Answer:

$\boxed{\begin{bmatrix} 3 & - 1 \\ - 3 & 4\end{bmatrix} = 12 - 3 = \boxed{9} }\\ \\ \boxed{\begin{bmatrix} -12 & - 1 \\ 12 & 5\end{bmatrix} = - 60- ( - 12) = \boxed{ - 48}} \\ \\ \boxed{\begin{bmatrix} 0& - 1 \\ 17 & 4\end{bmatrix} = 0 -( - 17 )= \boxed{17}} \\ \\\boxed{ \begin{bmatrix} 8& - 1 \\ - 4 & - 1\end{bmatrix} = - 8 - 4 = \boxed{ - 12} }\\ \\ \boxed{\begin{bmatrix} 2 & - 1 \\ 2 & - 1\end{bmatrix} = - 2 - ( - 2) = \boxed{0}} \\ \\ \boxed{ \begin{bmatrix} 1 & 0\\ 0 &1\end{bmatrix} = 1 - 0 = \boxed{1}}$

Step-by-step explanation:

$the \: determinant \: of \: a \: matrix : A \to\\If \: A =\begin{bmatrix} x & y \\ a & b \end{bmatrix} \: then : \\ its \: determinant \: is \: givn \: by \to \\ |A| = (b \times x) - (a \times y) \\ \boxed{|A| = bx - ax}$

Examine the diagram, where BD is tangent to circle M at point D, and BA is secant to the same circle at points E and A.

Stella [2.4K]

Answer:

19 = x

Step-by-step explanation:

The square of the tangent segment = The product of (whole secant segment) (the outside part of the secant segment)

BD²= (BA)(BE)

8² = (4 + x - 7) (4) BA = BE + EB

8² = (x - 3)(4)

64 = 4x - 12

64 + 12 = 4x

76 = 4x

19 = x

Answer:

B. The interquartile range (IQR) for town A, 20, is greater than the

IQR for town B, 10.

Step-by-step explanation:

IQR = Q₃ - Q₁

For the town A:

Q₃ = 40 and Q₁ = 20

IQR of town A = 40 - 20 = 20

For the town B:

Q₃ = 30 and Q₁ = 20

IQR of town A = 30 - 20 = 10

Check the given options:

The most statement is appropriate comparison of the spreads is B
