For this case, we must subtract the given matrices, for this we subtract term to term.
So, we have:
Equal signs are added and the same sign equals:
![\left[\begin{array}{ccc}-2-2\\-2-1\\1-1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-2-2%5C%5C-2-1%5C%5C1-1%5Cend%7Barray%7D%5Cright%5D)
=
![\left[\begin{array}{ccc}-4\\-3\\0\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-4%5C%5C-3%5C%5C0%5Cend%7Barray%7D%5Cright%5D)

Answer: option A
Step-by-step explanation: We can only make a conclusion regarding this question by picking a level of significance.
Hence I will assume a 5% level of significance, that's α = 0.05.
If p > α, it simply means that we have a high chance of committing a type 1 error (because α is the probability of committing a type 1 error), hence we reject the null hypothesis meaning it is wrong.
If p < α, it means that we have a very low chance of committing a type 1 error hence we accept the null hypothesis because it is right.
Note even if we decide to try any reasonable value of α, we will come to the same conclusion made above.
Answer: Close. Your observation is correct. When you see that the difference between two numbers in the sequence is a perfect square, you are looking at a pyramidal sequence
1² = <u>1 </u> top of pyramid
1 + 2² = <u>5</u> total in top 2 layers
1 + 2² + 3² = <u>14</u> total in top 3 layers
1 + 2² + 3² + 4² = <u>30</u> total in the top 4 layers.
1 + 2² + 3² + 4² + 5² = <u>55</u> total in the top 5 layers.
Layer 6 is 6² more, 91
Layer 7 is 7² more so, 140
I think you got it.
Step-by-step explanation: The numbers are like when you keep adding the layers in a pyramid, and the next number is the total of the previous layers plus the square of the next layer number.
I think it’s either a or c I’m not sure but I’m going for c please lmk if I’m wrong
