To get the probability , add all of the marbles together to get the 100%. There are 12 marbles total. Since there are four blue marbles, there is a 4/12 chance he will pick a blue marble. Simplify this to 2/6, and then 1/3 which in percentage is approximately 33.33%

Write a two column proof
Annette [7]

4y=2x-10 and y=6

use the second expression to calculate the left-hand side of the first equation:

4\cdot 6 = 2x -10\\24 = 2x -10

Add 10 to both sides if this equation to get

34 = 2x

and divide both sides by 2

17 = x

this proves that x = 17, give the two initial equations

Find the specified element in the inverse of the given matrix
JulijaS [17]
What is the given matrix?
you didn't show a matrix.
the components of the matrix are the elements.
and the elements of the inverse matrix are the elements of the inverse matrix
1) 
so if matrix A is  1   4  1   
                          2   5  2
                          3   6  3
2)
14114
25225
36336

3)
15 24 12
15 12 24
4)
[A]=(15+24+12=51)-(15+12+24=51)
[A]=0
5)
    52    23   25
    63    23   36

    41    11   14 
    63    33   36

    41    12    14
    52    12    25
6)

    15-12   6-6   12-15

     12-6    3-3    6-12

      8-5     2-2     5-8


7) 
     3    0   -3

     6    0   -6

     3    0   -3
 8) 
     (+)3    (-)0   (+)-3

     (-)6    (+)0   (-)-6

     (+)3    (-)0   (+)-3
=

    3  0  -3
   -6  0   6
    3  0  -3

9)
        3 -6  3
N=   0  0  0
       -3  6 -3
10) the inverse of [A]= 1/|A|*[N]
which is in this case ⁻A= 0
because |A|=0
