Answer:

<ABC = 49°

Step-by-step explanation:

The sum of two supplementary angle is 180. From the diagram, the two angles are 3x+4 and 8x+11. IF this two angles are supplementary then;

3x+4+8x+11 = 180

11x+15= 180

11x = 180-15

11x = 165

x = 165/11

x = 15

From the attached diagram, <ABC = 3x+4

<ABC = 3(15)+4

<ABC = 45+4

<ABC = 49°

Step-by-step explanation:

The standard deviation is approximately 1.3, rounded to one decimal place. The values for P(X≥5) and P(X≤3) are approximately 0.2 and 0.6, respectively, rounded to one decimal place.

To determine the standard deviation, we first need to calculate the mean. We can do this by multiplying each value of 'x' by its corresponding probability and summing them up:

Mean (μ) = (1*0.1) + (2*0.2) + (3*0.3) + (4*0.2) + (5*0.2) = 0.1 + 0.4 + 0.9 + 0.8 + 1.0 = 3.2

Next, we can calculate the variance (σ^2) by squaring the differences between each 'x' value and the mean, multiplying by their probabilities, and summing them up:

Variance (σ²) =

[tex][(1-3.2)^2 * 0.1] + [(2-3.2)^2 * 0.2] + [(3-3.2)^2 * 0.3] + [(4-3.2)^2 * 0.2] + [(5-3.2)^2 * 0.2]= \\(-2.2)^2 * 0.1] + [(-1.2)^2 * 0.2] + [(-0.2)^2 * 0.3] + [(0.8)^2 * 0.2] + [(1.8)^2 * 0.2]= \\4.84 * 0.1 + 1.44 * 0.2 + 0.04 * 0.3 + 0.64 * 0.2 + 3.24 * 0.2= 0.484 + 0.288 + 0.012 + 0.128 + 0.648 \\= 1.56[/tex]

Finally, the standard deviation (σ) is the square root of the variance:

Standard Deviation (σ) = √1.56 ≈ 1.25 (rounded to one decimal place)

To find P(X≥5), we add up the probabilities of all 'x' values greater than or equal to 5:

P(X≥5) = P(X=5) = 0.2

To find P(X≤3), we add up the probabilities of all 'x' values less than or equal to 3:

P(X≤3) = P(X=1) + P(X=2) + P(X=3) = 0.1 + 0.2 + 0.3 = 0.6

Therefore, the values are:

Standard Deviation ≈ 1.3

P(X≥5) ≈ 0.2

P(X≤3) ≈ 0.6

Answer:

m=2

Step-by-step explanation:

RS=2m+2

ST=3m+3

RT=15

m=2

RS=2(2)+2

RS=4+2

RS=6

ST=3(2)+3

ST=6+3

ST=9

Because S is in the middle of RT, if you add RS and ST together, you will get the length of RT.

The optimal solution for the primal LP is x1 = 0, x2 = 2, x3 = 2, with a maximum value of z = 16.

Let's start by writing down the dual LP. The dual LP is obtained by interchanging the roles of variables and constraints in the primal LP. The dual variables corresponding to the constraints are y1 and y2, representing the multipliers for the first and second constraint, respectively. The objective function of the dual LP is given by minimizing 4y1 + 9y2, and the dual LP subject to the dual constraints is as follows:

min 4y1 + 9y2 subject to:

2y1 + y2 ≥ 4

3y1 + 3y2 ≥ 3

y1, y2 ≥ 0

To graphically solve the dual LP, we can plot the feasible region defined by the dual constraints and find the point that minimizes the objective function. By solving the dual LP, we obtain y1 = 1/3 and y2 = 2/3, with a minimum value of 10/3. Now, using the complementary slackness conditions, we can find the set of optimal solutions for the primal LP. The conditions state that for any optimal solution, the product of the primal constraint and the dual variable must be zero. Since the primal constraints are inequalities, we consider them as equalities to check the conditions. For the first constraint, 2x1 + 2x2 + x3 = 4, we have y1(2x1 + 2x2 + x3 - 4) = 0, which gives y1 = 0. Similarly, for the second constraint, x1 + 3x2 + x3 = 9, we have y2(x1 + 3x2 + x3 - 9) = 0, which gives y2 = 0. Hence, the optimal solution for the primal LP is x1 = 0, x2 = 2, x3 = 2, with a maximum value of z = 16, satisfying the complementary slackness conditions.

Answer:

x = 22 / 2.95 :)

Step-by-step explanation:

Alright, so 2.95x + 28 = 50.

This means, (subtracting 28) that

2.95x = 50 - 28 = 22

2.95x = 22

So...

x = 22 / 2.95 :)

Answer:

The constant of variation is k = -2 ⇒ (B)

Step-by-step explanation:

The equation of the direct variation is y = k x, where

The given table has 4 points (-1, 2), (0, 0), (2, -4), (5, -10)

We can use one of the points [except point (0, 0)] to find the value of k

∵ (-1, 2) is a given point

∴ x = -1 and y = 2

∵ k = [tex]\frac{y}{x}[/tex]

→ Substitute the values of x and y in the relation above

∴ k = [tex]\frac{2}{-1}[/tex]

∴ k = -2

The constant of variation is k = -2

The equation of the Line of fit is y = 15x + 30.

The equation of the line of fit, we can use the two given points: (0, 30) and (2, 60).

First, we find the slope (m) of the line using the formula:

m = (change in y) / (change in x)

m = (60 - 30) / (2 - 0) = 30 / 2 = 15

The slope of the line is 15.

Next, we can use the point-slope form of a linear equation:

y - y₁ = m(x - x₁)

Using the point (2, 60):

y - 60 = 15(x - 2)

Simplifying the equation:

y - 60 = 15x - 30

Now, we can isolate y:

y = 15x - 30 + 60

y = 15x + 30

Therefore, the equation of the line of fit is y = 15x + 30.
