Students have asked these similar questions
If y = C1 + C2x +e2*(C3cosx + C4sinx), then the roots are
2. Use successive substitution to determine the roots of
2x² + 5xy = 25
x + xy = 30
Initiate the computation with guesses of x = 5 and y = 3.
An instructor of mathematics wishes to determine the relationship of grades
on a final examination to grades on two quizes given during the semester. Costing X1, X2
and X3 the grades of a student on the first quiz, second quiz and final examination respec-
tively, he made the following computations for a total of 120 students:
X, = 6-8
X, = 0-7
X3 = 74
S, = 1.0
S, = 0-80
S3 = 9-0
12 = 0-60
13 = 0-70
23 = 0-65
(1) Find the least square regression equation of X3 on X1 and X2.
(i) Estimate the final grades of two students who scored respectively 9 and 7, 4 and 8 on the
two quizes.
