Answer:
Time taken by Stephen = 162 seconds
Step-by-step explanation:
Stephan gathered data which fits in the line of best fit,
y = -2.1x + 565.6
Where x represents the age (in months)
And y represents the time (in seconds) taken by Stephen to run two laps on the track.
Time taken to run 2 laps at the age of 192 months,
By substituting x = 192 months,
y = -2.1(192) + 565.6
= -403.2 + 565.6
= 162.4 seconds
≈ 162 seconds
Therefore, time taken by Stephen to cover 2 laps was 162 seconds when he was 192 months old.
<span>s in (-oo:+oo)
(1/3)*s+14 = 26 // - 26
(1/3)*s-26+14 = 0
1/3*s-12 = 0 // + 12
1/3*s = 12 // : 1/3
s = 12/1/3
s = 36
s = 36</span>
Here is the answer in the picture.
