The z-score corresponding to a score that is 12 points above the mean is 2.

The z-score is a numerical measurement used in statistics to determine the sample data value's relationship to the mean of a group of values, measured in terms of standard deviation from the mean. It is measured as the difference of the sample data value and the sample mean over the standard deviation, such that

z-score = (x – μ) / σ

where x = sample data value

μ = mean

σ = standard deviation

If the sample score is 12 points above the mean, then (x – μ) = 12.

(x – μ) = 12

σ = 6

Substitute the values to the z-score formula.

z-score = (x – μ) / σ

z-score = 12/6

z-score = 2

hello

the question presented here related to compound interest and we can solve that using the formula

let's proceed to substitute the values into the equation

the compounded interest compounded monthly at 6% for 5 years is 3375

The amount is  3250

The accumulated amount is calculated using the initial investment and  interest earned in the given duration

The formula for simple interest is  P×R×T and further, it is divided  by 100

SI= 2500 ×  6 × 5 =75000 ÷100 = 750

Now, for calculating the accumulated amount we will add the initial investment and the interest gained

ie, 2500+750 =3250

Here we are using the simple interest method to calculate the interest as it is assumed to be taken as simple interest when nothing is specified.

Step-by-step explanation:

The true statement is Quadrilateral WXYZ can be mapped onto quadrilateral MATH using a sequence of rigid motions.

The triangles are said to be congruent when two angles and a non-included side of one triangle match the corresponding angles and sides of another triangle.

Given:

MATH is congruent to quadrilateral WXYZ.

Then congruent sides are

MA= WX

AT = XY

TH = YZ

and, congruent angles are

<M = <W

<A = <X

<T= <Y

<H = <Z

So, if the quadrilateral is congruent then they equal in measure.

Hence, the true statement is  Quadrilateral WXYZ can be mapped onto quadrilateral MATH using a sequence of rigid motions.

The image of the function after the translation is g(x) = 6x - 4

Translation involves shifting a function across the coordinate plane

The given parameters are:

f(x) = 6x + 2

The transformation is given as

Translation 6 units down

Mathematically, this transformation can be represented as

(x, y) = (x, y - 6)

When represented as a function, we have

g(x) = f(x) - 6

Substitute the equation f(x) = 6x + 2 in the equation g(x) = f(x) - 6

So, we have the following equation

g(x) = 6x + 2 - 6

Evaluate the like terms

g(x) = 6x - 4

Hence, the equation of g(x) is g(x) = 6x - 4

Answer: b + 24 = 68

Step-by-step explanation:

we are told the zoo has 68 different species of birds so the equation will be = 28. The answers showing = 24 are already wrong.

transported means they are taken away, so we have to subtract 24 (animals that stayed in the zoo) to find b which are the remaining species moved to the barn.

b + 24 = 68
  -  24    -24

b = 44 (transported to the barn)
     24 ( stayed in the zoo)
    68 ( total number of species of birds)

The correct expression to show the species of transported birds will be;

⇒ b + 24 = 68

Where, b is the number of transported birds.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Total number of birds in Roaring Zoo = 68

Number of stayed birds in Zoo = 24

Let number of transported birds = b

Then, We can formulate;

Total number of birds = Stayed birds + Transported birds

Substitute all the values, we get;

⇒ 68 = 24 + b

Therefore,

The correct expression to show the species of transported birds will be;

⇒ b + 24 = 68

Where, b is the number of transported birds.

Yes, this is a valid argument. This argument uses the Law of Detachment.

The Law of Detachment states that if the hypothesis of a true conditional statement is true, then the conclusion must be true as well. The Law of Detachment is the most often employed deductive reasoning theory.

Given:

Points X and Y both lie on plane R.

Conclusion: Points X and Y are coplanar.

The argument is true because,

The term "coplanar" refers to "being on the same plane." Coplanar points are points that are on the same plane. A group of points in space is said to be coplanar if there is a geometric plane that contains all of them.

The relation is the relationship between two or more sets of values. Suppose, x and y are two sets of ordered pairs. If set x has a relation with set y, then the values of set x are called domain whereas the values of set y are called range. A relation from a set A to a set B is a subset of A×B. Hence, a relation R consists of ordered pairs (a,b), where a∈A and b∈B. If (a,b)∈R, we say that is related to, and we also write aRb. A connection between the elements of two or more sets is a relation. The sets must be non-empty. A subset of the Cartesian product also forms a relation R. A relation may be represented either by the Roster method or by the Set-builder method.

The farmer has 28 cows from a total of 80 animals in the farm.

Each chicken has two legs and each cow has four legs. The farmer has a total of 216 legs among all the animals, which are 80. Then, we can represent the situation with the following system of linear equations:

x + y = 80

4 · x + 2 · y = 216

Where:

The system can be solved easily by some algebraic handling:

x = 80 - y

4 · (80 - y) + 2 · y = 216

320 - 4 · y + 2 · y = 216

320 - 2 · y = 216

2 · y = 320 - 216

2 · y = 104

y = 52

x = 80 - 52

x = 28

Based on the straight line being parallel to the line, L1, and the gradient, the equation of the straight line L2 is y = 2x - 5

The equation of a straight line takes the form:

b = y - intercept

The slope is the same as the gradient and parallel lines have the same gradient. The gradient of L2 is therefore 2 as well.

Writing 1 trillion in scientific notation is 1 × 10^12.

A scientific notation simply means the way of expressing numbers that are either too large of too small. Scientific notation is a method of expressing numbers that are either too large or too little to be represented in decimal form. In the United Kingdom, it is known as scientific form, standard index form, or standard form.

Scientific notation is a method of displaying very large or very small numbers in a more simplified format. We know that entire numbers can be extended indefinitely, but such large numbers cannot be written on a piece of paper. Furthermore, the numbers in the millions place after the decimal required to be represented in a simpler format. As a result, representing a few integers in their expanded form is challenging. As a result, we employ scientific notation.

In this case, I trillion is written as 1,000,000,000,000.

Therefore, it has 12 zeros.

The scientific notation is 1 × 10^12.
