Answer:

Step-by-step explanation:

In parallel lines gradient are the same so first re-arrange the given equation.

1. Ax+By=C

2. The equation is given in standard format [tex]3x-y=4[/tex]

Solve for m.

1. [tex]3x-y=4[/tex]

2. [tex]\frac{3x}{3} =\frac{4}{3}+\frac{y}{3}[/tex]

3. [tex]x=\frac{4}{3}+\frac{y}{3}[/tex]

Find the value of b using the formula for the equation of line.

[tex]y=mx+b[/tex]

Substitute the value of m into the equation.

[tex]y=(\frac{4}{3}+\frac{y}{3}) . x+b[/tex]

Substitute the value of x into the equation

[tex]y=(\frac{4}{3}+\frac{y}{3}).(3)+b[/tex]

Substitute the value of y into the equation

[tex]2=(\frac{4}{3}+\frac{2}{3}).(3)+b[/tex]

Find B

[tex]b= -4[/tex]

Now we know the value of m and b. Substitute them into y=mx+b to find the equation of the line.

[tex]y=\frac{4}{3} x+\frac{1}{3} yx-4[/tex]

Answer:

Option B

Step-by-step explanation:

For the polygons to be similar, the dilation ratio must be uniform for all sides.

>> In option A, each side of the bigger hexagon is 8cm while each side of the smaller one is 5 cm. Thus, the dilation ratio is uniform at 8:5. Thus, they are similar polygons.

>> In option B, the longer side of the big rectangle is 12 inches and reduces to 10 inches. Which means a ratio of 6:5 whereas, the shorter side reduces from 7 to 6 which is a ratio 7:6. Since both ratios are different, then it means that both rectangles are not similar.

>> In option C, the hypotenuse of the big triangle is 15 m and reduces to 10 m in the small triangle. This gives a ratio of 3:2.

The perpendicular side of the big triangle is 9m which reduces to 6 m in the small one. This is a ratio of 3:2.

The horizontal side of the big triangle 12m which reduces to 8m in the small triangle. This is a ratio of 3:2.

Since all the ratios are same, then they are similar triangles.

>> In option D, each side of the bigger polygon is 7ft while each side of the smaller one is 4ft. Thus, the dilation ratio is uniform at 7:4. Thus, they are similar polygons.

(a) The marginal distribution of X is

Pr(X = x) = ∑ Pr(X = x, Y = y)

… = 0.0625 + 0.0625 + 0.0625 + 0.0625

… = 0.25

That is, the first equality follows from the law of total probability, with the sum taken over y from {0, 5, 10, 15}. Each probability Pr(X = x, Y = y) is given in the table to be 0.0625.

Similarly, the marginal distribution of Y is

Pr(Y = y) = 0.25

(b) Yes, they're independent because

Pr(X = x, Y = y) = 0.0625,

and

Pr(X = x) Pr(Y = y) = 0.25 • 0.25 = 0.0625.

(c) The mean of X is

E[X] = ∑ x Pr(X = x)

… = 0.25 ∑ x

… = 0.25 (0 + 5 + 10 + 15)

… = 7.5

and you would find the same mean for Y,

E[Y] = 7.5

The variance of X is

V[X] = E[X^2] - E[X]^2

… = (∑ x^2 Pr(X = x)) - 7.5^2

… = 0.25 (∑ x^2) - 56.25

… = 0.25 (0^2 + 5^2 + 10^2 + 15^2) - 56.25

… = 31.25

and similarly,

V[Y] = 31.25

(each sum is taken with x and y from {0, 5, 10, 15})

Answer:

The opportunity cost of playing an hour of video games is not reading 3 chapters of a book.

Step-by-step explanation:

Given that Anthony can either play 4 hours of video games or read 12 chapters of a book, to determine what is Anthony's opportunity cost of playing one hour of video games, the following calculation must be performed:

4 = 12

1 = X

1 x 12/4 = X

12/4 = X

3 = X

Therefore, the opportunity cost of playing an hour of video games is not reading 3 chapters of a book.

Answer:

[tex]\text{1. }\triangle IJH\cong \triangle LKM, \\\text{2. }\triangle RST\cong \triangle YXZ, \\\text{3a. Reflexive Property}, \\\text{3b. ASA (Angle-Side-Angle)}[/tex]

Step-by-step explanation:

ASA (Angle-Side-Angle) is a proof of congruence that states if two triangles share two angles and the side between those two angles, the triangles are congruent. In problems 1 and 2, the following demonstrate this:

[tex]\text{1. }\triangle IJH\cong \triangle LKM, \\\text{2. }\triangle RST\cong \triangle YXZ[/tex]

In problem 3, [tex]\overline{IJ}\cong \overline{IJ}[/tex] is known in geometry as the Reflexive Property. Because of this, the two triangles in the diagram for problem 3 now share two angles and the side between them, thus they are congruent from ASA (Angle-Side-Angle).

Answer:

1.246

Step-by-step explanation:

First, you divide 3.560 by 100%, which gives you 3.56. Now since you have the number of applications received each, you now multiply 3.56 by 35%, or 0.35, which then gives you 1.246.

arcsin(5/6) = 56.44 degrees, or 0.99 radian

Step-by-step explanation:

Write out sin x = 5/6.

Then write out the inverse function:  arcsin 5/6 = x.

Use a calculator's 'arcsin' function to determine the angle x:

arcsin(5/6) = 56.44 degrees, or 0.99 radian

The probability that he rolls a sum of 9  given the sample space is . 9/36, or 1/4.

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability that he rolls a sum of 9 = cubes that have a sum of 9 / total number of cubes

9/36 = 1/4

Answer:

90 engines must be made to minimize the unit cost.

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

[tex]f(x) = ax^{2} + bx + c[/tex]

It's vertex is the point [tex](x_{v}, y_{v})[/tex]

In which

[tex]x_{v} = -\frac{b}{2a}[/tex]

[tex]y_{v} = -\frac{\Delta}{4a}[/tex]

Where

[tex]\Delta = b^2-4ac[/tex]

If a>0, the minimum value of the function will happen for [tex]x = x_v[/tex]

C(x)=x²-180x+20,482

This means that [tex]a = 1, b = -180, c = 20482[/tex]

How many engines must be made to minimize the unit cost?

x value of the vertex. So

[tex]x_{v} = -\frac{b}{2a} = -\frac{-180}{2(1)} = 90[/tex]

90 engines must be made to minimize the unit cost.

The distance between gab's house and library will be 4km

Distance is a numerical measurement  of how far apart object or point are or it may also refer as the physical length.

From graph we can see that Gabe's house is 3 km on positive x axis in respect to the origin

Whereas library is 1 km apart from origin on negative x axis

Since we are calculating distance , we simply add both the above mentioned distances irrespective of their direction since distance is a scaler quantity.

Distance between Gab's house and library will be :
