Answer:
(d) I and II
Step-by-step explanation:
The correlation is a measurement of a dependence between 2 variables. If the logarithm of the correlation function shows a linear tendency, it because the correlation between x and y shows a exponential tendency.
This mean that x and y are non linear correlated, but them are correlated.
For this type of data is used a non linear correlation technique know it as logarithm correlation.
Option III is incorrect because random patterns have a correlation value close to 0, which is not the case.
Answer
B
Step-by-step explanation:
because it has to be less than according to the word problem and using common sense I know that if there are more than 1 of a number as an answer choice that means that it is most likely the answer
Your answer is c i took the test it is right

Answer:
El área del rectángulo es:
27 cm²
Step-by-step explanation:
Consideración:
La formula del perímetro de un rectángulo es:
p = 2(altura + base)
Planteamiento:
24 = 2(a+b)
b = 3a
a = longitud de la altura del rectángulo
b = longitud de la base del rectángulo
Desarrollo:
sustituyendo el valor de la segunda ecuación del planteamiento en la primer ecuación del planteamiento:
24 = 2(a + 3a)
24/2 = 4a
12 = 4a
a = 12/4
a = 3 cm
de la segunda ecuación del planteamiento:
b = 3a
b = 3*3
b = 9 cm
Comprobación:
de la primer ecuación del planteamiento:
24 = 2(3+9)
24 = 2*12
Respuesta:
la formula del área de un rectángulo es:
A = base * altura
A = 9cn * 3cm
A = 27cm²
