The hypotheses that would determine if the proportion of households that support starting school earlier has changed this year is C. H 0: p = 0.65, H alpha: p greater-than 0.65.

A statistical hypothesis known as a null hypothesis asserts that no statistical significance can be found in a given set of observations.

It is tested to see if there has been no change at the null hypothesis, which means that the proportion is still 0.65 = 65%.

It is tested whether there has been a change at the alternative hypotheses, that is, whether the proportion is no longer 0.65 = 65%.

If the given triangle has all three sides as congruent and the angles are same then the triangle is an equilateral triangle.

We will use the figure given below to prove the triangle as an equilateral triangle.

In the above figure,

Given, vertices of a triangle are A(X1, Y1), B(X2, Y2), and C(X3, Y3).

According to the properties of the equilateral triangle, the sides of an equilateral triangle should be equal in measure.

So, we use the distance formula:

d = √((x2 - x1)^2+(y2 - y1)^2 to verify if all three sides are congruent and equal to each other

If AB = BC = CA.

⇒ √((x(2) - x(1))^2 + (y(2) - y(1))^2) = √(x(3) - x(2))^2 + (y(3) - y(2))^2 = √(x(1) - x(3))^2+ (y(1) - y(3)) ^2

If the given triangle satisfies the above condition then the triangle is an equilateral triangle.

If the given triangle has all three sides as congruent then the triangles angles are also equal.

Hence, if the given triangle has all three sides as congruent and the angles are same then the triangle is an equilateral triangle.

The slope of the line described by the equation 15x – 10y = 10 is m = 15/10 = 1.5, and the y-intercept is b = 10/15 = 2/3.

Step-by-step explanation:

Answer:Slope is 1.5, and the y-intercept is -1

Step-by-step explanation:

So in order to get the slope and y-intercept, you have to put the equation in slope form, y=mx+b

Here’s the work for it

15x-10y=10

-15x -15x

-10y=-15x+10

Now divide -10 on both sides

y=1.5x-1

Now that it’s in the right form, you can easily see the slope is 1.5 and the y-intercept is -1

During rigid transformations, the shape, size, and orientation of an object remain the same, while its position in space changes. This means that the distance between any two points on the object remains constant, as does the angle between any two lines. Additionally, the orientation of the object's axes (length, width, and height) remain the same.

Transformations are a general term for four different methods of changing the location and/or shape of a point, line, or geometric figure. The shape of the object is revealed in its pre-image, while its final form and position are revealed in the image following transformation.

A transformation is characterized by a significant alteration in appearance or form. Your life may change as a result of a significant event, such earning your driver's license, beginning college, or getting married. A significant, abrupt transformation is called a metamorphosis.

The best example of discontinuity is a graph of a function with a "hole" or "jump" in it, where the value of the function suddenly changes without any gradual change.

Discontinuity occurs when a graph of a function has an abrupt change, either in the form of a "hole" or "jump" in it. In a graph of a continuous function, the values gradually change in a smooth manner. However, with a graph of a discontinuous function, the function suddenly changes without any gradual transition. This sudden change is often caused by a discontinuity in the domain or range of the function. For example, a discontinuity may occur where a function is undefined or has an undefined limit. Graphically, this is usually illustrated as a gap or jump in the graph of the function. This type of discontinuity is known as a removable discontinuity, since it can be removed by redefining the function at the point of discontinuity. Other types of discontinuity include infinite discontinuity, which occurs when the graph of a function approaches either positive or negative infinity, and jump discontinuity, which occurs when the graph of a function jumps from one value to another without any transition.

Answer:

The distance between the points R(a+b,a-b) and S(a-b,a+b) is 2*sqrt(2)*sqrt(a^2+b^2).

Step-by-step explanation:

To find the distance between the two points, we can use the distance formula:

distance = sqrt((x2-x1)^2 + (y2-y1)^2)

Plugging in the coordinates of the two points, we get:

distance = sqrt((a-b-a-b)^2 + (a+b-a+b)^2)

Simplifying, we get:

distance = sqrt(2*(a^2 + b^2))

Multiplying both sides by sqrt(2) gives us:

distance = 2*sqrt(2)*sqrt(a^2+b^2)

Therefore, the distance between the points R(a+b,a-b) and S(a-b,a+b) is 2*sqrt(2)*sqrt(a^2+b^2).

Look at the hundredth number to round the decimal number to the nearest tenth. If it's more than 5, add one to the tenth value. Remove all the numbers that are present after the tenth place and leave the tenth place value alone if it is less than 5.

The length of sides of the triangle are x, 35, and 40.

Assume that AB = c = x, BC = a = 35, and AC = b = 40

m∠C = 45° and m∠B = y°.

Cosine law:

c² = a² + b² - 2ab cos C  ....(i)

b² = a² + c² - 2ac cos B  ....(ii)

a² = b² + c² - 2bc cos A  ....(iii)

Putting a = 35, b = 40, c = x, and C = 45° in law (i)

x² = 35² + 40² - 2×35×40 cos 45°

x² = 2825 - 2800 × (1/√2)

x = 29.07

x = 29.1  (nearest tenth)

Putting a = 35, b = 40, c = 29.1, and B = y° in law (ii)

Continuity of a function is when the function is continuous over the range of its domain. A function is continuous if the graph of the function is a single, connected curve with no breaks or gaps. This means that for any point on the curve, the function is non-discontinuous. An example of a continuous function is f(x) = x^2, which is continuous over its domain of x∈R. This means that, no matter what value is put into the function, the output will always be a single value and the graph of the function will be a single, connected line. This is because the function is continuous over its entire domain, and therefore there are no breaks or discontinuities in the function. This is an example of continuity of a function.

Number words are a linguistic way to express numbers.

So, let the ones and tens places' digits be y and x, respectively.

initial value = 10x+y

number in reverse = 10y plus x

In response to the query:

3(10x+y)-9 = 10y+x

30x+3y-9-10y-x= 0

29x-7y-9 = 0 ...(1)

AAS (Angle-Angle-Side): If two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of a second triangle, then the two triangles are congruent. Hence proved

AAS (Angle-Angle-Side):

Suppose we have two triangles from figure ABC and DEF, where,

∠B = ∠E [Corresponding angles] ∠C = ∠F [Corresponding angles] And

AC = DF [Adjacent sides]

By angle sum property of triangle, we know that;

∠A + ∠B + ∠C = 180 ………(1)

∠D + ∠E + ∠F = 180 ……….(2)

From equation 1 and 2 we can say;

∠A + ∠B + ∠C = ∠D + ∠E + ∠F

∠A + ∠E + ∠F = ∠D + ∠E + ∠F [Since, ∠B = ∠E and ∠C = ∠F] ∠A = ∠D

Hence, in triangle ABC and DEF,

∠A = ∠D

AC = DF

∠C = ∠F

To find the vertical asymptote, look for the values of x where the denominator of a function equals 0. To find the removable discontinuity, look for the values of x where the numerator of a function equals 0.

Vertical asymptotes are x-values where the denominator of a fraction is equal to 0. To find the vertical asymptote, we need to set the denominator equal to 0 and solve for x. This will give us the x-values where the graph of the function has a vertical asymptote. Removable discontinuities are x-values where the numerator of a fraction is equal to 0. To find the removable discontinuity, we need to set the numerator equal to 0 and solve for x. This will give us the x-values where the graph of the function has a removable discontinuity. In both cases, once we have the x-values, we can plot the graph of the function and see where the vertical asymptote and removable discontinuity are located.
