What is Combination?

Combinations are mathematical operations that count the number of potential configurations for a set of elements when the order of the selection is irrelevant.

Mathematically, a combination is a selection of things without regard for order.

The formula for “combination with replacement” is:

   [tex]C^{R} (n,r)=\frac{(n+r-1)!}{r! (n-r)!}[/tex]

10 choose 3 with replacement gives you a mere 220 combinations.

Answer:

  P(x) = (x +1)(x -2)(x -4)

  see the 2nd attachment for a graph

Step-by-step explanation:

You want the factors of P(x) = x³ - 5x² + 2x + 8, given that (x+1) is one of the factors. You also want a graph of it.

The quotient from dividing P(x) by the given factor will be a quadratic we can factor to find the other two binomial factors. The first attachment shows that quotient is (x² -6x +8).

To factor this quadratic, we look for factors of 8 that have a sum of -6. They are -2 and -4. Hence the remaining binomial factors are (x -2)(x -4).

The desired product is ...

  P(x) = (x +1)(x -2)(x -4)

The second attachment shows a graph of P(x). The y-intercept is the constant in the equation, 8. The x-intercepts are the values of x that make the factors zero.

No , Dilation doesn't increase the measure of angles

Dilation is a transformation, which is used to resize the object. Dilation is used to make the objects larger or smaller.

This transformation produces an image that is the same as the original shape. But there is a difference in the size of the shape.

The new figure obtained after dilation is called the image and the original image is called the pre-image

We dilate any figure by scale factor.

Dilated figures will always be similar figures.

Similar figures have the same shape, angles with the same measures, and the lengths of corresponding sides have equal ratios. The ratio is the same as the scale factor of the dilation.

If winners are chosen randomly from the 300 people who bought this lottery, the expected profit of a random person is $0.766..

The expected profit under a probability demand distribution is calculated by multiplying the profit amount by the probability of achieving that profit.

It is denoted as E(X) . We have given that,

A $1 lottery ticket has a number of prizes.

Probability of winning first prize , $10 = p₁ = 3/300 = 1/100

probability of winning a 2nd prize, $50

= p₂= 2/300= 1/150

probability of winning a 3rd prize, $100

= p₃ = 1/300 = 1/300

E = expectation value = ∑ Vᵢpᵢ where Vᵢ = value of prize, pᵢ = probability of winning prize,

E = $10 ×1/100 + $50×1/150 + $100×1/300

=> E = $10/100 + $50/150 + $100/300

Taking LCM as 300 on right hand side,

=> E =( $30+ $100+$100)/300

=> E = $(230/300) = $0.766

So, expected winnings for a person buying one ticket is $0.766..

Therefore ,  95% confidence interval for the difference in mean mcls levels is 95% C.I = {4.0978 , 3.1423}.

In frequentist statistics, a confidence interval is a range of estimates for an unobserved parameter. The most frequent confidence level is 95%, while other levels, such 90% or 99%, are occasionally used for computing confidence intervals.

Here,

Given:

c= 1.95 M.E = 0.5 ,n=?,C.V=1.96

Using formula,

=> M.E = C.V + [tex]\frac{c}{\sqrt{n} }[/tex]

=> 0.5 = 1.96 + 1.95/[tex]\sqrt{n}[/tex]

=> 0.5 = 3.822/[tex]\sqrt{n}[/tex]  

=> [tex]\sqrt{n}[/tex]  = 3.822/0.5

=> [tex]\sqrt{n}[/tex]  = 7.644

=> n =58.43

=> n ≈ 58

So, n = 64 , [tex]x^{'}[/tex]=3.62,α=1.95

=> u = [tex]x^{'}[/tex] ± C.V * α/[tex]\sqrt{n}[/tex]

=> u = 3.62 ±  1.96 * 1.95/√64

=>  u = 3.62 ± 0.47775

=>  u = 3.62+ 0.47775 = 4.0978

 or u=3.62-0.47775 = 3.1423

95% C.I = {4.0978 , 3.1423}

Step-by-step explanation:

The number of crayons is equal to 8 times the number of boxes.

By using the fact that the sum of the internal angles must be equal to 360°, we will see that x = 18

Suppose we have a figure of N sides, the sum of the internal angles of that figure will be equal to:

S = (N - 2)*180°

In this case, we have 4 sides, then:

S = (4 - 2)*180° = 360°

Also notice that the figure is symmetrical around the two vertical vertices, then the angle at the left side (the only one that we don't know) also measures 101°, like the one in the right side.

Then we can write the linear equation:

100° + 101° + 101° + (4 + 3x)° = 360°

Now we can try to solve this for x.

(100° + 101° + 101°) + (4 + 3x)° = 360°

302° + (4 + 3x)° = 360°

(4 + 3x)° = 360° - 302°

4 + 3x = 58

3x = 58 - 4 = 54

x = 54/3

x = 18

Step-by-step explanation:

The measure of angle 2 is 61 degrees.

The measure of angle 4 is 119 degrees.

What is triangle?

A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

In the given triangle the measure of two triangles is given which is 61° and 58°.

We have to solve for the measure of angle 2.

Since, the sum of three angles of triangle's is 180 degrees.

⇒ 61° + 58° + ∠2 = 180°

          119 ° + ∠2 = 180°

                     ∠2 = 180° - 119°

                     ∠2 = 61°

Hence, the measure of angle 2 is 61 degrees.

Now to find measure of angle 4.

Here ∠2 and ∠4 are planer angles and their addition is 180°.

⇒ ∠2 + ∠4 = 180°

61° + ∠4 = 180°

∠4 = 180° - 61°

∠4 = 119°

Hence, the measure of angle 4 is 119°.

What is congruent triangles?

If the three sides and the three angles of both angles are equal in any orientation, two triangles are said to be congruent.

The SAS formula states that if two sides and one angle of two triangle are the same then the triangles are congruent to each other.

Two lines AD, EC intersects each other at the point B . Therefore, ∠ABC = ∠DBE  .

The length of the sides AC = DE, BC = BE .

The triangles ΔABC, ΔBDE  are congruent to each other by the SAS formula.

The SSS formula states that two triangles are congurent to each other if the ratio of corresponding sides of two triangles are the same and vice-versa.

Use the SSS formula in the triangles ΔABC, ΔBDE and simplify to calculate the length of BD.

BD/200 = 300/300

BD/200 = 1

BD = 200  

Therefore, using SSS the length of the road from the intersection to the first turn can be found to be 200ft.

Add the lengths of AB, BD, DE, EB, BC, CA to calculate the total length of the tour.

200 + 200 + 300 + 350 + 350 + 300 = 1700

The total length of the tour is 1700ft.

Step-by-step explanation:

From inspection of the graph, two points on the line are:

Substitute these points in the slope formula to find the slope of the line:

[tex]\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{2-6}{2-1}=\dfrac{-4}{1}=-4[/tex]

Lines that are parallel have the same slope.

Therefore, a line parallel to the given line has a slope of -4.

To write an equation of the parallel line, substitute the found slope and point (4, 3) into the point-slope formula and rearrange:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-3=-4(x-4)[/tex]

[tex]\implies y-3=-4x+16[/tex]

[tex]\implies y=-4x+19[/tex]

If two lines are perpendicular to each other, their slopes are negative reciprocals.

Therefore, a line perpendicular to the given line has a slope of ¹/₄.

To write an equation of the parallel line, substitute the found slope and point (4, 3) into the point-slope formula and rearrange:

These points often may be intercepts of the x and/or y axes.

The equation of the slope is given by-

2. The second condition is where you are given the linear equation that is either in the form or can be manipulated into the form y=mx+b.

3. The third case is when you have a line that is a tangent to another function, you may have (or be able to determine) the slope of the tangent as the derivative of the function. Normally in such cases, the derivative is a function expressed in terms of x and all you need to do is substitute the value of x into this function for the required equation.

4. The fourth case is when you are given a graph as follows-
