How do you estimate the mean? please help

Answer:

v = 21

Step-by-step explanation:

the sum of the interior angles of a triangle is 180 degrees

add all 3 angle measures and set equal to 180:  

4v + 2v + 54 = 180

6v = 126

v = 21

Answer:

x = 2/5 or 0.4

Step-by-step explanation:

3x - 6 = 4(2 - 3x) - 8x

distribute

3x - 6 = 4*2 - 4*3x - 8

3x - 6 = 8 - 12x - 8

combine like terms

3x - 6 = -12x

add 12x to both sides of the equation

3x - 6 + 12x = -12x + 12x

3x - 6 + 12x = 0

15x - 6 = 0

add 6 to both sides of the equation

15x - 6 + 6 = 0 + 6

15x = 6

divide both sides of the equation by 15

15x/15 = 6/15

x = 6/15

x = 2/5

x = 0.4

Answer:

1)6x

Answer: The length of the other diagonal is 8 cm.

Step-by-step explanation:

Area of rhombus = [tex]\frac{pq}{2}[/tex]

[tex]\frac{4q}{2} =16\\[/tex]

[tex]4q = 32\\q = 8\\[/tex]

The length of the other diagonal is 8 cm.

The probability of getting numbers whose sum is a multiple of three is,

⇒ 1 / 3

Since, The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Here, We have;

There are 48 possible outcomes in this situation, and of those outcomes, the ones whose sums are a multiple of three are;

12, 21, 15, 51, 24, 42, 33, 18, 27, 36, 63, 45, 54, 48, 57, and 66.

So, that is 16 out of 48 possibilities,

⇒ 16/48,

⇒ 1/3.

Thus, The probability of getting numbers whose sum is a multiple of three is,

⇒ 1 / 3

Answer:

A. 3.7, because |3.7| = 3.7

Step-by-step explanation:

What the question is referring her by magnitude is units away from 0. 3.7 is 3.7 units away from 0, which is the same thing as the absolute value of 3.7. And since absolute value is always positive, C is already out. D is also out as the value doesn't change. B's reason contradicts the answer, so it is also wrong. This leaves A (3.7, because |3.7| = 3.7) as our answer.

2- 90 + 8 -1 = -81

Step-by-step explanation:

Answer:

50

Step-by-step explanation:

Since 140° is on the outside, the angle next to it would be 40°.

Also a triangle = 180°

40° + 90° = 130°

180° - 130° = 50°

Thus meaning x = 50°

Answer:

x = 50°

Step-by-step explanation:

- the angle at the top is shown as a right angle so it is 90°

-the 140° angle and the angle next to it are 180° together so let's name the other angle z

z+140=180

z=180-140=40°

- a triangle's angles in total have 180°

x+y+z= 180°

x+90°+40°=180°

x+130 =180

x= 180-130 = 50°

$ 11,137

Explicación paso a paso:

Como no se nos dice qué encontrar, también podemos encontrar el beneficio obtenido por la venta de 351 unidades de radio.

Dado

Función de costo C (x) = 43x + 1850

Función de ingresos R (x) = 80x

Obtener la función de ganancias

P (x) = R (x) - C (x)

P (x) = 80x - (43x + 1850)

P (x) = 80x - 43x - 1850

P (x) = 37x - 1850

Si se fabrican 351 radios, la ganancia obtenida se calculará como se muestra a continuación:

P (351) = 37 (351) - 1850

P (351) = 12,987-1850

P (351) = 11,137

Por lo tanto, la ganancia obtenida de las ventas de 351 radios es de $ 11,137
