A realtor is trying to predict the selling price of houses in Greenville (in thousands of dollars) as a function of size (measured in thousands of square feet) and the number of bedrooms (BR). Part of the regression output is provided below, based on a sample of 20 homes. Some of the information has been omitted. The estimated coefficient for Size is approximately
Variable Coefficients Standard t-Stat
Error
Intercept 13 4.5
Size 2.2 2.1
BR 6.8 2
a. 4.6
b. 1.0
c. 6.6
d. 6.2

estimated coefficient for size = 4.6

Step-by-step explanation:

We have given that

Variable               Coefficients           Standard           Error t-Stat

Intercept                  13                                                        4.5

Size                                                          2.2                      2.1

BR                             6.8                           2

The standard error = 2.2

T stat= 2.1

Formula:. t stat = estimated coefficient/ standard error

Estimated coefficient= t stat* standard error

Estimated coefficient= 2.1*2.2

                                   =4.62

                                    ≈4.6

Thus, estimated coefficient for size = 4.6

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.

step-by-step explanation:

i googled it and this is what i got i don't know how it is. sorry.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
