To solve 493x = 3432x+1, write each side of the equation in terms of base
sleet_krkn [62]

<u><em>Answer</em></u>

= 3.405 × 10⁻⁴

<u>Explanation</u>

If the question is correctly written, then it is very easy.

First, take the like terms on one side.

493x = 3432x+1

493x - 3432x = 1

-2939x = 1

Dividing both sides by -2939 to get the value of x.

x = 1/(-2939)

= - 0.0003405

= 3.405 × 10⁻⁴

Savatey [412]

Answer:

a. y= 130x + 350 + \epsilon

b. The symbol y-bar represents the average price of hotels in the area

Step-by-step explanation:

a. The regression line equation is given by:

y=\alpha x + \beta + \epsilon

Where Alpha represents the slope, Beta represents the intercept with the Y axis, and epsilon represents the random component of the model. Thus,

\alpha = 130 y \beta = 350  Obtaining:

y= 130x + 350 + \epsilon.

b.  In a simple linear regression model the value of y-bar represents the average of all values ​​of y observed. Thus, since y represents the prices of the hotels, then y-bar is the average price of hotels in the area.

Answer:

  33 1/3 lb

Step-by-step explanation:

When the distance between them goes from 8 ft to 12 ft, it is 1.5 times what it was. Then the force will be multiplied by the inverse of the square of this:

  (75 lb)×1/(1.5²) = 75/2.25 lb = 33 1/3 lb

At 12 feet apart, the attraction force is 33 1/3 pounds.
