0.48x13=6.24
Take the relative frequencies of each branch and multiply them together.
0.35 * 0.55 = 0.1925 or B
When you multiply by 100 you have to move the decimal place 2 places to the right.
When you multiply by 1,000 you have to move the decimal place 3 places to the right.
When you multiply by 102 and 103, there is no simple trick as with multiplying by 100 or 1,000.
Your final answer is B. <span>multiplying 31.04 by 1,000</span>
2 over 3 plus 5 equals 5 and 2 over 3
1.x+4y- - 67 =-1
x+4y+67=-1
x+4y=-1-67
X+4y=-68
2.2x-y+2z=-7
2x=-7+y-2z
x=-7/2+1/2y-z
x=-7/2+1/2y-z, y€R, z€R
Warning: I don’t have the € and R
3.-x+2y- -43=5
-x+2y+43=5
-x+2y=5-43
-x+2y=-38
x-2y=38
