The table shows the estimated number of lines of code written by computer programmers per hour when x people are working. A 2-column table with 6 rows. The first column is labeled people working with entries 2, 4, 6, 8, 10, 12. The second column is labeled lines of code written hourly with entries 50, 110, 160, 210, 270, 320. Which model best represents the data? y = 47(1.191)x y = 34(1.204)x y = 26.9x – 1.3 y = 27x – 4
Answers
Given : Table showing the estimated number of lines of code written by computer programmers per hour when x people are working & option given y= 47 * 1.191ˣ y= 34 * 1.204ˣ y=26.9x - 1.3 y = 27x - 4
To find : Choose the model which best represents the data
Solution:
People Working lines of code
2 50
4 110
6 160
8 210
10 270
12 320
x y= 47 * 1.191ˣ y= 34 * 1.204ˣ y=26.9x - 1.3 y = 27x - 4
2 66.66 49.3 52.5 50
4 94.57 71.44 106.3 104
6 134.14 103.57 160.1 158
8 190.27 150.14 213.9 212
10 269.91 217.64 267.7 266
12 382.85 315.5 321.5 320.
Below 2 0 4 1
on line 0 0 0 2
Above 4 6 2 3
Hence y = 27x - 4 is the best fit
