The midpoint of the line segment is (1, 2). Then the correct option is B.

Let AB be the line segment and C be the mid-point of line segment AB. Let the coordinate of point A (x₁, y₁), the coordinate of point B (x₂, y₂), and the coordinate of the mid-point (x, y).

Then the coordinate of the mid-point of the line segment is given as,

(x, y) = [(x₁ + x₂) / 2, (y₁ + y₂) / 2]

The endpoints of the line segment are (-1, 7) and (3, -3). Then the mid-point of the line segment will be given as,

(x, y) = [(-1 + 3) / 2, (7 - 3) / 2]

(x, y) = (2/2, 4/2)

(x, y) = (1, 2)

The midpoint of the line portion is (1, 2). Then the right choice is B.

No, there isn’t enough information because only two pairs of corresponding sides can't be used to prove that two triangles are congruent.

What is congruent?

In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.

Here,

We have to prove whether ΔABC and ΔDCB can be proven congruent.

For this, we examine the given diagram and concluded that there isn’t enough information because only two pairs of corresponding sides can't be used to prove that two triangles are congruent.

a) The probability of rolling a total of 5 is 1/9.

b) If a pair of fair dice 360 times, then 40 times you will get a total of 5.

What is probability?

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

The number of 5 in the table is 4.

The total number of outcomes is 6 × 6 = 36

The number of outcomes of favorable event is 4.

Total number of outcomes is 36.

The probability getting total of 5 after rolling the pair of dice is

=4/36

Divide the denominator and numerator by 4:

= 1/9

If 360 time the pair of dice rolled, the number of times to get total 5 is

360 × (1/9)

= 40.

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.

                                  Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

The domain of the function = The possible number of flower arrangements

that can be sold

The possible number of flower arrangements that can be sold = Whole

numbers from 0 to 25

Therefore;

The possible number of flower arrangements that can be sold = 0 ≤ x ≤ 25

Where;

x = An integer

Which gives;

The domain of the function, D = {0 ≤ x ≤ 25 | x ∈ Z}

The equation for the given linear function is y = 12m + 20.

A linear equation in two variable has the general form as y = ax + by + c, where a, b and c are integers and a, b ≠ 0.

It can be represented as a straight line on a graph.

The given points for the linear function are (2, 44) and (5, 80) respectively.

The slope can be obtained as,

m = (80 - 44)/(5 - 2)

   = 36/3

   = 12

Substitute the value of m in the general form y = mx + c to obtain,

y = 12x + c

Now, substitute x = 2 and y= 44 in the above expression as,

44 = 12 × 2 + c

=> c = 44 -24

=> c = 20

Thus the linear function can be written in the form of equation as,

y = 12m +  20

Hence, the equation of the function for the given case is y = 12m + 20.

The zeros of a polynomial function is the the value of x when the function is equal to zero

The zero is also called the root of the polynomial

To find the polynomial we equate to the zeros

the first

x = 5

x - 5 = 0

the second

x = -5

x + 5 = 0

the third

x = 5i

x - 5i = 0

the fourth

x = -5i

x + 5i = 0

Bringing the terms together

(x - 5) (x + 5) (x - 5i) (x + 5i)

In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.

Th value of the equation f ( x ) is given as

when x = 0 , f ( 0 ) = 5

when x = 1 , f ( 1 ) = 7

when x = 5 , f ( 5 ) = 15

What is an Equation?

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.

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 data ,

Let the equation be represented as A

Now , the value of A is given as

f ( x ) = 2x + 5

Now , the values of the function f ( x ) can be determined when we substitute for the values for x in the equation

So , in order to find f ( 0 ) , substituting the value for x as x = 0, we will get the value for the function

a)

when x = 0

The equation is f ( x ) = 2x + 5

f ( 0 ) = 2 x 0 + 5

f ( 0 ) = 5

So , the value of f ( 0 ) = 5

b)

when x = 1

The equation is f ( x ) = 2x + 5

f ( 0 ) = 2 x 1 + 5

f ( 0 ) = 7

So , the value of f ( 0 ) = 7

c)

when x = 5

The equation is f ( x ) = 2x + 5

f ( 0 ) = 2 x 5 + 5

f ( 0 ) = 15

So , the value of f ( 0 ) = 15

Therefore , the values of the equations are f ( 0 ) = 5 , f ( 1 ) = 7 , f ( 5 ) = 15

Hence ,

Th value of the equation f ( x ) is given as

when x = 0 , f ( 0 ) = 5

when x = 1 , f ( 1 ) = 7

when x = 5 , f ( 5 ) = 15

The inequality that can be used to determine the number of books, b, Erin must sell in order to meet her goal of making more than $180 in book sales is 12b ≥ 180.

2. The solution to the inequality 12b ≥ 180 is that b ≥ 15.

Inequality is a mathematical statement that two or more mathematical expressions are unequal because their solutions are not equivalent in value.

Inequalities are depicted as less than (<), more than (>), not equal to (≠), less than or equal to (≤), and more than or equal to (≥).

The selling price per book = $12

The total sales revenue expected is ≥ $180

The number of books = b

Inequality describing the situation = 12b ≥ 180

b ≥ 180 ÷ 12
