True, Field X is a dependent function on Field Y if the value of Field X depends on the value of Field Y.

In relational database theory, a dependent function is a constraint between two sets of objects related to a database. In other words, the dependency function is the boundary of two behaviors in a relationship. FD: The productivity function X → Y is called trivial if Y is part of X. In other words, the FD:X → Y dependency means that the value of Y is determined by the value of X. Two bunches of X values ​​that share the same thing must have the same Y value where Z = U - XY is the residue. In simple terms, if the values ​​of the X attributes are known (assuming they are x), then the values ​​of the Y attributes corresponding to x can be determined by looking at them in an R tuple containing x. Usually, X is called the determinant set and Y is called the correlation set. The efficient function FD: X → Y is said to be trivial if Y is part of X.

Answer:

2 x 7

Step-by-step explanation:

4 x 7 = 28

Since you want doubled, we have to half to find start.

28/2 = 14

Only solid equation that equals 14 is 2 x 7

And since 4 is a double of 2, the answer checks out

The multiplication fact that can be doubled to find 4 x 7 is

2 x 7.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

4 x 7 = 28

Now,

The multiplication of 2 x 7 = 14.

If 2 x 7 is double we get,

2 x (2 x 7) = 2 x 14 = 28

Thus,

The multiplication fact is 2 x 7.

The graph for the linear equation y=24x, will be a straight line having coordinate (1,24) i.e. B.

What is a linear equation, exactly?

A linear equation is a first-degree algebraic equation in which each term is either a constant or the product of a constant and a single variable (degree 1). A linear equation is stated as y = mx + b, where y is the dependent variable, x is the independent variable, m is the line's slope, and b= y-intercept .

A linear equation's graph is a straight line. The line's slope decides how steep it is, and the y-intercept indicates where the line crosses the y-axis. Linear equations are used to model relationships between variables that are directly proportional to each other, such as distance and time, or cost and quantity.

Now,

Given equation is y=24x

then for  x,    y is

              1,    24

              2,   48

              3,    72

              4,     96

Hence, the graph will be as represented in option 2.

Step-by-step explanation:

4 quarts for 12 square yards means the constant of proportionality is 3 square yards per quart.

  y = 3·5 = 15

Mona can clean 15 square yards with 5 quarts.

The quilter wants to make a design using the Golden Ratio, specifically focusing on the ratio of triangle heights. To find the height ratio, we can use the properties of the Golden Ratio.

The Golden Ratio is a mathematical concept where two quantities are in proportion if their ratio is equal to the ratio of their sum to the larger of the two quantities. Mathematically, it can be represented as (a + b) / a = a / b, where a is the larger quantity and b is the smaller quantity.

In this case, the quilter wants to find the ratio of triangle heights. Let's assume the height of the larger triangle is a and the height of the smaller triangle is b. According to the Golden Ratio, we have (a + b) / a = a / b.

To solve for the height ratio, we can cross-multiply and simplify the equation. We get a^2 + ab = a^2, which simplifies to ab = a^2 - a^2, or ab = 0.

Since ab = 0, we can conclude that the height ratio of the triangles is 0. This means that the height of the smaller triangle is 0, while the height of the larger triangle can be any positive value.

In summary, when using the Golden Ratio to determine the ratio of triangle heights, the ratio is 0.

The reasoning of Percy is incorrect because there is one mode for the data set.

Mode of a data set is the value that occur most frequently in a data set.

There may be no mode, one mode or more than one mode for a data depending on the number of times values are repeating.

Given data is {5, 0, 4, 0, 0}.

Here the value 0 is repeating three times.

No other number has repeated three times.

So there is only one mode for the data set and is 0.

This does not mean that there is no mode for the set.

A data set has no mode if and only if all the numbers in the set are repeated same number of times.

Answer:

A) 10

B) (C+10)/2 = n

Step-by-step explanation:

A) We know that the total cost is represented by the variable C. So, basically the problem is saying that the variable C is equal to 30. If we plug that into the equation, we get 30 = 2n + 10. Solving this, we get n = 10.

B) Isolating a variable means to only have the specified variable on one side and have all other integers and variable on the other side. So, the final answer would be (C+10)/2 = n.

The value of the fraction 2/3 × 5/8 isn't 3/4 because it is 10/24 and reducing to lowest term won't give 4.

A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers

The value of the fraction will be:

Answer:

c. 122.1 cm

Step-by-step explanation:

so l * w + \(\frac{\pi r^2}{2}\)

since 6 cm is the diameter

6/2 = 3

the radius (or r) is 3

so 18 * 6 + \(\frac{3.14 * 3*3}{y}\)

108 + \(\frac{3.14*9}{y}\)

108 + \(\frac{28.26}{2}\)

108 + 14.13 = 122.13

simplified: 122.1 cm

hope this helps:)

Answer:

C. 122.1

Step-by-step explanation:

The area of a semicircle is HALF of the area of the circle. As the area of a circle is \(\pi r^2\). So, the area of a semicircle is \(\frac{1}{2}(\pi r^2)\), where r is the radius.

18 × 6

= 108

108 \(cm^2\) is the area of the rectangle,

For the semicircle, we know the diameter is equal to 6 cm,

(Remember that Diameter is equal to the radius times 2 (r × 2)),

To find the radius, divide the diameter by 2,

6 ÷ 2

= 3

The radius of the semicircle is 3 cm

Now use the equation \(\frac{1}{2}(\pi r^2)\) to find the area of the semicircle,

\(\frac{1}{2} (\pi 3^2)\)

(Remember pie is 3.14...)

Slove:

\(\mathrm{Remove\:parentheses}:\quad \left(a\right)=a\)

\(=\frac{1}{2}\pi 3^2\)

\(\mathrm{Multiply\:fractions}:\quad \:a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}\)

\(=\frac{1\pi 3^2}{2}\)

\(\mathrm{Multiply:}\:1\pi =\pi\)

\(=\frac{3^2\pi }{2}\)

\(3^2=9\)

\(=\frac{9\pi }{2}\)

\(\frac{9\pi }{2} =\left(\mathrm{Decimal:\quad }\:14.13716\dots \right)\)

Now take the decimal 14.13716.... and round to the nearest tenth,

14.13

(Remember 4 or less keep it the same, 5 or more bring the value up one more)

3 less than 5 so keep the 1 the same,

14.1

Now add 108 and 14.1,

108 + 14.1

= 122.1

Therefore the total area of the shape is 122.1 \(cm^2\). Answer ⇒ C.

A graph of the equation y = 2x + 3 is shown in the image attached below.

In order to use the given linear function to complete the table, we would have to substitute each of the values of x (x-values) into the linear function and then evaluate as follows;

When the value of x = -2, the linear function is given by;

y = 2x + 3

y = 2(-2) + 3

y = -1.

When the value of x = -1, the linear function is given by;

y = 2x + 3

y = 2(-1) + 3

y = 1.

When the value of x = 0, the linear function is given by;

y = 2x + 3

y = 2(0) + 3

y = 3.

When the value of x = 1, the linear function is given by;

y = 2x + 3

y = 2(1) + 3

y = 5.

When the value of x = 2, the linear function is given by;

y = 2x + 3

y = 2(2) + 3

y = 7.

When the value of x = 3, the linear function is given by;

y = 2x + 3

y = 2(3) + 3

y = 9.

El precio de la falda es 50 €.

Step-by-step explanation:

Lo que sabemos:

\( F = 5 + B \)   (1)

En donde F es por falda y B por blusa.

Si compras 6 faldas y 4 blusas y pagas 480 €:

\( 6F + 4B = 480 \)  (2)

Entonces, al introducir la ecuación (1) en (2) podemos hallar el precio de cada falda.

\( 6F + 4B = 480 \)

\(6(5 + B) + 4B = 480\)

\( 10B = 480 - 30 \)

\(B = \frac{450}{10} = 45\)  

Finalmente, el precio de la falda se puede encontar con la ecuación (1):

\(F = 5 + 45 = 50\)

Por lo tanto, el precio de la falda es 50 €.
