Masses M1 … M10 are ‘lumped’ at ‘nodes’ 1 to 10Stiffness K1 … K10 prevent relative lateral movement […]
Solving the minimisation problemUse calculus: take the first order derivative w.r.t. eachˆβkand set them tozero (i.e.first order conditions)n∑i=1(yi−ˆβ0−ˆβ1x1i−ˆβ2x2i)=0n∑i=1x1i(yi−ˆβ0−ˆβ1x1i−ˆβ2x2i)=0n∑i=1x2i(yi−ˆβ0−ˆβ1x1i−ˆβ2x2i)=0Solving these equations simultaneously yieldsˆβ0,ˆβ1,ˆβ2One can solve these equations only if the regressors are not perfectly linearlyrelatedAlgebraic properties: FOC]1→∑ni=1ˆui= 0 and FOC]2→∑ni=1ˆuix1i= 0and FOC]3→∑ni=1ˆuix2i=
SHOW ALL CALCULATIONS AND EXPLAIN YOUR METHOD Using the question 1 sheet in the ‘F2 Random Number Generator’ file, insert the values for x and y in the table below and include a copy with your answers to the following questions. For the bivariate data generated, find the equation of the least squares regression line […]
MNGT 213: Assessment 3 Questions It is believed that educational attainment is higher in countries with higher expenditure on education as a percentage of GDP. Assuming that there is a linear relationship between expenditure on education as a percentage of GDP and percentage of labour force (over 25years old) with at least post-secondary education for […]

What techniques, methods and methodologies are used?
Define the binary operator @ by: aa@b=2bb=2b Simplify each of the following. Do the order of operations (do what is in parentheses first). (4(4@6)6)@3=3= (2(2@7)7)@5=5= 11. Define the binary operator ⊕⊕ by: a⊕b=4aba⊕b=4ab Simplify each of the following. Do the order of operations (do what is in parentheses first). (2⊕4)⊕3=(2⊕4)⊕3= (5⊕7)⊕6=(5⊕7)⊕6= 12. Define the binary operator # […]
