What is the slope of the line? PLEASE PLEASE HELP FAST!

Answers

Answer:

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (1, 2) ← 2 points on the line

m = [tex]\frac{2-0}{1-0}[/tex] = [tex]\frac{2}{1}[/tex] = 2

Cual transformación produce acercamientos de las gráficas al eje de Y en el plano de coordenadas

Answers

Answer:

El eje horizontal en el plano de coordenadas se llama eje-x. El eje vertical se llama eje-y. El punto en el que los dos ejes se intersectan se llama origen.

Step-by-step explanation:

El plano de coordenadas se desarrolló hace cientos de años y fue refinado por el matemático Francés René Descartes. En su honor, se le conoce también como sistema de coordenadas Cartesianas. El plano de coordenadas puede usarse para graficar puntos y rectas. Este sistema nos permite describir relaciones algebraicas de una manera visual, y también nos ayuda a interpretar conceptos algebraicos.

In a completely randomized design involving three treatments, the following information is provided:Treatment 1Treatment 2Treatment 3Sample Size5105Sample Mean489The overall mean for all the treatments is _______.

Answers

Answer:

7.25

Step-by-step explanation:

Given :

___________ Sample size __ sample mean

Treatment 1 ____ 5 _______ 4

Treatment 2 ____ 10 ______ 8

Treatment 3 ____ 5 _______ 9

Sample size = (5 + 10 + 5). = 20

Overall mean = ((5*4). + (10*8) + (5*9)) / 20

Overall mean = (20 + 80 + 45) / 20

= 145 / 20

= 7.25

so what is really the answer?

The mean age of 5 women in an office is 23 years old. The mean age of 3 men in an office is 24 years old. What is the mean age (nearest year) of all the people in the office?

Answers

Answer:

Step-by-step explanation:

Women total age = 5 x 23 = 115

Men total age = 3 x 24 = 72

The mean age of all the people

= (115+72)÷(8)

= 23.375

= 23 (nearest year)

The mean age (nearest year) of all the people in the office is 23

How to determine the mean age?

The given parameters are:

5 women = 23 years

3 men = 24 years

Mean is calculated using:

[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]

So, we have:

[tex]\bar x = \frac{23 * 5 + 24 * 3}{5 + 3}[/tex]

Evaluate the quotient

[tex]\bar x = 23[/tex]

Hence, the mean age (nearest year) of all the people in the office is 23

Si a una persona le deben 7/9 de $450000 y sólo le cancelan 3/5 de esa deuda. ¿Cuánto dinero le quedan debiendo?

Answers

Answer:

$140,000

Step-by-step explanation:

Paso 1

Si a una persona le deben 7/9 de $ 450,000

La cantidad que se le debe a la persona se calcula como:

7/9 × $ 450,000

= $ 350,000

Paso 2

Solo se cancela 3/5 de esa deuda.

El monto de la deuda que se cancela se calcula como:

3/5 × $ 350,000

= $ 210,000

Paso 3

Por lo tanto, la cantidad de dinero que debe se calcula como:

$ 350,000 - $ 210,000

= $ 140,000

Determine the equation of the line parallel to the line y=34x+2
y=3/4x+2 that passes through the point (4, -3).

Answers

Answer:

y = 34x - 139 (y = 34x + 2)

y = [tex]\frac{3}{4}[/tex]x - 6 (y = 3/4x +2)

Step-by-step explanation:

(I'm not sure if the two equations were the same or not, but I provided the answers just in case.) Parallel lines are two lines that have the same plane and slope but never intersect. To find the equation, use the formula y - [tex]y_{1}[/tex] = m (x - [tex]x_{1}[/tex])
