Guys please help i'm stup!d
Nataly [62]

Answer:

Option B: 0.4

Step-by-step explanation:

We have 20 dots.

Such that each column represents the repetitions for each proportion.

So:

0.1 -> 3 times

0.2 -> 1 time

0.3 -> 4 times

0.4 -> 6 times

0.5 -> 3 times

0.6 -> 3 times

Now we can compute the mean of these values, and that will be the best estimation we can make with the given data.

Remember that for a set of N values:

{x₁, x₂, ..., xₙ}

The mean is:

M = \frac{x_1 + x_2 + ... + x_n}{N}

In this case we have the set of 20 points described above, then the mean is:

M = \frac{3*0.1 + 1*0.2 + 4*0.3 + 6*0.4 + 3*0.5 + 3*0.6}{20} = 0.37

Rounding to the first place after the decimal point, we get:

M = 0.4

Then the correct option is option B.

Can anyone one solve 1 - 6 ?
VashaNatasha [74]

(1)

f(x) + g(x) = 3x + 2 + 2x + 5 = 5x + 7

f(x) - g(x) = 3x + 2 - 2x - 5 = x - 3

(2)

f(x) + g(x) = 4x - 1 + 3x - 4 = 7x - 5

f(x) - g(x) = 4x - 1 - 3x + 4 = x + 3

(3)

f(x) + g(x) = - 5x + 3 + 2x - 4 = - 3x - 1

f(x) - g(x) = - 5x + 3 - 2x + 4 = - 7x + 7

(4)

f(x) + g(x) = 3x - 4 - 2x + 3 = x - 1

f(x) - g(x) = 3x - 4 + 2x - 3 = 5x - 7

(5)

f(x) × g(x) = - 2(- x + 7 ) = 2x - 14

(6)

f(x) × g(x) = - 5(2x - 7) = - 10x + 35

Si un empresario paga diariamente 50 a cada trabajador le faltaria 110 pero si les pagara 45 le sobraria 60 cuantos trabajadores
N76 [4]

Answer:

34 trabajadores.

Step-by-step explanation:

Supongamos que el empresario tiene N trabajadores, y tiene la cantidad de dinero D para pagarles cada día.

Si el empresario decide pagarle 50 a cada trabajador le faltan 110.

Esto se puede reescribir como:

50*N = D + 110

(50 por número de empleados es igual que el dinero que tiene más lo que le falta para pagar)

También sabemos que si pagara 45 a cada empleado, le sobraría 60.

Esto se puede reescribir como:

45*N = D - 60

Entonces tenemos dos ecuaciones:

50*N = D + 110

45*N = D - 60

Para resolver esto, el primer paso es aislar una de las variables en una de las ecuaciones, en este caso aislaré D en la segunda ecuación.

45*N + 60 = D

Ahora podemos reemplazar esto en la primer ecuación y resolver para N

50*N = (45*N + 60) + 110

50*N = 45*N + 170

50*N - 45*N = 170

5*N = 170

N = 170/5 = 34

El empresario tiene 34 trabajadores.
