which one of the following entries from the output tables of a multiple regression model could be used to reject the null hypothesis of equal coefficients in the global test?

In solving the equation, the student did the division wrong, and 29.4/4.2 = 7 which is correct.

Multiplication is the opposite of division.

If 3 groups of 4 add up to 12, then 12 divided into 3 groups of equal size results in 4 in each group.

Creating equal groups or determining how many people are in each group after a fair distribution is the basic objective of division.

So, the equation is:

4.2p = 29.4

Let's solve as follows:

4.2p = 29.4

p = 29.4/4.2

p = 7

So, the value of p comes to 7.

Where in the image, the value of p is 123.48 which is wrong as the division is not done properly.

Therefore, in solving the equation, the student did the division wrong, and 29.4/4.2 = 7 which is correct.

The value of x = -84/17, y= 24/17 and z = 9/17

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

x -2y + z= -6

x- 5z= -12

-x+ 6y + 4z = 3

Put x= -12+ 5z in equation 1 and 3

-12+ 5z - 2y + z= -6

6z - 2y = 6

3z - y= 3............(a)

and, 12 - 5z + 6y + 4z = 3

6y - z = -9.......(b)

Solving a and b we get

6(3z- 3) - z = -9

18z - 18 - z= -9

17z = 9

z= 9/17

x and y are the legs.

[tex]5\sqrt{2}[/tex] is the hypotenuse.

The hypotenuse is always opposite the 90 degree angle.

The hypotenuse is always the longest side of any right triangle.

After solving the angles, the measure of angle x is 145°.

When two straight lines or rays intersect at a single endpoint, an angle is created.

The vertex of an angle is the location where two points come together.

The Latin word "angulus," which means "corner," is where the term "angle" originates.

The names of fundamental angles include acute, obtuse, right, straight, reflex, and full rotation.

A geometrical shape called an angle is created by connecting two rays at their termini.

In most cases, an angle is expressed in degrees.

(Refer to the image attached below)

We can see that ∠ABC is a straight angle.

∠ABC = ∠ABD + ∠DBC where ∠ABD is x.

Now, solve for x as follows:

∠ABD + ∠DBC = ∠ABC

x + 35 = 180

x = 180 - 35

x = 145°

Therefore, after solving the angles, the measure of angle x is 145°.

Answer:

To find the value of the quartiles, we need to first find the median of the data set. The median is the middle value of the data set, or the value that separates the lower half of the data from the upper half. In this data set, the median is 2.5, as it is the middle value when the data is arranged in ascending order.

Once we have the median, we can find the first and third quartiles. The first quartile, also known as Q1, is the median of the lower half of the data set, and the third quartile, also known as Q3, is the median of the upper half of the data set. In this data set, the lower half of the data is {1.3, 1.5, 1.7, 2, 2.5}, and the upper half of the data is {2.7, 2.9, 3, 3.1}. The median of the lower half is 1.7, and the median of the upper half is 2.9.

Therefore, the value of the quartiles is Q1 = 1.7, Q2 = 2.5, and Q3 = 2.9.

Option C, Q1 = 1.7; Q2 = 2.5; Q3 = 2.9, is the correct answer.

The measures of two angles in the order from the smallest to the greatest are 21° and 69°.

What is a right triangle?

A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or formerly rectangle triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.

Given the acute angle of a right triangle is 6 more than 3 times the measure of the other small angle.

Assume that the measurement of smaller angle is x.

Then the mathematical expression of 6 more than 3 times of x is 6 + 3x.

The measure of third angle is 90° since it a right triangle.

The sum of all interior angles of a right triangle is 180°.

The equation is

x + (6 + 3x) + 90 =180

x + 6 + 3x + 90 =180

Combine like terms:

(x + 3x) + (6 + 90) = 180

4x + 96 = 180

Subtract 96 from both sides:

4x = 180 - 96

4x = 84

Divide both sides by 4

x = 21

Putting x = 21 in the expression (6 + 3x) :

6 + 3x = 6 + 63 = 69.
