The lowest common denominator of LCD is least common multiple of denominators of the fractions.

given fractions:

1/6, 13/27, 4/5, 3/10, 2/5

taking the Prime factorization of denominator of the fractions

6 = 2x3x1

27 = 3x3x3x1

5 = 5x1

10 = 2x5x1

5 = 5x1

Therefore, lcm is 2x3x3x3x5 = 270

De acuerdo a la información, se puede inferir que la probabilidad de cada empleado para ganarse un televisor es de 0.3. Por otra parte, la cantidad de televisores que maquilla cada empleado es 2.

Para calcular la probabilidad de cada empleado de ganarse un televisor utilizamos la siguiente formula:

De acuerdo a la formula, solo tenemos que remplazar los valores, el número de casos favorables es 3 debido a que hay 3 televisores en total el sorteo, y el número de casos posibles, es 10 debido a que 10 empleados están participando en la rifa, como se muestra a continuación:

Para calcular cuántos televisores maquilla cada empleado debemos tener en cuenta que la empresa produce 20 televisores y que tiene 10 empleados. Entonces tenemos que dividir el numero de televisores en el número de empleados como se muestra a continuación:

The height of the building to the nearest tenth of a meter is; 13 m

The slant line from the top of Trevor's head to the base of the building is gotten from Pythagoras theorem;

15/x = sin 36°

x = 15/sin 36

x = 25.52 m

Angle between that slant line and base of building is;

90 - tan⁻¹(1.5/14) = θ

θ = 83.88°

Remaining angle of the bigger triangle is;

180 - (36 + 83.88) = 60.12°

Thus, if the height of the building is h, then;

h/sin 36 = 25.52/sin 60.12

h = 13 m

The probabilities that correctly complete this probability distribution for 50 packages of nuts will be 0.24, 0.2, 0.12, 0.28, and 0.16.

From the information given, we have to find the probability for each fruit. This will be:

Almond = 12/50 = 0.24

Cashew = 10/50 = 0.2

Mixed = 6/50 = 0.12

Peanut = 14/50 = 0.28

Pecan = 8/50 = 0.16

Therefore, the probabilities that correctly complete this probability distribution for 50 packages of nuts will be 0.24, 0.2, 0.12, 0.28, and 0.16.

The third term, fourth term and tenth term are -1, -3, -15 respectively.

A sequence is a pattern of numbers in which successive terms differ by an constant term called the common difference or ratio.

Analysis:

For a sequence defined by the rule A(n) = 3 + (n-1)(-2)

Third term, n = 3

A(3) = 3 + (3-1)(-2) = -1

Fourth term, n = 4

A(4) = 3 + (4-1)(-2) = -3

Tenth term, n = 10

A(10) = 3 + (10-1)(-2) = -15

In conclusion, the third, fourth, tenth terms are -1, -3 and -15 respectively.

Answer:

Hey there!

Arithmetic sequences are made up of terms that are added or subtracted, and geometric sequences are made up of terms that are multiplied or divided.

Given this info, we can see that we go from 10 to -5. Because we know that this is geometric, we see that we must divide by -2 in our sequence.

We can see that this is true because -5/-2=5/2.

Now, we could simply continue dividing by negative two to get our answer, which is -5/16.

You could easily do that with a calculator, but if you had to find a term that was farther from the first term, that would take forever to do with a calculator, so there is an equation that you can use and plug in your numbers to find the answer quickly.

Given the radius of the discus used in the track field competition, the circumference of the discus is 69.08cm.

Note that; a circumference is the perimeter of a circle or ellipse.

It is expressed as C = 2πr

Where r is the radius and π is the constant pi ( π = 3.14 )

Given that;

C = 2πr

C = 2 × 3.14 × 11cm

C = 69.08cm

Therefore, given the radius of the discus used in the track field competition, the circumference of the discus is 69.08cm.

If 5x + 15 ≥ 0, then |5x + 15| = 5x + 15. The equation reduces to

5x + 15 = 10x

15 = 5x

x = 3

If instead 5x + 15 < 0, then |5x + 15| = -(5x + 15), and the equation becomes

-5x - 15 = 10x

-15 = 15x

x = -1

If x = 3, then |5x + 15| = 30 and 10x = 30, so x = 3 is a valid solution.

If x = -1, then |5x + 15| = 10 while 10x = -10, so x = -1 is the extraneous solution.

Using function concepts, it is found that the statement that correctly describes the function is:

C. This is the graph of a one-to-one function.

A graph represents a function if it is one-to-one, that is, each value of x is mapped to one value of y.
