Answer:
** +2x
Step-by-step explanation:
All the other ones can be it any thing will have difference but how can you do it?
* -sign mutipulcation
2x+* can be different.
O c, OA is N X+2 and more is not a equation. * - can be times really any number.

Answer:
at t=0 the car has moved 0 feet, also you know it has a constant speed so you get the points:
P1:(0,0) therefore you know b, the y-intercept=0
P2:(8,840)
insert P2 into y=mx+b
840=8m+0
840/8=m
105=m
so the result is:
y=105x=105t=f(t)=d
Step-by-step explanation:
Answer:
The missing value is 2
Step-by-step explanation:
A direct variation satisfies the equation
.
Since the point (-18, 12) lies on this line, it must satisfy this equation.


Hence the equation of this line is 
Now we substitute x=-3 to find y.

Therefore the missing value is 2
Answer:
Range =94
σ² = 1,141.564
Standard Deviation = 33.78703
Step-by-step explanation:
First off to find the range, we find the highest value and subtract it to the lowest value. In this situation the values are:
Highest = 99
Lowest = 5
Range = 99 - 5
Range = 94
Now to find the variance of the sample data set, we first need to find for the mean of the data.
The mean of the data with be the sum of all the numbers in the data set divided by the number of samples.
5 + 14 + 26 + 50 + 60 +72 + 79 + 88 + 93 +94 + 99
That would equal 680
Then you divide the number of samples and that is 11 so the next equation is 680 divided by 11
So the then-
Mean = 61.81818
Now to find the variance we simply use the formula:
Now to find the variance we simply use the formula:
σ²=
σ²=
σ²=
σ²=
Now to find the standard deviation, we take the variance and get the square root of it.
Standard Deviation= 
Standard Deviation=
