The problem statement gives the correct answers for parts (a) and (b). The total number of roots of the characteristic polynomial is the dimension of the matrix: 6. The eigenvalues are the zeros of the characteristic polynomial, 3 (multiplicity 2), 6 (multiplicity 3), and -1.
(c) The matrix is not invertible when one or more eigenvalues is zero. None of yours are zero, so the matrix is invertible.
The data shown in the line plot is skewed right
Step-by-step explanation:
looking at the diagram, AC is the hypotenuse, AD is the adjacent and CD is the opposite (based on the position of the angle).
Since you are looking for CD, you would use Sine (SOHCAHTOA). Sine would be opposite over hypotenuse and following the same procedure, you will the cross multiply to get your answer
Answer:
<u>73</u>
Step-by-step explanation:
2+2+3+65+1
=4+3+65+1
=7+65+1
=72+1
=73
43 because the x represents the number of coupons and if 0 coupons were sold the 3.4 *0 is 0 and 0 + 43 is 43
