Responder:

y = -6X + 36

Explicación paso a paso:

Dados los datos:

CANTIDADES __PRECIO

5 ___ 6

4 ___ 12

3 ___ 18

2 ___24

1 ___ 30

Usando una calculadora de modelo lineal:

La ecuación del modelo lineal obtenida con una calculadora de regresión es:

y = -6X + 36

Donde y = precio; - 6 = pendiente; Intercepción = 36

Se pudo observar que como reducción en la cantidad demandada puede ser como resultado de un aumento en el precio.

For online courses, like those in eCore, there is a positive correlation between the amount of time spent in the course and the
Troyanec [42]

Answer:

Regression Line is given by,

y = 22.909 + 0.209 x

The course grade of a student in the course who spent an average of 103 minutes in the course each week is: 22.909 + 0.209 × 103 = 44.436

Step-by-step explanation:

The equation of Regression equation is of the form of:

y = a + bx

where, a is intercept and b is slope

The formula for a and b is given by,

a=\frac{\sum Y \sum X^2-\sum X \sum XY}{n\sum X^2-(\sum X)^2}\\ and, b = \frac{n\sum XY -\sum X \sum Y}{n\sum X^2-(\sum X)^2}

Here, ∑X = 1149.8, ∑Y = 377.2, ∑XY = 93115.95, ∑X² = 320246.72

Thus, a = 22.909

and b = 0.209

Thus, Regression Line is given by,

y = 22.909 + 0.209 x

Thus, The course grade of a student in the course who spent an average of 103 minutes in the course each week is: 22.909 + 0.209 × 103 = 44.436

Now plotting these line:
