4. Use determinants to find all values of h such that the following linear system has...
5. Use the Factor Theorem to determine if - 3 is a root of h(x) = x3 – x2 + 27. Do not use synthetic division 6. Write a fourth-degree polynomial f(x) that has roots -2, -5,3 7. Without using your calculator, but by using the change of base equation, show me step by step how to find log, 200 in terms of logarithms with base 10
1. For each of the following regression models, write down the X matrix and 3 vector. Assume in both cases that there are four observations (a) Y BoB1X1 + B2X1X2 (b) log Y Bo B1XiB2X2+ 2. For each of the following regression models, write down the X matrix and vector. Assume in both cases that there are five observations. (a) YB1XB2X2+BXE (b) VYBoB, X,a +2 log10 X2+E regression model never reduces R2, why 3. If adding predictor variables to a...
