Among the four survey results, there seems to be one that has a different trend. For Surveys 1, 3 and 4, the number of families that owns pets increases with the number of pets that they own. Survey 3 has a different result. This could be caused by a bias. Based on the three surveys, there around
25/50 = 50%
27/50 = 54%
27/50= 54%

A is a 4x4 matrix and A^2 + 4A - 5I = 0. If det(A+2I)&gt;0, enter det(A+2I)
maw [93]
\mathbf A^2+4\mathbf A-5\mathbf I=0
\implies\mathbf A^2+4\mathbf A+4\mathbf I=(\mathbf A+2\mathbf I)^2=9\mathbf I
\implies\det\bigg((\mathbf A+2\mathbf I)^2\bigg)=\det(9\mathbf I)
\implies\det(\mathbf A+2\mathbf I)^2=9^4\det\mathbf I
\implies\det(\mathbf A+2\mathbf I)=\pm\sqrt{9^4}
\implies\det(\mathbf A+2\mathbf I)=9^2=81

where we take the positive root because we're told that the determinant is positive.

kkurt [141]

\quad \huge \quad \quad \boxed{ \tt \:Answer }

\qquad \tt \rightarrow \: 36 + 23 i

____________________________________

\large \tt Solution  \: :

\qquad \tt \rightarrow \: (3 + 8i)(4 - 3i)

\qquad \tt \rightarrow \: (3 \sdot 4)+ (3 \sdot - 3i) + (8i \sdot4) + (8i \sdot - 3i)

\qquad \tt \rightarrow \: 12 - 9i + 32i  - (24  {i}^{2} )

\qquad \tt \rightarrow \: 12 + 23i -( 24 \sdot - 1)

\qquad \tt \rightarrow \: 12 + 23i + 24

\qquad \tt \rightarrow \: 36 + 23i
