Fecha: 1. (2 pt) Considere el flujo a través de una boquilla de motor de cohete. Suponga que el gas fluye a través de la boquilla es una expansión isentrópica de un gas calóricamente perfecto. En la cámara de combustión, el gas que resulta de la combustión del combustible y oxidante de cohetes está a una presión y temperatura de 10 atm y 3000 K, respectivamente; el peso molecular y el calor específico a presión constante del gas de combustión son 1/12 y 3250 J/kg - k, respectivamente. El gas se expande a la velocidad supersónica a través de la boquilla, con una temperatura de 1200 K en la boquilla. Calcule la presión en la salida. 2.

The fitted regression is Sales = 842 − 37.5 Price. (a-1) If Price = 1, what is the prediction for Sales? Note: Round your answer to 1 decimal place. (a-2) Choose the correct statement. multiple choice 1 An increase in price decreases sales. An increase in price increases sales. A decrease in price decreases sales. (b) If Price = 20, what is the prediction for Sales? (c) Choose the right option. multiple choice 2 The intercept is not meaningful as a zero price is unrealistic. The intercept is meaningful as sales will be maximum when price is zero.
