You can multiply matrices if and only the number of the columns in the first matrix equals the number of rows in the second matrix. Otherwise the product of the two matrices is undefined

You can only multiply them if the number of the first column (up and down) is the same as the 2nd row (across)

What is X equal to? PS it’s not 180

AVprozaik [17]

Answer:

x = 47

Step-by-step explanation:

86° and 2x° are supplementary angles, which means that added together they should equal 180° (which is a line). Aka

86 + 2x = 180 (Let's solve for x) (subtract both sides by 86 to get x on one side)

2x = 94 (divide both sides by 2 to get x by itself)

x = 47

Suppose you draw a card from a well-shuffled deck of 52 cards. Find each of the following odds.

garik1379 [7]

1) number of cards that aren't : number of cards that are 3
we have 48 cards that arent 3 and 4 cards that are. that means that odds are:
12:1 of not drawing 3

2) fallow same logic. its just opposite.
1:12

3) same logic. but there are only 2 black 7 cards which means that odds are:
50:2 or
25:1

4) opposite of previous.
1:25
