There are 20 orchestra students, and 4 of them have a solo. Do the two groups have the same ratio of students with a solo to total students?

When a predictive model is made overly complex to fit in the quirks of given sample data, it is called overfitting.

Overfitting occurs when a model is too complex and tries to fit the data too closely. This can result in a model that performs well on the training data but performs poorly on new, unseen data.

Overfitting can be prevented by simplifying the model or using a larger training dataset. It is important to strike a balance between complexity and simplicity in order to create a model that generalizes well to new data.

Answer:

Step-by-step explanation:

if you used a compound statement, it would look like this.

2/7 < 1/2 < 5/8

One half is bigger than 2/7. It is much closer to 1/4 than 1/2. 1/4 = 2/8 so 2/7 is just a little bit less than that.

On the other hand 1/2 is just smaller than 5/8. 1/2 = 4/8 so you can see that 1/2 is less than 5/8.

Answer:

for the first picture, she cleans 30 windows

the second picture is 52/100 :)

Answer:

It's B for the first one.

For the second one, it is C

Step-by-step explanation:

30 * 0.3 = 9

So 30% of 30 is 9. She did 9 windows.

0.52 = 52/100

It's 52/100 because 0.52 = 52%. 52% then equals 52/100.

52/100 = 13/25

So the answer is 13/25

L = k/f, where k is the variational constant, is the formula for the inverse variation.

A mathematical relationship between two variables in which they vary in opposing directions is referred to as an inverse proportion, also known as an inverse relationship. When one variable increases while the other decreases, this is known as having inverse proportions.

Using the variables length of violin 'l' and frequency of vibration 'f'

If the length of violin 'l' is inversely proportional to the frequency of vibration 'f', this is expressed as:

l α 1/f

l = k/f

Hence the formula for the inverse variation is l = k/f where k is the constant of variation.

Sin = Opposite/Hypotenuse

Cos = Adjacent/Hypotenuse

Tan = Opposite/Adjacent

Answer:

tanθ=6/8, sinθ=6/10, cosθ= 8/10

Step-by-step explanation:

the ratio of tan is opposite over adjacent from the angle's perspective, and 6 is opposite whereas 8 is adjacent so tan(x)=6/8

the ratio of sin is opposite over hypotenuse from the angle's perspective, where 6 is opposite from it whereas the hypotenuse will always be the side opposite to 90 so it's 10 so sin(x)=6/10

the ratio of cos is adjacent over the hypotenuse from the angle's perspective, where 8 is adjacent to it whereas 10 is the hypotenuse so the ratio will be cos(x)=8/10

Answer:

\(E =\) \((-3,3)\)

Step-by-step explanation:

Given

Parallelogram: DEFG

\(D(x_1,y_1) = (-2,-4)\)

\(F(x_3,y_3) = (0,7)\)

\(G(x_3,y_4) = (1,0)\)

Required

Find the coordinates of \(E(x_2,y_2)\)

To do this, we make use of mid-point formula which is:

\(M = (\frac{x_1+x_3}{2},\frac{y_1+y_3}{2})= (\frac{x_2+x_4}{2},\frac{y_2+y_4}{2})\)

This gives:

\((\frac{-2+0}{2},\frac{-4+7}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})\)

\((\frac{-2}{2},\frac{3}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})\)

Multiply through by 2

\(2 * (\frac{-2}{2},\frac{3}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})*2\)

\((-2,3) = (x_2+1,y_2+0)\)

\((-2,3) = (x_2+1,y_2)\)

By comparison:

\(-2 = x_2 + 1\) and \(3= y_2\)

So, we have:

\(-2-1=x_2\) and \(3= y_2\)

\(-3 = x_2\) and \(3 = y_2\)

This gives:

\(x_2 = -3\) and \(y_2 =3\)

The declaration states that the value of Arc EFC = 253°.

A measure is indeed a quantitative concept used to express how large a collection is. Each unique measure represents a different method for determining how large a collection is. It would initially appear that a set's cardinality is the only logical way to determine its number.

We can tell we are working with a circular that has 360 degrees because of the connection.

We can infer that we have it if we look at that file.

Arc EFC

Arc CD

Arc DE

And everything together give us 360,

Arc EFC + Arc CD + Arc DE = 360

If we examine the figure again, we can see that the central angle of an intercepted arc is identical to the arc's measure.

Arc CD is 90 degrees since the central angle is 90 degrees given

Arc DE is 17 degrees

Arc EFC + Arc CD + Arc DE = 360

If we input all the figures

Arc EFC + 90 + 17 = 360

Arc EFC + 107 = 360

Arc EFC = 360 - 107

Arc EFC = 253

Therefore, Arc EFC = 253°

Answer:

L’ is (-4,-1)

M’ is (-8,-5)

N’ is (-6,-7)

P’ is (-2,-3)

Step-by-step explanation:

Here, we want to from new vertices by translation followed by reflection;

When we reflect , we simply change the sign of the x-coordinates if we are reflecting over the y-axis

We proceed as follows;

1. L (-2,7)

Translation will be (-2 + 6, 7-8) = (4,-1)

Reflection will be ( -4,-1)

so L’ is (-4,-1)

2. M (2,3)

Translation will be

(2 + 6, 3-8) = (8,-5)

Reflection will be ( -8,-5)

So M’ is (-8,-5)

3. N (0,1)

translation will be

( 0 + 6, 1-8) = (6,-7)

Reflection will be ; (-6,-7)

4.P (-4,5)

Translation will be (-4 + 6, 5-8)

= (2, -3)

Reflection will be;

(-2, -3)

P’ = (-2,-3)

The name of the segment inside the large triangle is called the: 3. angle bisector.

The word "bisect" means to divide into two equal halves. Therefore, an angle bisector can be defined as a line segment that divides the an angle in a triangle into two parts that are of the same angle measure.

The image shows a triangle which has a segment that divides a vertex angle into equal parts. Thus, the segment can be named as an angle bisector.

A perpendicular bisector divides a segment into two equal halves at right angle, while a midsegment joins the middle points of two sides of a triangle. The median also, is a segment that joins a vertex of a triangle to the midpoint of the side that is opposite the angle.

Therefore, we can state that the name of the segment is: 3. angle bisector.

Formula for the Slope: (y2 - y1) / (x2 - x1)

You can use any two points to find the slope, as long as those two points are on the line.

Point 1 = (-2, 8)

Point 2 = (0, 0)

Slope = (0 - 8) / (0 - - 2)

Slope = -8 / 2

Slope = -4

Hope this helps!

Answer:

-4

Step-by-step explanation:

The formula to find the slope is (change in y)/(change in x). In other words, rise over run.

If we look at the data, we can see that the x and y value changes.

x value: -3 --> -2 --> -1 --> 0 --> 1

y value: 12 --> 8 --> 4 --> 0 --> -4

When y changed from 12 to 8, the x changed from -3 to -2.

y: 12 --> 8

x: -3 --> -2

There was a difference of -4 in the y and a difference of 1 in the x.

At the top, I wrote that the slope was (change in y)/(change in x)

With -4 and 1 we found, we can say that the slope is -4/1.

If we simplify this answer, we end up with -4.

So -4 is the slope of the data.

Answer: No solution

Step-by-step explanation:

To use elimination method, we need to choose a variable to eliminate. Let's eliminate x. To eliminate x, the x coefficient in both equations must be the same, regardless of the sign. To do so, let's multiply the first equation by 2.

(2x+y=4)2

-4x-2y=8

-------------------------------------------------------------------------------------------------------------

4x+2y=8

-4x-2y=8

Let's add both equations together.

0=8

-------------------------------------------------------------------------------------------------------------

Now that we got this far, we can see that something is wrong. This normally doesn't happen. If you notice, the second equation is the first equation but multiplied by 2. Instead, let's rewrite each equation.

2x+y=4              [subtract both sides by 2x]

y=-2x+4

-4x-2y=8           [add both sides by 4x]

-2y=4x+8          [divide both sides by -2]

y=-2x-4

-------------------------------------------------------------------------------------------------------------

If you analyze both equations, you will see that they are parallel lines. We know this because the slopes are the same, but different y-intercept. from our knowledge of parallel lines, they NEVER touch or cross. This means there would be no solution at all.

We are given that ABC is a triangle in which AB = AC.

A circle passing through B and C also intersects the sides AB and AC at points D and E respectively.

And we want to prove that AD = AE.

By the secant-secant theorem (shown below), we know that:

\(AD(AB)=AE(AC)\)

We are given that AB = AC. So, by substitution:

\(AD(AB)=AE(AB)\)

And by dividing both sides by AB (AB ≠ 0), we acquire:

\(AD=AE\)
