So the point must be on the graph of -f(x) is

Then right option is D

We are given a triangle such that two line segments are drawn as medians:

A meadian line has three points that are off importance as follows:

Hence, using the above information we can extract that:

We can also use the properties of median length that states:

The ratio of the above two lengths for any median line of a triangle remains true for:

This means that the line segment from centroid to bisection ( mid ) point of the opposite side is shorter than the preceeding length; hence, the ratio is ( 2 : 1 ).

We are given the length of the line segment MA the larger part of the median line:

We can use the property of ratio of lengths for the median lines and determine the length of the smaller part of the median line as follows:

From the above property we determined the length of the shorter line segment. Now we have lengths for the both constituent line segments of median line ( MX ). We can simply sum the individual lengths as follows:

Hence, the answer is:

The value of opposite side of angle θ would be,

⇒ EF

Since, A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that,

A right triangle EFD is shown in figure.

And, At angle E, right angle is shown.

We know that;

The Opposite side of a angle is called perpendicular side.

Hence, The value of opposite side of angle θ would be,

Answer:

(2x-3) and (x-5)

Step-by-step explanation:

To factor the expression (2x-3)(x-5), we can use the distributive property of multiplication over addition or subtraction:

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

Now we can use the distributive property again to factor out the common factor of (x-5):

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

So the factors of (2x-3)(x-5) are (2x-3) and (x-5).

The equation of the line perpendicular to the given line and passing through (-3, 7) is; y = (-2/3)x + 5

We are given the equation of a line as; y = (3/2)x - 1

Now, the general form of equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

Thus, for our given equation we have;

Slope; m = 3/2

y-intercept; c = -1

Now, for a line perpendicular to this, will have a slope of -1/(3/2) = -2/3

Thus, equation of the line perpendicular to the given line and passing through (-3, 7) is;

y - 7 = (-2/3)(x - (-3))

y - 7 = (-2/3)(x + 3)

y = 7 - 2 - (2/3)x

Answer:

radian

Step-by-step explanation:

A radian is a unit of angle that is equal to the angle created at the center of a circle whose arc is equal in length to the radius.

The measure of an angle at the center is 1 radian.

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Given:

Radius is equal to arc length.

To find the measure of the angle at the center:

We have the formula,

Angle in radian = arc length / radius

Let a be the arc length,

then a be the radius.

Substituting the values,

Angle in radian = a/a

Angle in radian = 1 radian

Therefore, 1 is the measure of an angle at the center.

Answer:

{-1, 0, 1, 3}

Step-by-step explanation:

A relation is a set of ordered pairs of numbers. The domain of a relation is the set of all the first elements (or x-values) in the ordered pairs. In this case, the relation is (-1,5) , (0,4), ( 1,2) , (3,-2), so the domain is the set of all the x-values in these ordered pairs, which is the set {-1, 0, 1, 3}. Therefore, the domain of the relation is {-1, 0, 1, 3}.

From the markings on the diagram, we can tell E is the midpoint of BC and D is the midpoint of AC. We can apply the triangle midsegment theorem: ED = ½BA. Substituting in the expressions for the lengths and solving for x, we get x = 5. Now, since BE = x, then BC = 10.

Triangle midpoint theorem states that the line segment which joins the midpoints of two (2) sides of a triangle is parallel to the third side, and it's congruent to one-half of the third side.

By applying the triangle midpoint theorem, we can find the value of x:

ED = ½BA

x + 2 = ½(4x - 6)

2x + 4 = 4x - 6

4x - 2x = 6 + 4

2x = 10

x = 10/2

x = 5.

BC = x + x

BC = 5 + 5

BC = 10.

Answer:

Less than 4% of a company's widgets are defective.

Step-by-step explanation:

In this case we want to be reasonably certain that less than 4% of a company's widgets are defective.

The significance level of the test is, α = 0.01.

The hypothesis can be defined as follows:  

H₀: At least 4% of a company's widgets are defective, i.e. p ≥ 0.04.  

Hₐ: Less than 4% of a company's widgets are defective, i.e. p < 0.04.  

The information provided is:  

n = 250

x = 6

The sample proportion is, \(\hat p=\frac{x}{n}=\frac{6}{250}=0.024\)

Compute the test statistic value as follows:  

 \(z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}\\\\=\frac{0.024-0.04}{\sqrt{\frac{0.04(1-0.04)}{250}}}\\\\=-1.29\)

The test statistic value is -1.29.  

The decision rule is:  

The null hypothesis will be rejected if the p-value of the test is less than the significance level.  

Compute the p-value as follows:  

 \(p-value=P(Z<-1.29)=0.0985\)

So,

p-value = 0.0985 > α = 0.01.  

The null hypothesis will not be rejected at 1% significance level.  

Thus, there is not enough evidence to support the claim.

Conclusion:

Less than 4% of a company's widgets are defective.

The number of green marbles removed from the bag is 3.

We will use the Formula of Probability:

In mathematics, the probability is defined as the ratio between the number of favorable outcomes and the total number of outcomes.

p(A) = n(A) / n(S)

p(A) is the probability of event A.

n(A) is the number of outcomes with respect to A.

n(S) is the total number of possible outcomes.

Given in the Question:

A bag contains 14 blue, 6 red, 12 green, and 8 purple marbles.

So the total number of marbles in the bag = 40

It is given that 25 marble are removed from the bag randomly

thus, the remaining marbles in the bag = 40 - 25 = 15

It is given that the probability of drawing a green marble from the bag after removing 25 marbles is 3/5.

So, for finding the number of green marbles in the bag after removing we can write,

n(A) = p(A) × n(S)

here, A is the event of drawing the number of green marbles and p(A) = 3/5 and  n(s) = 15 (after removing)

Thus, the number of green marbles in the bag after removing = 3/5 × 15

So, the number of green marbles left in the bag = 9

then, the green marbles removed from the bag = 12 - 9 = 3.

Therefore, only 3 green marbles are removed from the bag.

fractions with the same denominator added together

You must add the numerators and keep the same denominator when adding fractions with the same denominator. Since the denominators of the two fractions are the same, we must add the numerators while maintaining the same denominator, which is 4.

What are the parts of fraction?

A fraction consists of two components. The numerator is the figure at the top of the line. It details the number of equal portions that were taken from the total or collection. The denominator is the figure that appears below the line.

The number below the bar is called the denominator . It tells the number of equal parts into which the whole has been divided. The number above the bar is called the numerator. It tells how many of the equal parts are being considered.

Mixed methods research tends to be more complex when compared to quantitative and qualitative research respectively. This is because mixed methods research combines both quantitative and qualitative research methods in a single study.

Quantitative research involves the collection and analysis of numerical data, while qualitative research involves the collection and analysis of non-numerical data, such as words, images, and sounds.

Mixed methods research, on the other hand, involves the collection and analysis of both types of data. This requires the researcher to have a deeper understanding of both quantitative and qualitative research methods, as well as the ability to integrate the two types of data in a meaningful way.

Furthermore, mixed methods research often involves the use of multiple data sources, multiple research methods, and multiple levels of analysis. This adds an additional layer of complexity to the research process.

As a result, mixed methods research tends to be more complex than either quantitative or qualitative research alone.

Answer:

0.75c

Step-by-step explanation:

If we have an expression as:

a*x + b*x

We can see that both terms in the expression, a*x and b*x have an x, so we can call the x a common factor and we can write an equivalent expression as:

a*x + b*x  = (a + b)*x

If we replace, for example, a by 2, b by 3 and x by 4, we can test the expression as:

2*4 + 3*4  = (2 + 3)*4

 8   +  12  = (5)*4

    20        = 20

Therefore, if we have the following expression:

c - 0.25*c

The expression that is equivalent is 0.75c and it is calculated as:

c - 0.25*c = (1 - 0.25)*c

c - 0.25*c = 0.75*c

If you want to find the square root of a number easily, try guessing for the square roots of a number close to the number you are looking for. (This may sound confusing but I will explain don't worry)

EX: 144

Lets say that your teacher asked you to find the square root, and you don't know, so you're totally freaking out. Don't worry. Follow these steps and this will never happen.

Ok, so we know that 11 x 11 is 121, and 13 x 13 is 169. This means that since 144 is between these two numbers, the square root of 144 must also be between 11 and 13. And what do you know, its 12!

Ok, lets say we have a bigger number, such as 576.

I know, I know, this may seem like a very big number and it'll take you forever. Don't worry! We can use estimation to help us!

Ok, we know that 20 x 20 is 400, but that's to low, so we can move up a bit. 23 x 23 is 529, which is pretty close to 576, so that can be set as our minimum. 25 x 25 is 625, which is bigger than 576, so we can set that as our maximum

If we think about the problem, then we see that "Hmm, what about the number between 23 and 25? That's right! You just solved it. The square root of 576 is 24.
