Answer:
Survey data should not be treated as interval data because the measure distance between categories may not be perceived as the same.
Step-by-step explanation:
Maybe you can be right with the ranking, for example:
White = 1
Grey = 2
Black = 3
But most sure the grey will be closer to black than it is to white, or vice versa.
I can infer that the people in the picture are running from someone or somebody called Anthropologists they are also taking all there belongings so they probably don’t expect to comeback

Step-by-step explanation:
The given matrices are;
![B = \left[\begin{array}{ccc}5&1&7\\3&15&-2\\-1&-9&25\end{array}\right]](https://tex.z-dn.net/?f=B%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D5%261%267%5C%5C3%2615%26-2%5C%5C-1%26-9%2625%5Cend%7Barray%7D%5Cright%5D)
The cross product of the matrices is found as follows;
![A \cdot B = \left[\begin{array}{ccc}1&7&-1\\5&-2&-9\\-3&8&3\end{array}\right] \times \left[\begin{array}{ccc}5&1&7\\3&15&-2\\-1&-9&25\end{array}\right]](https://tex.z-dn.net/?f=A%20%5Ccdot%20B%20%3D%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%267%26-1%5C%5C5%26-2%26-9%5C%5C-3%268%263%5Cend%7Barray%7D%5Cright%5D%20%5Ctimes%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D5%261%267%5C%5C3%2615%26-2%5C%5C-1%26-9%2625%5Cend%7Barray%7D%5Cright%5D)
C₁₁ = 1×5 + 7×3 + (-1) × (-1) = 27
C₁₂ = 1×1 + 7×15 + (-1)×(-9) = 115
C₁₃ = 1×7 + 7×(-2) + (-1)×25 = -32
C₂₁ = 5×5 + (-2)×3 + (-9) × (-1) = 28
C₂₂ = 5×1 + (-2)×15 + (-9)×(-9) = 56
C₂₃ = 5×7 + (-2)×(-2) + (-9)×25 = -186
C₃₁ = (-3)×5 + 8×3 + 3 × (-1) = 6
C₃₂ = (-3)×1 + 8×15 + 3×(-9) = 90
C₃₃ = (-3)×7 + 8×(-2) + 3×25 = 38
Therefore, we get;
![A \cdot B = \left[\begin{array}{ccc}1&7&-1\\5&-2&-9\\-3&8&3\end{array}\right] \times \left[\begin{array}{ccc}5&1&7\\3&15&-2\\-1&-9&25\end{array}\right] = \left[\begin{array}{ccc}27&115&-32\\28&56&-186\\6&90&38\end{array}\right]](https://tex.z-dn.net/?f=A%20%5Ccdot%20B%20%3D%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%267%26-1%5C%5C5%26-2%26-9%5C%5C-3%268%263%5Cend%7Barray%7D%5Cright%5D%20%5Ctimes%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D5%261%267%5C%5C3%2615%26-2%5C%5C-1%26-9%2625%5Cend%7Barray%7D%5Cright%5D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D27%26115%26-32%5C%5C28%2656%26-186%5C%5C6%2690%2638%5Cend%7Barray%7D%5Cright%5D)
