An estimated regression model has the form: Sales (in dollars) = 5 + .6 * Advertising Spending (in dollars) + .9 * Price (in dollars). Which of the following interpretations is correct about the effect of price: Question 1 options: Keeping advertising spending constant, one dollar increase in price is associated with a .9 dollar increase in sales. Keeping advertising spending constant, a .9 dollar increase in price is associated with one dollar increase in sales. Keeping advertising spending constant, one dollar increase in price is associated with a .9% dollar increase in sales. Keeping advertising spending constant, a .9 dollar increase in price is associated with one dollar increase in sales.

The amount of money a family spend on groceries is directly correlated with the number of people in the family. The more people in the family, the more money that is spent on groceries each month. In this example, the number of people in the family would be the independent variable (x) while the amount of money spent on groceries each month would be the dependent variable (y). A scatterplot would show a strong positive linear correlation. This will not be a perfectly positive correlation. Some reasons why the correlation will not be perfectly positive are because some families will prefer to buy more or less expensive brands of food, families with smaller children will likely spend less than families with older kids, some families will choose to dine out at restaurants more, some families choose only high quality or organic products, etc. # spent on groceries monthly # of people in the family [2 pts] Give an example of two variables that have either a positive or negative correlation. You must use different v

(a) Using elementary Newtonian mechanics, find the period of a mass 𝑚1 in a circular orbit of radius 𝑟 around a fixed mass 𝑚2 (the masses interact via gravity). (b) Using the separation into CM and relative motions, find the corresponding period for the case that 𝑚2 is not fixed and the masses circle each other a constant distance 𝑟 apart. Discuss the limit of this result for the case that (i) 𝑚2 → ∞ and (ii) 𝑚2 → 𝑚1. (c) What would be the orbital period of two black holes with masses of 2.00 × 10^8 𝑀𝑆𝑢𝑛 and 1.25 × 10^8 𝑀𝑆𝑢𝑛 orbiting at a distance of 100 𝐴𝑈? How fast would each black hole be moving? Assume the motion is non-relativistic and state your answers as percentages of the speed of light. Such collisions would generate huge amounts of gravitational radiation but at wavelengths far longer than what LIGO can detect. This is the goal for the Laser Interferometer Space Antenna (LISA), set to launch in 2037.

[CLO-4] Consider an adiabatic steady throttling process of R-134a. R-134a enters the valve at 700 kPa and 25.5 °C, as compressed liquid. The refrigerant expands in this process to a pressure of 100 kPa. Based on above data, it is expected that the phase at the valve exit is: Selected Answer: Answers: Saturated liquid-vapor mixture Superheated vapor Saturated liquid-vapor mixture Saturated liquid Saturated vapor
