<span>1/3(21-3a)=6-a
I simplified the equation to the form, which is simple to understand
<span>1/3(21-3a)=6-a
Simplifying:
<span> + 0.333333333333*(21-3a)=6-a
Reorder the terms in parentheses
<span>+(+7-1a)=6-a
Remove unnecessary parentheses
<span>+7-1a=+6-a
We move all terms containing a to the left and all other terms to the right.
<span>-1a+1a=+6-7
We simplify left and right side of the equation.
<span>a=-1
<span>0=-1
The left and right sides are not equal, therefore there is no solution. This equation is invalid
Hope this helped

Answer:
-4/3x + -28/3
Step-by-step explanation:
First you rearrange 4y-3x=1
y= 3/4x +1/4
then you reciprocate and change the sign the slope since you are trying to find a line perpendicular to it.
Slope(m) =-4/3
then you use the formula <em>y-y1= m(x-x1)</em>
y-0= -4/3 (x--7)
y= -4/3 +-28/3
Answer:
Step-by-step explanation:
Given that the number of drivers who travel between a particular origin and destination during a designated time period has a Poisson distribution with parameter μ = 20 (suggested in the article "Dynamic Ride Sharing: Theory and Practice"†).
a) 
b) 
c) 
d) 2 std dev = 2(20) =40
Hence 2 std deviation means
20-40, 20+40
i.e. (0,60)
25% should be the answer, let me kno if its correct
