Table C represents a linear relationship that is also proportional. This is because the ratio of the output (y) to the input (x) is always constant, which is a characteristic of proportional relationships.

What is a linear equation?

A linear equation is an algebraic equation that represents a straight line on a graph. In general, a linear equation takes the form:

y = mx + b

A linear relationship between two variables, x and y, is one in which the change in y is directly proportional to the change in x. This means that for any change in x, there is a corresponding change in y that can be expressed as a constant multiple of x.

For example, if we have a linear relationship y = mx + b, where m is the slope of the line and b is the y-intercept, then if we increase x by 1 unit, y will increase by m units. This relationship holds true for all values of x and y along the line.

A proportional relationship, on the other hand, is a special case of a linear relationship in which the ratio of y to x is always the same constant. This means that if we increase x by 1 unit, y will increase by a constant multiple of x. In other words, the relationship between x and y is one of scaling, where the size of y is always a fixed multiple of the size of x.

Therefore, Table C represents a linear relationship that is also proportional. This is because the ratio of the output (y) to the input (x) is always constant, which is a characteristic of proportional relationships.

The perimeter of a figure

Answer:

Step-by-step explanation:

True.

Answer:

False

Step-by-step explanation:

Answer:

2 pi

Step-by-step explanation:

The radius is 2

The area of a circle is

A = pi r^2

We have 1/2 of a circle so

1/2 A = 1/2 pi r^2

         =1/2 pi ( 2)^2

         =1/2 pi *4

      = 2 pi

Let's calculate the products and check if they indeed have the same value:

Product of 32 and 46:

32 * 46 = 1,472

Reverse the digits of 23 and 64:

23 * 64 = 1,472

As you mentioned, the products are the same. This phenomenon is not unique to this particular pair of numbers. In fact, it occurs with any pair of two-digit numbers whose digits, when reversed, are the same as the product of the original numbers.

To find two other pairs of two-digit numbers that have this property, we can explore a few examples:

Product of 13 and 62:

13 * 62 = 806

Reversed digits: 31 * 26 = 806

Product of 17 and 83:

17 * 83 = 1,411

Reversed digits: 71 * 38 = 1,411

As for determining if a given pair of two-digit numbers will have this property without actually performing the multiplication, there is a simple rule. For any pair of two-digit numbers (AB and CD), if the sum of A and D equals the sum of B and C, then the products of the original and reversed digits will be the same.

For example, let's consider the pair 25 and 79:

A = 2, B = 5, C = 7, D = 9

The sum of A and D is 2 + 9 = 11, and the sum of B and C is 5 + 7 = 12. Since the sums are not equal (11 ≠ 12), we can determine that the products of the original and reversed digits will not be the same for this pair.

Therefore, by checking the sums of the digits in the two-digit numbers, we can determine whether they will have the property of the products being the same when digits are reversed.

2.1.1 The cycle time is 45 seconds (0.75 minutes).2.1.2 The average production rate with setup time included is 9.26 stampings per minute, 2.1.3 The cost per stamping produced is Rs 0.6025.

2.1.1 To determine the cycle time, we add the time for die setup (4200 seconds), loading blanks (36 seconds), and press stroke (9 seconds), which gives a total of 4245 seconds. Converting this to minutes, we get 4245/60 = 70.75 minutes. However, since the operator is paid for 8 hours per day (480 minutes), we subtract the operator's paid time (8 minutes) to get the effective cycle time of 70.75 - 8 = 62.75 minutes, which is approximately 45 seconds.

2.1.2 The average production rate with setup time included is calculated by dividing the batch size (450 stampings) by the total time for one batch, which is the cycle time (45 seconds) multiplied by the batch size. Thus, the average production rate with setup time included is 450/(45 * 450) = 1/45 stampings per second, which is approximately 9.26 stampings per minute. Without setup time included, the average production rate is simply the batch size divided by the cycle time, which is 450/45 = 10.34 stampings per minute.

2.1.3 The cost per stamping produced can be calculated by considering the various costs involved. The labor cost per stamping is the operator's hourly rate (R16.50) multiplied by the effective cycle time in hours (62.75/60) and divided by the batch size (450). The equipment cost per stamping is the cost rate of the press (R23) multiplied by the equipment overhead rate (20%) and divided by the batch size. The die cost per stamping is the die cost (R35,000) divided by the expected number of stampings from the die (150,000). The cost per stamping related to the starting blanks is given directly as R0.43. Adding all these costs together and dividing by the batch size (450) gives the cost per stamping produced as R0.6025.

0.5 divided by 1.5 can also be written as 1/2 divided by 3/2.

So lets rewrite it like this:

(1/2)/(3/2)

From here there are two ways we can solve this. One is to multiply by the reciprocal:

(1/2) × (2/3)= 2/6

which simplifies to 1/3 as your final answer.

The other method is to "oreja"

Stress distribution can exist for a body in equilibrium if sigma x = - 2c1xy, sigma y = c2z2, sigma z = 0 tau xy = c1(c2 - y2) + c3xz, tau xz = -c3y, tau yz = 0.

Stress equilibrium specifies the pressure state of a body for a given external force field or body force distribution. The principle of stress equilibrium implies that the sum of the forces acting on the free body in equilibrium is zero, as well as the sum of the moments equal to zero.σx is the normal stress in the x direction that arises from the x-direction force acting on the plane. σy is the normal stress in the y direction that arises from the y-direction force acting on the plane.

σz is the normal stress in the z direction that arises from the z-direction force acting on the plane.τxy is the shear stress that arises from forces acting parallel to the xy plane. τxz is the shear stress that arises from forces acting parallel to the xz plane.τyz is the shear stress that arises from forces acting parallel to the yz plane.

Since there are no body forces acting on the object, it must be in equilibrium. The stress tensor is assumed to be symmetric, and the shear stresses must be equal. This is due to the plane orientation being perpendicular to the y-axis, which eliminates the need for a shear stress. As a result, we conclude that this stress distribution can exist for a body in equilibrium.

(a) The dimensions of R^n and R^m are determined by the number of rows and columns in matrix A, respectively.

(b) The image of v is obtained by multiplying matrix A with vector v.

(c) The preimage of w is the vector v that satisfies Av = w.

(a) The dimensions of R^n and R^m are determined by the number of rows and columns in matrix A, respectively. In this case, A is a 2x3 matrix, so R^n has dimension 3 and R^m has dimension 2.

(b) To find the image of v, we multiply matrix A with vector v. Given A = [[1, 0], [1, 2], [1, 0]] and v = [2, 0, 1], we have:

T(v) = Av = [[1, 0], [1, 2], [1, 0]] * [2, 0, 1]

= [21 + 01, 20 + 02, 21 + 0*0]

= [2, 0, 2]

So, the image of v is [2, 0, 2].

(c) To find the preimage of w, we need to find the vector v that satisfies Av = w. Given A = [[1, 0], [1, 2], [1, 0]] and w = [2, 0], we want to find v such that:

A*v = w

By solving the equation, we get:

[[1, 0], [1, 2], [1, 0]] * [v1, v2] = [2, 0]

This leads to the following system of equations:

v1 = 2

v1 + 2*v2 = 0

From the first equation, we have v1 = 2. Substituting this into the second equation, we get:

2 + 2v2 = 0

2v2 = -2

v2 = -1

Therefore, the preimage of w is [2, -1].

The conditional probability mass function P(X=k∣X+Y=m)= P(X=k, Y=m-k) / P(X+Y=m)

To find the conditional probability mass function P(X=k∣X+Y=m) for independent Poisson random variables X and Y, follow these steps:

1. Write down the joint probability mass function of X and Y:

P(X=k, Y=n)

= P(X=k) * P(Y=n)  since X and Y are independent.
2. Express P(X=k) and P(Y=n) using the Poisson probability mass function:

P(X=k) = (e^(-λx) * λx^k) / k! and P(Y=n) = (e^(-λy) * λy^n) / n!

3. Plug these expressions into the joint probability mass function:

P(X=k, Y=n)

= [(e^(-λx) * λx^k) / k!] * [(e^(-λy) * λy^n) / n!]

4. Write down the marginal probability mass function for

X+Y: P(X+Y=m)

= Σ [P(X=k, Y=m-k)]   for k=0 to m, where the summation is over all possible values of k.

5. Calculate the conditional probability mass function P(X=k∣X+Y=m) by dividing the joint probability mass function by the marginal probability mass function:

P(X=k∣X+Y=m) = P(X=k, Y=m-k) / P(X+Y=m)

Answer:

1) y = 2/3x - 2

2) y = -1/2x + 3

Step-by-step explanation:

1) Parallel lines have the same slopes. Write it in standard form (y = mx + c), then substitute the values of the coordinates into the equation.

y = 2/3x + c

0 = 2/3(3) + c

0 = 2 + c

0 - 2 = c

- 2 = c

Therefore, the slope-intercept form for the first part is y = 2/3x - 2.

2) Parallel lines have the same slopes. Write it in standard form (y = mx + c), then substitute the values of the coordinates into the equation.

y = -1/2x + c

1 = -1/2(4) + c

1 = -2 + c

1 + 2 = c

3 = c

Therefore, the slope-intercept form for the second part is y = -1/2x + 3.
