The ocean around the san diego area experiences a mixed diurnal tide, which means that there are two high tides and two low tides per 24 hour cycle, but that they are different strengths. a group of ocean scientists want to make a model for the tide, so they measure the tide's position every 2 hours over a 24 hour period and get the following measurements: t 0 246 81012 14 16 18 2022 | 24 d 4.15.8 7.1 5.64.53.35.0 5.15.13.72.32.44.7 given that the tide is mixed diurnal, we know that it can be modeled by the equatioin d(t)-ab) +csin(2rt/12), sin (2mt/24 where t is measured in hours after midnight and d is the tide in meters. use the least squares method to solve for the constants a, b and c which will give a best fit model for the data

Asystem of linear equations with more equations than unknowns is sometimes called an overdetermined system. can such a system be consistent? illustrate your answer with a specific system of three equations in two unknowns. choose the correct answer below. a. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 6 b. no, overdetermined systems cannot be consistent because there are fewer free variables than equations. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 12 c. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 8 d. no, overdetermined systems cannot be consistent because there are no free variables. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 24
