Explicație pas cu pas:
a și B sunt invers proporționale cu numerele 12 și 15
Proporționalitate inversă:
a = k / y
Prin urmare ;
a = k / 12 - - - (1)
b = k / 15 - - - (2)
Procent care reprezintă a de la b
a = 100%
b = x
k / 12 = 1
k / 15 = x
Înmulțirea încrucișată:
x * k / 12 = k / 15
x = k / 12 ÷ k / 15
x = k / 12 * 15 / k
x = 15/12
x = 1,25
1,25 * 100% = 125%
Answer:
f(x)= -54x -4
g(x)= -3x -2
f+g)( x)= -54x -4 -3x -2 = -57x -6
Answer:
Tested outcome (difference) is significant.
Step-by-step explanation:
The significance level of 5% (more typically referred to as 95%) corresponds to saying that if an observation at hand is (only) 5% or less likely to have been generated by chance, then it will be accepted as significant. In this example, the p-level (which is the actual probability of the observation being generated by chance) is lower than 5% (0.0421<0.05) and therefore a conclusion can be made that the observed outcome is significant.
An example of an outcome being significant could a drug improving patients's condition in a clinical study.

Step-by-step explanation:
5 and 8 would have the same degree. So would 1 and 4, and 2 and 3, and 6 and 7 (lot's of "and's" because it's lots of the same degrees...)
