Please help how do i find the area of the shape?
Orlov [11]

Answer:

Do not listen to the other answer! Here is how you solve that.

Step-by-step explanation:

For the semicircle, here is the formula for area: A= \frac{1}{2}(\pi r^2)

For the triangle, here is the formula for area:A=\frac{1}{2}(bh)

Then, add.

So,

Triangle:

A=\frac{1}{2}(9*12)

A=54

Semicircle:

A=\frac{1}{2}(\pi 6^2)

A=18\pi

Your answer is Area = 54 + 18\pi

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.
