Answer:

1) A heart is equal to 5 units, a star to 13 units and a square to 20 units.

2) A star is equal to 66 units, a circle to 30 units and a triangle to 14 units.

Herein we find two case of systems of elements which have to be solved on the fact that each element represents a quantity. Now we proceed to represent each system:

Case 1

x - Heart

y - Star

z - Square

The algebraic representation of the system is shown below:

18 - x = y                      (1)

2 · x = 10                     (2)

z - y - 2 = x                  (3)

By (2):

x = 5

By (1):

y = 18 - 5

y = 13

By (3):

z = x + y + 2

z = 5 + 13 + 2

z = 20

Case 2

x - Triangle

y - Star

z - Circle

The algebraic representation of the system is shown below:

2 · x = 28                   (1)

80 - x = y                   (2)

y + x - z = 50             (3)

By (1):

x = 14

By (2):

y = 80 - 14

y = 66

By (3):

z = y + x - 50

z = 66 + 14 - 50

z = 30

The truth value of the statement; If pigs can fly, then 2+5=7   is false.

The term syllogism has to do with logical reasoning. In this case, the premise must lead to the conclusion. The premise is the basis upon which we could draw the conclusion. The truth value of the premise is what determines the truth value of the conclusion as one naturally follows from the other.

Now, in this case we have a conditional statement. Recall that a conditional statement is an if – then statement. The truth value of the premise has an impact on the truth value of the conclusion. We have the statement written in the manner; If pigs can fly, then 2+5=7 .

We know that pigs can not fly. This is a false premise. However, the conclusion that has been given is true by the principle of addition in mathematics. The truth value of the statement is false.

An example of a truth value in which both the premise and the conclusion are true is; If lions are wild animals then lions are one of the animals found in the forest.

The phenomenon that the sampling distribution of the sample mean can be approximated by a normal distribution as the sample size become large is called: Central Limit Theorem.

The central limit theorem (CLT) of probability theory states that, under the assumption that all samples are of equal size and regardless of the population's actual distribution shape, the distribution of a sample variable approaches a normal distribution (i.e., a "bell curve") as the sample size increases.

Now,

As stated in the definition of the Central Limit Theorem, sampling distribution of the sample mean can be approximated by a normal distribution as the sample size become large with the help of the stated theorem.

The measure of angle is 24°.

We are given the two sides of the triangle as:

25 units and 10 units

Since the able that need to be found lies at 25 units side, the base side will be that only.

So, we get that:

Base side = B = 25 units

Perpendicular side = P = 10 units

We know that:

tan θ = P / B

tan θ = 10 / 25

tan θ = 2 / 5

θ = tan⁻¹ ( 2/ 5)

which will be approximately equal to

θ = 24°

Therefore, we get that, the measure of angle is 24°.

Using the equation of a circle, it is found that the value of y is -4.

Equation of the circle:

A circle is a closed curve that is drawn from the fixed point called the center, in which all the points on the curve are having the same distance from the center point of the center.

The equation of a circle with (h, k) center and r radius is given by:

(x-h)² + (y-k)² = r²

Given,

The points (0, 5) and (0, −5) are the endpoints of the diameter of a circle.

The point (3, y) is on the circle, in quadrant 4.

Here we need to find the value of y.

The center is the midpoint of them, thus:

[tex]x=\frac{0+0}{2}=0\\ y=\frac{5-5}{2}=0[/tex]

So, the midpoint is (0,0).

The diameter(twice the radius) is the distance between these two points, so:

[tex]2r=\sqrt{(0-0)^2+(5-(-5))^2}[/tex]

=> 2r = √0+100

=> 2r = √100

=> 2r = 10

=> r = 5

Thus, the equation of the circle is:

=> x² + y² = r²

Apply the values,

=> x² + y² = 5²

=> x² + y² = 25

The point (3,y) is on the circle, in quadrant 4. This means that:

Replacing x by 3, we can find the value of y.

Quadrant 4 means that y < 0.

Then:

=> 3² + y² = 25

=> y² = 25 - 9

=> y² = 16

=> y = ±√16

=> y = - 4

The value of y is -4.

Suppose $2000 is deposited in a bank account with an annual compound interest rate of 3%. After two years, we will have accumulated 121.80 in interest on your initial 2000 deposit.

Compound interest is, to put it simply, interest that is earned on interest. Compound interest is interest that is earned on both the initial principal and interest that builds up over time in a savings account.

There may be a difference in the timing of when interest is paid out and compounded. For instance, interest on a savings account may be paid monthly but compounded daily. The account balance plus any interest that has accrued but has not yet been paid out are used by the bank to determine your daily interest earnings.

For the above question:

Account Balance = Principal x (1 + interest rate (decimal))^number of the years. With given information this is:  [tex]2000 (1.03)^2[/tex] = 2,121.80.  So we will earn 121.80 in interest after the 2 years on your original 2000 deposit.

By taking the quotient between the total debt and the number of people, we conclude that the debt per person is $2,622

To find the amount of debt per person, we need to find the quotient between the total amount of debt and the number of people.

Here the total debt is:

$6.39 billion = $6.39*10^9

And the total number of people is:

2.437 million = 2.437*10^6

Then the quotient is:

Q = ($6.39*10^9)/( 2.437*10^6) = $2.622*10^3

The debt per person is:

Answer:

LK = 7

Step-by-step explanation:

We are using segment addition

NM + ML + LK = NK

x-6  + 9 +  2x-19  = 23

Combine like terms

x+2x   -6+9-19 = 23

3x -16 = 23

Add 16 to each side

3x-16+16 = 23+16

3x = 39

Divide each side by 3

3x/3 = 39/3

x = 13

We want to find the value of LK

LK = 2x-19

     =2(13) -19

     = 26 -19

    = 7

Answer:

[tex]\sf \: LK = 7 \: units[/tex]

Step-by-step explanation:

It's clear that,

[tex] \sf \: NM + ML + LK = NK[/tex]

Given that,

NM ---> x - 6

ML ---> 9

LK ---> 2x - 19

NK ---> 23

First, let us find the value of x using these values.

[tex] \sf \: NM + ML + LK = NK \\ \sf x - 6 + 9 + 2x - 19 = 23 \\ \sf \: combine \: like \: terms. \\ \sf \: 3x - 16 = 23 \\ \sf3x = 23 + 16 \\ \sf3x = 39 \\ \sf \: divide \: both \: sides \: by \: 3. \\ \sf \: x = 13[/tex]

And now we have to find out the length of LK.

As we mentioned before,

LK = 2x - 19

So, to find the length of LK, we have to replace x with 13 and solve the equation.

Let us solve now.

[tex] \sf \: LK = 2x - 19 \\ \sf \: LK = 2 \times 13 - 19 \\ \sf \: LK = 26- 19 \\ \sf \: LK = 7 \: units[/tex]

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
