Let point A(0,-2)
and B(2,-5)
slop of line equals to
(2-0)/(-5-(-2))=2/-3=-2/3
y=mx+c
y=-2/3x+c
Verify piont A
-2=-2/3×0+c
c=-2
Final equation of line is
y=-2/3x-2
2x+3y+6=0
Now choose any random point it positive
2x+3y+6>0
Oh OK
Perimeter = 2l + 2w = 44
l + w = 22
if l = 12 then w = 120/12 = 10
if l <_ 12 then w >_ 10
Its A
Answer:
The purpose of statistical inference is to provide information about the population based upon information contained in the sample.
Step-by-step explanation:
population based upon information contained in the sample
Step-by-step explanation:
Statistical inference is the process of using data analytics to deduce proprierties of an underlying probability distribution.
For example, if I want to know the percentage of Buffalo Bills fans that are from Canada. There is no way I can ask this question to every Bills fan(every Bills fan is the population). What I can do, for example, is go to a game and ask some of the fans there, that is, of a sample.
Answer:
factors are any group of number or expressions which, when multiplied, produce another number or expression.
Basic example: 4 can be broken into 2 factors---2 and 2. 2 times 2 = 4
Example using an unknown:
2X + 6 = 2 * (X + 3)
In the given problem, there is no whole-number common factor. A normal convention would be to factor based on the unknown term----thus 8X is factored into 8 and X.
So: 8X + 7 = 8 ( X + 7/8 )
The following would also be correct:
8X + 7 = 4 ( 2X + 7/4 )
Step-by-step explanation:
