NO.

Step-by-step explanation:

Se vende2 usb en 60 soles cada uno. En una se ganó el 20% y en la otra se perdió el 20% ¿Se ganó o se perdió en total y cuánto?
aniked [119]
Voy a responder en el mismo idioma en que está la pregunta.

1) Venta con ganancia

Precio de venta 60 soles.

Ganancia = 20% del costo => costo + 0,20 * costo =  precio

=> costo (1 + 0,20) = precio = 60 soles

=> costo (1,20) = 60 soles => costo = 60 soles / 1,20 = 50 soles

2) Venta con pérdida del 20%

Pérdida = 20% del costo

=> costo - precio = 20% * costo => costo - 0,20*costo = precio

=> costo ( 1 - 0,20) = 60 soles => costo * 0,80 = 60 soles

=> costo = 60 soles / 0,80 = 75 soles

3) Costo total = 50 soles + 75 soles = 125 soles

4) Ganancia total = valor total de venta - costo total

Ganancia total = 2 * 60 soles + 125 soles = 120 soles - 125 soles = - 5 soles.

El signo negativo significa que al final se perdió 5 soles en la operación.

(a) Predict the median income of a region in which 30% of adults 25 years and older have at least a bachelor's degree.
Step2247 [10]

Answer:

(a). $35746. (b). Higher.

Step-by-step explanation:

(a). Given that the least-squares regression equation is y = 7163x + 14242. Also, in the question above we are given that y is the median income and x is the percentage of 25 years and older with at least a bachelor's degree in the region, that is to say that the value of x = 30.

Therefore, y = 7163x + 14242.

y = (7163 × 30) + 14242.

y = $35746.

(b). The condition for our x is; 28.7 percent of adults 25 years and older have at least a bachelor's degree.

Then, y = (7163 × 28.7) + 14242.

y = $34814.

Hence, we have the median income in this region = $38,163 HIGHER than $34814.

Answer:

M(x,y) = (4.8,4.4)

Step-by-step explanation:

Given

P(x_1,y_1) = (6,2)

Q(x_2,y_2) = (3,8)

m:n = PM:MQ = 3 : 2

Required

Determine the coordinates of M

To solve this, we make use of the following partition formula:

M(x,y) = (\frac{nx_2+mx_1}{n+m},\frac{ny_2+my_1}{n+m})

Substitute values for m, n, x's and y's

M(x,y) = (\frac{2*3+3*6}{2+3},\frac{2*8+3*2}{2+3})

M(x,y) = (\frac{24}{5},\frac{22}{5})

M(x,y) = (4.8,4.4)

<em>Option D is correct</em>

Please help question 4
Burka [1]

Answer:

40 miles

Step-by-step explanation:

let distance be d and time be t

Since d varies directly with t, then the equation relating them is

d = kt ← k is the constant of variation

To find k use the condition d = 75 when t = 3

k = \frac{d}{t} = \frac{75}{3} = 25

d = 25t ← equation of variation

when t = 1.6, then

d = 25 × 1.6 = 40 miles
