Answer:
x=2.116
Step-by-step explanation:
-4x=x-6
4.58-4x-x=-6
-5x=-6-4.58
-5x=-10.58
x=2.116
Add all of them and them subtract by the value
Answer: 6456
Step-by-step explanation:
Ratio of yes to no= 7:5
Number if yes= 3766
Since total number of yes is 3766. To find the total number of votes, 3766 / (7/7+5)
= 3766/ (7/12)
= 3766 × 12/7
= 45192/7
= 6456
There were 6456 total votes
Well, let's first write these as points.
( 2 , 50 )
( 4 , 100 )
We can see that when "x" is reduced by 2, "y" is reduced by 50. This means that if we reduce "x" by 1, "y" will be reduced by 25. Thus, we can say that if "x" is 1, "y" will be 25.
( 1 , 25 )
What we know that 25 * 1 = 25, and that 2 * 25 = 50. We can see that multiplying "x" by 25 will give us our "y". We can now write this as an equation.
y = 25x
The standard deviation is the square root of the variance
so if the variance is 256, then the standard deviation is : sqrt 256 = 16 <==
