Answer:
The correct answer is A. Both samples are dependent samples.
Step-by-step explanation:
Both samples are dependent samples, since to verify the effects of one, it is necessary to compare it with the effects and characteristics of the other.
Thus, in the case, it is intended to check the effects of caffeine on taste by using a regular soda sample first, and then comparing it with a decaffeinated soda sample. Therefore, the effects of one sample will be checked and compared with the other sample, so that there is a dependency relationship between the two, since neither could prove the hypothesis on its own.
I think you mean the greatest common factor to factor
this is useful because say you want to divide 100 by 1000 then the common factor is 100 so factor that out and get 1/10
so just find the factors or the whole numbers that multiply to get those numbers exg
factors of 18=2*3*3
note:2*3 means 2 times 3
so just find the factors and group the common ones exg
896 and 322
factor
896=2*2*2*2*2*2*2*7
644=2*2*7*23
we see that 2*2*7 is common to both so the greatest common factor is 2*2*7=28
Answer:
y= x/4 +4
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
2x + y = 20
y = 20 - 2x
Substitute into second equation:
6x - 5(20-2x) = 12
6x -100 +10x = 12
16x = 112
x = 7
Plug back into first equation:
2(7) + y = 20
14 +y = 20
y = 6
Answer is x = 7 and y = 6
Answer:
No.
Step-by-step explanation:
According to the law of exponent:-
Therefore:-
