We have a line with slope -1 and y-intercept of 8.

We can write the equation of this line as:

Then, we can test the values for each x-coordinate and see if it matches the y-coordinate indicated by the point:

Point (3,5)

Point (2,10)

Answer: the point (2,10) is not on the line.

Answer:

m∠FGD = 132°

Step-by-step explanation:

Corresponding Angles Postulate

When a straight line intersects two parallel straight lines, the resulting corresponding angles are congruent.

Therefore, as AB is parallel to CD, and line EH intersects them:

⇒ m∠EFB = m∠FGD

Substitute the given expressions for the angles and solve for x:

⇒ (3x - 120)° = (x + 48)°

⇒ 3x - 120 = x + 48

⇒ 3x - 120 - x = x + 48 - x

⇒ 2x - 120 = 48

⇒ 2x - 120 + 120 = 48 + 120

⇒ 2x = 168

⇒ 2x ÷ 2 = 168 ÷ 2

⇒ x = 84

Substitute the found value of x into the expression for m∠FGD:

⇒ m∠FGD = (84 + 48)°

⇒ m∠FGD = 132°

The general binomial theorem can be expressed as:

Now, for this problem we identify:

(a)

Then, using the general form:

The combination operator for this sum:

Then, the simplified terms of the expansion are:

Given three numbers x, y and z

The average of the numbers = A

We will complete the given table

When : x = 7 , y = 12 , z = 8

When x = 23 , y = 17 , z = 2

For the last case,

x = 4 , y = 11 , A = 6

Solve for z, multiply both sides by 3

Correct option is D. Since sample size is 10, the sample size is not adequate, the conclusion is likely to be untrue.

The process of deciding how many observations or replicates to include in a statistical sample is known as sample size determination. Any empirical study with the aim of drawing conclusions about a population from a sample must take into account the sample size as a crucial component.

The quantity of completed survey replies is known as the sample size. Because it merely reflects a portion of the target population (or set of people whose ideas or behavior you are interested in), it is known as a sample.

The equation reads Sample Size = N / (1 + N*e2), where N is the population size.

Be aware that this is the least desirable and least precise formula.

The answer is the third option.

The height of the object based on the information is 1963 feet.

It should be noted that a function is important to show the relationship between the variables given in the data.

In this case, the function given for the height of the object is given as:

h = 16t² + 1899

where t = time

When the time is 2 seconds, the height will be:

h = 16t² + 1899

h = 16(2)² + 1899

h = 64 + 1899

h = 1963

The height is 1963 feet.

The value of x based on the multiplication in 90 × x = 9000 is 100.

Multiplication simply means the product of numbers given. This is illustrated with the sign given as ×.

In this case, 90 × x = 9000

Multiply 90 by x which equates to 9000

90x = 9000

Divide by 90

90x / 90 = 9000 / 90

x = 100

The value of x is 100.

From the information given above, The substitution property is used here. See further explanation below.

The substituted property of equality states that one value may be substituted for another in an expression or equation and the result will be the same.

If the values of x and y are equivalent, then x and y may be substituted for one another. The property's opposite is likewise true.

For exmaple,

If x=y for any real integer x and y, then y may be replaced for x in any statement.

In the above instance, x = 2 and hence can be substituted for x in the first expression given as:

What is an algebraic expression and how is it formed?
Variables and constants are used to create algebraic expressions using a variety of techniques. It is a mathematical expression made up of terms and includes variables, constants, and algebraic operations like addition, subtraction, etc. When operations like addition, subtraction, multiplication, division, etc. are performed on any variable, the resulting equations are called algebraic expressions. An algebraic expression (or variable expression) is a grouping of terms that have undergone operations like addition, subtraction, multiplication, division, etc.

Let the given number be = n
Therefore, nine times the number = 9n
Also, six times the number = 6n
Again, one more than six times the number = 6n + 1
Given, difference between nine times a number and one more than six times the number.
