Answer:
3. Correlation coefficients can be represented by the variable r
Step-by-step explanation:
Correlation coefficients show if there is a strong or weak positive or negative relationship, or if there is no relationship between the variables.
Correlation coefficients are negative when the relationship is inversely proportional and positive when the relationship is proportional.
Correlation coefficients can be any value less than or equal to 1 or greater than or equal to -1.
Answer:
x = 3
Step-by-step explanation:
cambia los signos : x - 2x-1=8-3x-3
like terms : -x-1=5-3x
variable: -x+3x=5+1 --> 2x=6
dividir: x=3
Answer:
yes
Step-by-step explanation:
Answer:
Step-by-step explanation:
This is function composition. We will take the g function and plug it into the f function wherever we see an x. That will look like this when it's done but before it's simplified:
and that can be simplified down to
The domain of this function will be all real numbers EXCEPT for the one(s) that cause the denominator to become undefined. Set the denominator equal to 0 and solve for x:
5x - 4 = 0 so
5x = 4 and
x = 4/5
In other words, D = {x | x ≠ 4/5}
