific partial derivatives (∂x/∂A, ∂y/∂A, ∂z/∂A, ...).

4. In the scenario I = A/r^2, where r is a measured quantity with uncertainty Δr and A is a constant, the uncertainty ΔA and percent uncertainty ΔA% of A can be determined using the provided error propagation formula and the relevant partial derivatives.

5. For N = 0.5rpR^4h, with R and h being measured quantities, the uncertainty ΔA and percent uncertainty ΔA% of A can be calculated using error propagation and the specific partial derivatives (∂x/∂A, ∂y/∂A, ∂z/∂A, ...) based on the given equation.

6. In the equation A = 2LW + 2WH + 2H, where L, W, and H are measured quantities with uncertainties ΔL, ΔW, and ΔH respectively, the uncertainty ΔA and percent uncertainty ΔA% of A can be determined using error propagation and the appropriate partial derivatives.

7. Finally, for the scenario involving M1, M2, and d as measured quantities with uncertainties ΔM1, ΔM2, and Δd respectively, the uncertainty ΔA and percent uncertainty ΔA% of A can be calculated using the error propagation formula and the relevant partial derivatives.

By applying error propagation and the provided formula to each scenario, we can calculate the uncertainty and percent uncertainty of the dependent quantity A in terms of the measured quantities and their respective uncertainties.

Answer:

Ann’s work is correct

Step-by-step explanation:

The coordinates of Casper which lies exactly in the middle of Denton and Beacon are (-4, -1).

Coordinates are defined as the set of points in a coordinate plane or space, which describes the position of that point in that plane or space.

In a coordinate plane, the midpoint of two points (x₁, y₁) and (x₂, y₂) is the point (x, y) such that their measures are,

x = (x₁ + x₂) / 2

y = (y₁ + y₂) / 2

First, we can write the given measures.

Coordinates of Albion = (5, 5)

Coordinates of Denton = (-7, -3)

Given that, Beacon is lying exactly in the middle of Albion and Denton.

Let the coordinates of Beacon be (x, y).

Using the formula above,

x coordinate of Beacon = (5 + -7) / 2 = -1

y coordinate of Beacon = (5 + -3) / 2 = 1

Coordinates of Beacon are thus (-1, 1).

Casper is lying exactly in the middle of Denton(-7, -3) and Beacon (-1, 1).

Let (x' , y') be the coordinates of Casper.

Using the same formula,

x' = (-7 + -1) / 2 = -4

y' = (-3 + 1) / 2 = -1

Hence the coordinates of Casper are (-4, -1).

Answer:

m = 5/2

Step-by-step explanation:

The slope is rise/run or (y2 - y1) / (x2 - x1)

The y decrease by 5, and the x decrease by 2, so the slope is

-5/-2 = 5/2

So, m = 5/2

Hello!

We are going to find the slope of the line that passes through our given points: (8, 9) and (6, 4).

To find the slope, we will use the slope formula, which states:

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

Our variables in the formula are given by the coordinates that we know.

(x1, y1)

(8, 9)

And

(x2, y2)

(6, 4)

Solve:

Plug in the coordinates into the correct variable and solve:

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

m = (4 - 9)/(6 - 8)

m = -5/(6 - 8)

m = -5/-2

Simplify:

m = 5/2

Therefore, the slope of the line is 5/2.

Answer:

(x, y) = ( 5, 6)

(x, y) = ( - 1, 0)

Step-by-step explanation:

\( \begin{cases} y + x^2 - 5x = 6\\\\ y - x = 1\implies y = x + 1\end{cases} \)

Plug \( y = x +1 \) in the equation \( y + x^2 - 5x = 6\) we find:

\( x + 1 + x^2 - 5x = 6\)

\( x^2 - 4x - 5=0\)

\( x^2 - 5x +x- 5=0\)

\( x(x - 5) +1(x- 5)=0\)

\( (x - 5) (x+1)=0\)

\( (x - 5) =0, \: (x+1)=0\)

\( x =5, \: x=-1\)

\( When \:x =5 \implies y =5+1=6 \)

(x, y) = ( 5, 6)

\( When \:x =-1 \implies y =-1+1=0 \)

The required probability is P(A and C) is 0.2 which is represented in the tree diagram.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

The given tree diagram represents an experiment consisting of two trials.

The tree diagram represents an experiment consisting of two trials. In this case, the probability of event A and event C occurring is represented by the intersection of branches A and C in the tree diagram.

This probability can be calculated by multiplying the probability of each individual event together.

Let there be a point P(2, 3) on the cartesian plane. The image of this point in the line y=−x will lie on a line that is perpendicular to this line and the distance of this point from y=−x will be equal to the distance of the image from this line.

Let Q be the image of p and let the co-ordinate of Q be (h, k)

The slope of line y=−x is −1

Line joining P, Q will be perpendicular to y=−x so, its slope =1.

Let the equation of the line be y=x+c since this passes through points (2,3)

To find the inverse of a number modulo another number, we need to find a number that, when multiplied by the original number, gives a remainder of 1 when divided by the modulus.

(a) To verify that 50 is the inverse of 5 modulo 83, we can calculate 5 * 50 ≡ 250 ≡ 1 (mod 83). Similarly, for 12 as the inverse of 7 modulo 83, we have 7 * 12 ≡ 84 ≡ 1 (mod 83). Therefore, both 50 and 12 are inverses of their respective numbers modulo 83.

(b) To find the inverse of 49 modulo 83, we need to find a number x such that 49 * x ≡ 1 (mod 83). We can use trial and error or utilize the extended Euclidean algorithm to calculate the inverse. In this case, we find that the inverse of 49 modulo 83 is 32 since 49 * 32 ≡ 1568 ≡ 1 (mod 83).

The professor uses sample data from the population to determine the average age. Anytime inferential statistics or statistical inference is used to make inferences from samples.

Instead of gathering data from the entire institution, the professor took age samples from a class and used those data to draw conclusions about the entire university.

Descriptive statistics in statistics help you describe the facts, whereas inferential statistics assist you in drawing conclusions from the data.

Data from the sample are used in inferential statistics, which allows you to generalise about the population.

Inference generally refers to "guessing," which involves drawing conclusions about something.
