Hello using PEMDAS I came up with 63
division and multiplication first then add and subtract leaving you with 63

Answer:
The equation of the regression line for the following data is:
y=2.4x+120.1
Step-by-step explanation:
We are given a set of data values in table form as:
             Day(x)                  Number of visitors(y)
                1                              120
                2                             124
                3                             130
                4                              131
                5                              135
                6                              132 
                7                              135 
Hence, when we draw a scatter plot with the help of these data points using the linear regression calculator we see that the regression line is a line with y-intercept as (0,120.1) and x-intercept as  (-50.04,0)
Hence, the regression line for the following data is:
                    y=2.4x+120.1
 
        
                    
             
        
        
        
Answer:
2.25π square inches
Step-by-step explanation:
Area = π
Diameter = 2r
So in this case, radius = 1.5 inches
Plugging that into the area formula produces the answer
