To find:The height of the building at 6 months.
Answer to Problem 20PFA
The height of the building at 6 months is B.171 ft.
Explanation of Solution
Given information:
The table shows the height of a skyscraper during its construction. Also, use 9 and 18 months to write the equation for the line of fit.
Month ( x ) | 0 | 9 | 12 | 18 | 20 |
Height in feet ( y ) | 26 | 252 | 345 | 495 | 553 |
Calculation:
From the table, consider the points (9,252) and (18,495) to find the equation of the line of fit using two-point form.
So, the equation of the line of it will be given by,
Now,
Therefore, the equation of the line of fit will be,
Now, at 6 months,
Conclusion:
Therefore, the height of the skyscraper will be 171 feet at 6 months.
