Spring is a peak time for selling houses. The file Spring Houses contains the selling price, number of bathrooms, square footage, and number of bedrooms of homes sold in Ft. Thomas, Kentucky, in spring 2018 (realtor. com website) Click on the datafile logo to reference the data. DATA file a. The Excel output for the estimated regression equation that can be used to predict the selling price given the number of bathrooms, square footage, and number of bedrooms in the house: SUMMARY OUTPUT Regression statistics Multiple R 0.7429 R Square 0.5519 Adjusted R Square 0.4907 Standard Error 61948.6931 Observations 26 ANOVA dr SS 1.0397E+11 8.4428E+10 1.8840E+11 Regression Residual Total 9.0306E+00 MS 3.4656E+10 3.8376E+09 Significance F 4.3455E-04 3 22 25 Intercept Baths Sq Ft Beds Coeficients Standard Error -5531.0144 67312.9506 -1386.2100 23143.8052 60.2793 23.6813 4787077 3401.7K02 Star -0.0822 -0.0599 2.5562 2.3813 P-value Lower 959 Upper 95% 0.9353-145129.5298 134067.5011 0.9528 -19383.5243 46611 1014 0.0180 11.3748 109.1838 002 4L141104611.0095 Does the estimated regression equation provide a good fit to the data?

After a dreary day of rain, the sun peeks through the clouds and a rainbow forms. you notice the rainbow is the shape of a parabola. the equation for this parabola is y = -x2 + 36. graph of a parabola opening down at the vertex 0 comma 36 crossing the x–axis at negative 6 comma 0 and 6 comma 0. in the distance, an airplane is taking off. as it ascends during take-off, it makes a slanted line that cuts through the rainbow at two points. create a table of at least four values for the function that includes two points of intersection between the airplane and the rainbow. analyze the two functions. answer the following reflection questions in complete sentences. what is the domain and range of the rainbow? explain what the domain and range represent. do all of the values make sense in this situation? why or why not? what are the x- and y-intercepts of the rainbow? explain what each intercept represents. is the linear function you created with your table positive or negative? explain. what are the solutions or solution to the system of equations created? explain what it or they represent. create your own piecewise function with at least two functions. explain, using complete sentences, the steps for graphing the function. graph the function by hand or using a graphing software of your choice (remember to submit the graph).
