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.

Answer:
$9.38
Step-by-step explanation:
halibut is measured in pounds and a portion is measured in ounces
in order to determine the cost, the two units have to be comparable. So, ounces have to be converted to pounds
1 ounce = 0.0625 pounds
6 ounces = 0.0625 x 6 = 0.375 pounds
0.375 pounds would cost 0.375 pounds x 25 pounds = $9.38
