Responder:
y = -6X + 36
Explicación paso a paso:
Dados los datos:
CANTIDADES __PRECIO
5 ___ 6
4 ___ 12
3 ___ 18
2 ___24
1 ___ 30
Usando una calculadora de modelo lineal:
La ecuación del modelo lineal obtenida con una calculadora de regresión es:
y = -6X + 36
Donde y = precio; - 6 = pendiente; Intercepción = 36
Se pudo observar que como reducción en la cantidad demandada puede ser como resultado de un aumento en el precio.
The train running at 45 km/hr would pass the jogger running at 9 km/hr after 36 s.
The relative speed of the train to the jogger must be determined to solve for the time that it would take to pass the jogger. The jogger and the train go in the same direction. Therefore, their relative speed would be based on the difference of their speed.
Relative speed = 45 km/hr - 9 km/hr
Relative speed = 36 km/hr
Converting relative speed of km/hr to m/s:
(36 km/hr)(1000 m/km)(1 hr/3600s)= 10 m/s
The formula that will be used is distance/speed.
time= total distance/ relative speed
time = (240 m + 120 m) / 10 m/s
time = 36 s
