A polynomial equation of the second degree, or a quadratic, must contain at least one squared term to be considered a quadratic.

Quadratic equations or quadratic functions. A polynomial equation of the second degree, or a quadratic, must contain at least one squared term to be considered a quadratic. Equations using quadratics is another name for it. The quadratic equation is expressed in its general form as ax2 + bx + c = 0.

For instance, 6x2 + 11x - 35 = 0, 2x2 - 4x - 2 = 0, 2x2 - 64 = 0, x2 - 16 = 0, x2 - 7x = 0, 2x2 + 8x = 0, etc. are examples of quadratic equations.

Three kinds of quadratics are frequently employed:

Standard Form: y = an x 2 + b x + c y = an x 2 + b x + c

y = a (x r 1, x r 2) is the factored form. y=a(x-r 1)(x-r 2) y=a(x−r1)(x−r2)

Vertex Formula: y=a (x h) 2 + k y=a (x-h)2 + k y=a (x-h) 2+k.

True. A data model is an abstract representation of the data structures used in a database.

It is typically used to represent the structure of the data and the relationships between different elements of the data. Data models are used to define the structure of the data in a database, as well as the relationships between different elements of the data. A data model is a combination of entities, attributes, relationships, and constraints. It is used to describe the data that is stored in a database and how the data can be accessed and manipulated. The data model also defines the relationships between the different elements of the data, such as which element of the data is related to which other element. The data model also defines the constraints that must be met in order to ensure the integrity of the data. A data model is also used to define the data types that are used in the database and the operations that can be performed on the data. For example, a data model may define data types such as integers, strings, and dates, as well as operations such as arithmetic, comparison, and sorting. A data model also defines rules for the structure and organization of the data, such as which fields must be present in a record, the order in which records must be stored, and the types of relationships that can exist between records.

Answer:

the probability of randomly selecting the chair and the vice chair is 10%.

Step-by-step explanation:

There are a total of 5 members on the health services committee, and 2 of them will be chosen to serve as the chair and vice chair, respectively.

The probability of randomly selecting the chair out of the 5 members is 2/5, or 40%.

Once the chair is selected, there are 4 members remaining, and only one of them can serve as the vice chair. Therefore, the probability of randomly selecting the vice chair out of the remaining 4 members is 1/4, or 25%.

To find the probability of randomly selecting the chair and the vice chair, we need to multiply the individual probabilities of selecting each position, which is (2/5) * (1/4) = 2/20 = 1/10 = 10%.

So, the probability of randomly selecting the chair and the vice chair is 10%.

Take the original data and divide it by the standard deviation to determine the z-scores. X is a symbol for the relevant data point. For the population from which you selected your sample, mu and sigma stand in for the mean and standard deviation.

In terms of standard deviations above or below the mean, a data point's z-score quantifies this exact distance.

A z-score is calculated using the following formula:

data point = mean standard deviation

Data point means with standard deviation equal to z

The same equation is given below in symbol form:

z=  x−μ / σ

Some significant z-score details are as follows:

An elevated z-score indicates that the data point is.

When a data point has a negative z-score, it is below average.

The data point is considered to be roughly average if the z-score is near to 0.00.

If a data point's z-score is higher or lower than 3 33 or 3 3minus, the data point is deemed uncommon.

At Almond, the average score on a history midterm is

= 85 = 85mu, which is equivalent to 85 with a standard deviation of

= 2 = 2 = 2 = 2 = 2 = 2 = 2 = 2

On the test, Michael received a score of 86.866.668.

Calculate Michael's exam grade in Z-score form.

His Grade = Mean Grade Standard Deviation

= 86 − 85 / 2

= 1 /2 = 0.5 z z z

= standard deviation of his grade and mean grade.

= 2 / 86−85

= 2 / 1 =0.5.

The z-score for Michael is 0.5, 0.50, and 5. He received a grade that was half a standard deviation higher than the mean.

Step-by-step explanation:

3.3 as a fraction is 3 3/10. The first 3 is a whole number because it is to the left of the decimal point, and it represents 3 ''ones''. However, the second 3 to the right of the decimal point represents a decimal amount. Because this 3 is in the tenths place, we say it as ''3 tenths.

We can conclude that the division property of equality was done between step 4 and step 5.

What is linear equation ?

Linear equation can be defined as the equation in which the highest degree is one.

The Division Property of Equality states that when both sides of an equation are divided by the same nonzero number, both sides remain equal.

That is, if a, b, and c are real numbers such that a = b and c ≠0, then  

a/c = b/c

At step 4: The equation was -6x = 57

To move to step 5, Paula had to divide both sides by the co-efficient of x (-6) in order to get the value of x. See below

-6x = 57

---- Divide both sides by -6 (Step 4)

-6x / -6  = 57 / -6

---- (Intermediary between step 4 and 5)

x = -9.5

----- Step 5

Hence, we can conclude that the division property of equality was done between step 4 and step 5

What is meant by three-dimensional space?

A three-dimensional space in geometry is a mathematical structure where a point's location depends on three different values.

For this question, we are considering the east of origin as the positive x-axis, the above origin as the positive z-axis and the north of the origin as the positive y-axis.

a)  For the first hook there is no y-axis, it is hung in the xz plane.

So the coordinates are (4,0,7.5)

b) The second hook coordinates are given as (5, 12,8)

c) The point on the string which joins the hook, which is halfway between the hooks can be found using the mid-point formula.

x= (x1 + x2)/2 = (4+5)/2 = 4.5

y = (y1 + y2) /2 = (0+12) / 2 = 6

z = (z1+z2) / 2 = (7.5 + 8) /2 = 7.75

The area in square feet of the part of the backyard in which Shayne is allowed to dig is option D: 272 ft².

What is area?

An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.

The length of the rectangle ADEH is 17 ft.

The breadth of the rectangle ADEH is 22 ft.

The length of the rectangle ABGH is 17 ft.

The breadth of the rectangle ABGH is -

GH = (EH - GE)

GH = [EH - (GF + EF)]

GH = [22 - (6 + 14)]

GH = [22 - 20]

GH = 2 ft

The formula for the area of a rectangle is -

Area = Length × Breadth

The area of part where Shayne is allowed to dig is -

Area = [Area of ABGH + Area of CDEF]

Area = [(17 × 2) + (17 × 14)]

Area = [34 + 238]
