Answer:
Mean is the same as average so you simply take 4+5+9+2+104+5+9+2+10+6+7+9+8=180 but for it to be average you also have to divide by the number of values used which in this case is 13 so you take 180/13=13.85 if you round to the second decimal place
Step-by-step explanation:
please give brainliest if this helped
Use the Pythagorean theorem:
Equation of a line passing through point (x1, y1) with slope m is given by y - y1 = m(x - x1)
For parallel lines, the slope of the required line is equal to the slope of the given line.
x = -3 is a vertical line, therefore, the required line will also be a vertical line since they are parallel.
Since the required line passes through point (4, 2), the equation of the required line is x = 4.
I have to assume that you want the answer in Spanish *but without using accents).
Usa las siguientes variables:
d = numero de habitaciones dobles
i = numero de habitaciones individuales
Por la primera premisa:
d + i = 180
Por la segunda premisa, los costos son tales que:
78d + 72i = 7839
Para resolver ese sistema podemos despejar una de las variables de la primera ecucacion y sustituir en la segunda:
i = 180 - d
78d + 72 (180 - d) = 7839
78d + 12960 - 72d = 7839
De aqui ya veo que va a dar un numero negativo para el numero de habitaciones dobles, asi que supongo que algun dato en el enunciado esta equivocado.
6d = 7839 - 12960 = -5121
=> d = -5121 / 6 = - 853.5
Al corregir los datos podras seguir el procedimiento que te he explicado para encontrar la solucion.
