Answer:
1/7
Step-by-step explanation:
there are 7 number possibilities 0,1,2,3,4,5,6.
so if they each have an equal probability the answer is 1/7
X=7%
y=12%
x+y=20000
0.07x+0.12y=20000*0.19=3800
The x value in the second equation (y+2) is substituted for the x in the first equation in...
Answer A.
A + b = d+c
<span>a - b = e - c </span>
The b and c cancel out.
<span>2a = d+e </span>
<span>a = (d+e)/2 </span>
