Find the inverse matrix or type

Mathematics
1 answer:
Nataly [62]1 year ago
5 0

Answer:

I don't know if you mean [3,-1] & [-5,3] or \left[\begin{array}{ccc}3&-1\\-5&3\end{array}\right]

The inverse for first ones are "none" because they're not square matrices.

However the inverse for \left[\begin{array}{ccc}3&-1\\-5&3\end{array}\right]  is  \left[\begin{array}{ccc}0.75&0.25\\1.25&0.75\end{array}\right].

Hope this helps.

Look at this set of 5 numbers: 21471 By how much would the mode decrease if the number 1 were added to the set?
Fofino [41]

Answer:

  • Zero

Step-by-step explanation:

The mode is the number of most repeated data in the set.

Given set 2, 1, 4, 7, 1 has mode 1 (repeated twice).

If we add 1 to the set the mode will remain 1 as it will repeat three times, so the mode won't change.

There is no change in mode, so the mode decrease is zero.
