Answer: None the zeroes have a multiplicity of 2.
Step-by-step explanation: i took the test
This is quite difficult to try to explain so I'm going to set up some matrices to demonstrate as best as I can. If matrix A has 3 rows and 2 columns, it would be respresented as
. This matrix can only be multiplied by another matrix that has the same number off rows as the number of columns in A. For example, if matrix B has 2 rows and 3 columns, it would be represented as
. If we set them next to each other, it might be easier to see the rule:
. The 2's match, and the other numbers represent how your solution matrix will look. Your solution matrix will be a 3x3. Here is matrix A:
and here's B:
. We can multiply these according to the rules. The multiplication works like this:
. first row of A times first column of B: (1*1)+(2*4) = 9. that goes into row 1 column 1 of your solution matrix. Go va to row 1 in A but column 2 in B: (1*2)+(2*5) = 12. That goes into row 1 column 2 of your solution matrix. Next row 1 of A and column 3 of B: (1*3)+(2*6) = 15. That goes into the first row column 3 of the solutiong matrix. Now move to row 2 of A column 1 of B: (3*1)+(4*4) = 19. That goes into row 2 column 1 in your solution matrix. Next row 2 A, column 2 B: (3*2)+(4*5) = 26. That goes into row 2 column 2 solution matrix. Continue as I showed you. You should be fine.
Answer:
Green: 50%
Purple: 25%
Black: 25%
Step-by-step explanation:
Well, the circle has 4 equal sections.
2 are green
1 is purple
1 is black
To find the probability of the spinner landing on each section we make a fraction.
Green)
2/4 simplified,
1/2, as a percent is 50%
Purple)
1/4,
1 divided by 4 = .25
To make that into a percent we move the decimal 2 places to the right -> 25%
Black)
1/4
1 divided by 4 = .25 as a percent 25%

Answer:
In mathematics, a real number is a value of a continuous quantity that can represent a distance along a line (or alternatively, a quantity that can be represented as an infinite decimal expansion).
