Suppose you have been hired by a research firm trying to understand the market for Widgets (a hypothetical product).  Your analysis of the data indicates that the Demand curve for Widgets is estimated to be linear and given by equation Qd = 150 – 3P and the Supply curve for Widgets appears to be linear as well and is estimated as Qs = 2P – 20.   Graphically draw these two curves, labeling all relevant points (such as intercepts for each line) on the horizontal and vertical axes.

Given the two functions below: Y=10e-0.5q   and y=7ln5q Draw the two functions for the interval -1<q < 3. After the functions are drawn, identify which of the two functions represents the demand curve and name the intercept(s) formed.

Given the following: C(YT) = 200+ 0.75(Y-T) I(r) = 80-20r L(r,Y)=Y-90r G = 200 T = 75 M = 2500 P = 4 a) What is the exact expression for the IS curve (express Y in terms of r)? b) What is the exact expression for the LM curve (express Y in terms of r)?

Given the function f(x) = ln (x+1), x>0   In applying mathematical methods to economics/business problems, we use a broad menu of functions for the purpose of accurately specifying the properties of the economic variables in question. Find an example that you can use the above function to describe certain economic or business activity.

Which of the following is true? OA. Quantity rises and the effect on price is unknown B. Quantity is unknown and price rises OC. Quantity rises and price falls OD. Quantity and price rise q

Every year in September, the NFL (National Football League) announces official prices of their next Superbowl tickets. The official ticket prices for 2020 Superbowl ticket in the NFL official websites started from $4,500 per person and it was up to over $12,000 per person depending on the location of the seats from the field. However, about three fourth of all tickets were already distributed to the NFL teams. The other one fourth are distributed to the media, NFL partners and sponsors. As a result, a small fraction of a total of about 80,000 tickets were sold in the secondary market. Those tickets were available to buy and sell in the official NFL online sites and other ticket brokers. Given the limited supply of tickets available to the NFL fans to purchase, the actual prices are dominated by the wide fluctuation of demand caused by many factors such as the venue of the game, the winning teams for the championship match, the packages of tickets offered by the brokers, and the weather…

Determine the total area under the standard normal curve in parts (a) through (c) below. (a) Find the area under the normal curve to the left of z = - 1 plus the area under the normal curve to the right of z = 1. The combined area is 03173 (Round to four decimal places as needed.) (b) Find the area under the normal curve to the left of z = – 1.55 plus the area under the normal curve to the right of z=2.55. The combined area is (Round to four decimal places as needed.)
