Step-by-step explanation:

x + 2x + 3x = 180 (Interior angles of a triangle add up to 180 degrees)

=> 6x = 180

Dividing both sides by 6

=> x = 180 / 6

=> x = 30

Answer:

x= 30

Step-by-step explanation:

3x + 2x + x = 180

6x= 180

x = 180/6

Answer:

B) Reflection along y-axis; Translation: (x, y) → (x, y – 3)

Step-by-step explanation:

A transformation is the movement of a point from its initial position to a new position. If an object is transformed, all its points are also transformed. Types of transformation are dilatation, rotation, reflection and translation.

The point of triangle ABC are A(-4, 4), B(-7, 1) and C(-3, -2) while for triangle A'B'Ç' is at A'(4, 1), B'(7, -2) and C'(3, -5)

If a point C(x, y) is reflected along y axis, the y coordinates is the same and the x coordinate is opposite (negated), i.e C'(-x, y). If a point C(x, y) is translated 3 units down, the new point is (x, y - 3).

ΔABC transformation to ΔA'B'C', the x coordinate is opposite and the y coordinate is 3 units downward, therefore this is a Reflection along y-axis; Translation: (x, y) → (x, y – 3)

Answer: c

Step-by-step explanation:

The answer is c bc you reflect across the y axis and then translate

Answer:

5 cm

Step-by-step explanation:

As we can see in the attached figure that G is the point at which the three medians of the triangle meet i.e we called the centroid

And, according to the property of the centroid, it divides the medians in ratio i.e 2:1

DG: CG = 2 : 1

Since the DG is 10 cm

So, the CG would be half of DG i.e 5 cm

Hence, the CG is 5 cm

Therefore the first option is correct

Answer:

the answer is 5 cm

Step-by-step explanation:

Answer:

m= -29

Step-by-step explanation:

This is a bit of a complex equation, but let's work through it.

2/3 (m-1/2) +3= m/3-7

First, we need to distribute the 2/3.

(2/3)(m)+(2/3)(−1/2)+3=m/3+−7

Now we simplify that.

2/3m+−1/3+3=1/3m+−7

We can now combine like terms.

2/3m+8/3=1/3m+−7

The goal is to isolate the variable, so we should subtract 1/3m from both sides.

1/3m+8/3=−7

Lets keep going! We can subtract 8/3 from both sides.

1/3m=-29/3

Well now we know what 1/3 of m is, but we want to know what m is. So we can multiply both sides by three to finally find out what m is!

m=-29

We did it! m=-29

Answer:

Rs 416

Step-by-step explanation:

Given,

Cost Price ( CP ) = Rs 400

Profit % = 4 %

Selling price ( SP ) = ?

now, Let's find the value of SP:

SP = [tex] \frac{CP \: (100 + \: profit percent \: )}{100} [/tex]

Plug the values

[tex] = \frac{400(100 + 4)}{100} [/tex]

Add the numbers

[tex] = \frac{400 \times 104}{100} [/tex]

Multiply the numbers

[tex] = \frac{41600}{100} [/tex]

Divide

= Rs [tex]416[/tex]

Selling price ( SP ) = Rs 416

Answer:

B. The student incorrectly calculated the scale factor to be –2

Step-by-step explanation:

Given that :

After a dilation with a center of (0, 0), a point was mapped as (4, –6) → (12, y).

The student determined y to be -2

If a figure dilated with a center of (0, 0) and scale factor k, then

(x , y) → (kx , ky)

(4, -6) → (12, y)

[tex]k = \dfrac{x'}{x}[/tex]

[tex]k = \dfrac{12}{4}[/tex]

k = 3

Thus; the scale factor is 3

Now; the y-coordinate can now be calculated as;

ky = (3 × -6)

ky = -18

Therefore; the value of y = -18 and the student incorrectly calculated the scale factor to be -2.

The last graph is the correct answer

Step-by-step explanation:

Here, we are interested in picking the correct graph that best answers the question.

Before we pick any of the graphs as our answer, it will be appropriate to solve the inequality.

-4h + 42 <34

-4h < 34-42

-4h < -8

Now divide both side by -4; kindly note that when dividing an inequality by a negative number, the sign will change

h > -8/-4

h > 2

So which of the graph best showcases this?

The correct answer is the last graph

Answer:

Mean = 2.14

Standard deviation = 2.40

Step-by-step explanation:

The calculation of mean and standard deviation is shown below:-

[tex]X = .07\times0 + 0.20\times 1 + 0.38\times 2 + 0.22\times 3 + 0.13\times 4\\\\ = 0 + 0.2 + 0.76 + 0.66 + 0.52[/tex]

= 2.14

So, the mean is 2.14

Now, For computing the standard deviation first we need to find out the variance which is shown below:-

Variance is

[tex]Var(X) = P(X^2) - [P(X)]^2\\\\ P(X^2) = .07\times (0^2) + .20\times (0^1) + .38\times (0^2) + .22\times (0^3) +0.13\times (0^4)[/tex]

After solving the above equation we will get

= 5.78

Now, the standard deviation is [tex]= \sqrt{Variance}[/tex]

[tex]= \sqrt{5.78}[/tex]

= 2.404163056

or

= 2.40

Answer: d. 0.0047

Step-by-step explanation: The p-value is the calculated value used to compare to the significance level to determine if you reject or fail to reject the null hypothesis.

To find p-value, first find the z-score:

z = [tex]\frac{x-\mu}{SE}[/tex]

x is sample mean

μ is population mean

SE is standard error calculated by [tex]\frac{s}{\sqrt{n} }[/tex]

SE = [tex]\frac{10}{\sqrt{50} }[/tex]

SE = 1.414

z = [tex]\frac{24-28}{1.414}[/tex]

z = - 2.83

The hypotheses ([tex]H_{0}, H_{a}[/tex]) are if sample mean is equal or different from the average given, so, p-value will be the value of z from z-table multiplied by 2:

p-value = 0.00233*2

p-value = 0.0047

The p-value for this test is 0.0047

Answer:

y = [tex]-\frac{2}{3} x[/tex] - [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

The line (l1) passes through (-2, 1) and is perpendicular to the line whose equation is;

3x - 2y = 5

Converting this equation to slope intercept form gives;

2y = 3x - 5

y = 1.5x - 2.5

Let the slope of the perpendicular line (l2) be m(PERP).

The product of slopes of two perpendicular lines is -1

The slope of our first line (l1) = 1.5

So 1.5 × m(PERP) = -1

m(PERP) = -1 ÷ 1.5 = [tex]-\frac{2}{3}[/tex]

Taking another point (x,y) on line (l2);

[tex]\frac{y - 1}{x + 2} = -\frac{2}{3}[/tex]

Cross multiplying this gives;

y = [tex]-\frac{2}{3} x[/tex] - [tex]\frac{1}{3}[/tex]

which is the equation of our second line (l2).

Multiply the second equation by 9.

Step-by-step explanation:

To use the elimination method, you need to be able to add the equations and have one variable add to zero. That way you eliminate that variable.

The first equation has -9y. The second equation has y. If you multiply the second equation by 9, you will have 9y in the second equation. Then when you add equations, you will add -9y and 9y and will eliminate y.

Answer: Multiply the second equation by 9.

Answer:

Step-by-step explanation:

6x - 9y = 21

-6x -2y = -10

-11y = 11

What is Expression?

An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context

Given,

The first company pays a salary of $10,000 plus a commission of $1,000 for each car sold

therefore the expression is

10000+1000x

where x is the number of car sold

The second pays a salary of $20,000 plus a commission of $500 for each car sold

Then the expression will be

20000+500x

How many cars would need to be sold to make the total pay the same is

10000+1000x=20000+500x

1000x-500x=20000-10000

500x=10000

Answer:

Step-by-step explanation:

All of these statements about a vertical parabola with known vertex are true.

The statement which is not always true about the graph of a quadratic function is option d) the parabola is symmetrical about the y-axis.

What is Parabola?

A parabola is a open U shaped curve on a plane where all the points on the curve will be at an equal distance from a fixed point called focus and a fixed line called directrix.

Vertex of a parabola is the point where the parabola intersects with it's line of symmetry. So the vertex will always lie at the maximum point or the minimum point.

Axis of symmetry is the line that passes through the vertex of a parabola.

Graph of the quadratic equation will always be a parabola.

When the coefficient of x² is positive, then the vertex of the parabola will be at a minimum point and if the coefficient is negative, then the vertex will be at a maximum point.

The parabola is symmetrical to y axis only if the vertex of the parabola lies on the Y axis. So it will not be always true.

Hence the statement the parabola is symmetrical about the y-axis is not always true.
