0,375 has three numbers after a decimal so we will multiply and divide 0,375 by 1000

-439 is the value which is equivalent to (s circle t) (negative 7).

Given,

s(x) = 2 - x²

t(x) = 3x

We have to find the value which is equivalent to (s circle t) (negative 7)

That is,

(s circle t) (negative 7) : This is a notation for compound function.

A function that takes another function as an argument is referred to as a compound function.

s(t(-7)) is the alternative notation for this compound function, which means that the value obtained from the function t(-7) will be used in the function s. (x).

Now, let's calculate the value of t(-7):

That is,

t(x) = 3x

t(-7) = 3 × (-7) = -21

Next, apply the value of t(-7) for s(x)

That is,

s(x) = 2 - x²

s(t(-7)) = s(-21) = 2 - (-21)^2 = 2 - 441 = -439

That is, -439 is the value which is equivalent to (s circle t) (negative 7).

The transformation applied to the parent function is vertical compression by a factor of 0.25.

In mathematics, functions can be manipulated algebraically to obtain graphs of functions through certain transformations. Such transformations are reflections of the x-axis or the y-axis. To flip a function f(x) on the x-axis, multiply the whole function by a negative value to get -f(x), and to flip a function f(x) on the y axis, f(-x ), specify the x variable with a negative value.

Vertical compression helps shrink features vertically. Vertical compression occurs when you multiply the function by a rational scaling factor. The base of the function graph remains the same even when the graph is compressed vertically. Only initial values are affected.

It is vertically compressed by a factor of 0.25.

The conditional probability formula for P(B | A) has been derived from two dependent events P(A and B).

When the outcome from one event influences the outcome of the other, two events are referred to as dependent.

Derivation of conditional probability from two dependent events P(A and B) is-

The probability multiplication rule is used to derive the conditional probability formula, P(A and B) = P(A)×P(B|A).

This rule is also known as P(AB). The Union symbol (∪) represents "and," as in event A occurring and event B occurring.

Step 1: Write the multiplication rule down:

           P(A and B) = P(A)*P(B|A)

Step 2: P(A) divides both sides of the equation:

           P(A and B) / P(A) = P(A)*P(B|A) / / P(A)

Step 3: On the right side of the equation, cancel P(A):

           P(A and B) / P(A) = P(B|A)

Step 4: Rewrite the equation as follows:

           P(B|A) = P(A and B) / P(A)

Therefore, P(B | A) conditional probability formula is compiled from two dependent events P (A and B).

For the parallelogram NELR, we get the value of x as 7°.

We are given a parallelogram NELR.

We know that , the adjacent angles of a parallelogram are supplementary.

So, we get that:

∠ N + ∠ E = 180°

Substituting the values, we get that:

7 x + 33 + 11 x + 21 = 180

18 x + 54 = 180

18 x = 180 - 54

18 x = 126

x = 126 / 18

The sum of the given finite series is 75

The given series is:

[tex]\sum\limits^{10}_{n=5} {(20-n)}}[/tex]

To find the sum of this series,

Expand the summation notation by using the properties of sum operator:

Σ(a+b) = Σa + Σb

Hence,

[tex]\sum\limits^{10}_{n=5} {(20-n)}=\sum\limits^{10}_{n=5} {20}-\sum\limits^{10}_{n=5} {n}[/tex]

If a is a constant, then Σa = k. a, where k is the number of terms = upper limit - lower limit + 1

Using this property:

Using Gaussian elimination, the solution to the given system of equations is given as follows:

x = 5, y = -11, z = 3.

A system of equations is when multiple variables are related, and equations are built to find the values of each variable, according to the relations given in the problem.

For this problem, the equations are given as follows:

(I suppose there was a typing mistake on the first equation, as Gaussian elimination can only be applied to solve linear systems).

For Gaussian elimination, the first step is building the matrix of the system, in which:

Hence, the matrix of the system is given as follows:

[tex]\left[\begin{array}{cccc}2&-1&4&33\\1&2&-3&-26\\-5&-3&5&23\end{array}\right][/tex]

Then, we need to make the coefficient of x zero in the second and third rows, hence:

Then the matrix will be given by:

[tex]\left[\begin{array}{cccc}2&-1&4&33\\0&5&-10&-85\\0&-11&30&211\end{array}\right][/tex]

Now we need to make the coefficient of y on the third row zero, hence:

R3 -> 11R2 + 5R3.

Then:

[tex]\left[\begin{array}{cccc}2&-1&4&33\\0&5&-10&-85\\0&0&40&120\end{array}\right][/tex]

From the third row, we have that:

40z = 120

z = 120/40

z = 3.

From the second row, we have that:

5y - 10z = -85

5y - 30 = -85

5y = -55

y = -11.

From the first row, we have that:

2x - y + 4z = 33

2x + 11 + 12 = 33

2x = 10

x = 5.

Hence the solution of the system is given by:

x = 5, y = -11, z = 3.

If Lee is laying out a design for the tiles of a section of his bathroom floor and he will use 1 white tile for every 6 black tiles to have a total of 28 tiles in the design then the number of white and black tiles Lee will use is equal to 4 and 24 respectively.

The number of white and black tiles Lee will use can be determined by using an algebraic expression.

As 1 white tile is used for every 6 black tiles, an algebraic expression can be represented as,

x + 6x = 28

By solving the value of x, the number of each type of tile that Lee will use can be calculated,

x + 6x = 28

7x = 28

x = 28 ÷ 7

x = 4

As there is one white tile for every six black tiles,

White tiles = 1(x) = 1(4) = 4

Black tiles = 6(x) = 6(4) = 24

Hence the number of white tiles Lee will use is equal to 4 and the number of black tiles Lee will use is equal to 24.

For the given situation, we can clearly say that the change in one quantity will cause a change in the second quantity as well.

Correlation is a relationship between the values ​​of two variables. A scatter plot is a useful tool for displaying data about two variables as a series of points in the x and y plane and determining whether there is a correlation between the variables.

Causality means that one event causes another. Causality can only be determined by well-designed experiments. In such experiments, similar groups receive different treatments, and the results of each group are examined.

From the above information, we concluded that a person's age and the number of cassette tapes he/she owns are correlated more he lives the more he buys the cassette tapes. So we can make relation from this,

Person's Age ∝ Number of Cassette

This clearly states that by increasing/changing one quantity we will increase/change the other quantity as well.

Similarly, now that they have a direct relation if we decrease the Age of the person, the number of Cassette's will also decrease. A positive correlation we can call it.

Answer:

15y+14

Step-by-step explanation

Answer: 14 + 15y

Step-by-step explanation:

E = Eileen’s age = 3y

M = Mum’s age

Total Age = 14 + 3y + 4(3y)

                =  14 + 15y

Total age in 7 years time is their current ages plus 7 years for each (14 years)

Eileen is 3y, and her mum is 4 times that, which is 12y, meaning that their total ages are 3y + 12y, or, 15y.

Total age is then 15y + 14. Since we don’t know what y equals, we cannot add these two terms, and we can just leave them like that!

So, the answer is 14 + 15y.

The equation in slope-intercept form for the line that passes from the points (-7,2) and (5,8) is y = (1/2)x -3/2.

We know that, the slope intercept form is given by:-

y = mx + b

Where,

(x,y) is the ordered pair of every point on the line

m is the slope of the line

b is the y-intercept of the line

We know that, slope = (8-2)/(5-(-7)) = 6/12 = 1/2

Putting (-7,2) in (x,y) and m = 1/2 in the slope intercept form, we get,

2 = (1/2)(-7) + b

2 = -7/2 + b

b = -3/2

Hence, the slope intercept form of the line is y = (1/2)x -3/2.

A circle is a curve sketched out by a point moving in a plane. The diameter and circumference of the circle are (x/4) units and (x/4)π units, respectively.

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the center.

Given that radius of the circle is x/8 units. Therefore, the diameter and the circumference of the circle can be written as,

Diameter of circle = 2 × (Radius of the circle)

                             = 2 × (x/8) units

                             = x/4 units

Circumference of circle = 2 × π × (Radius of the circle)

                                       = 2 × π × (x/8) units
