Answer:
176 seconds
Step-by-step explanation:
By using regression line calculator,
Equation of the line of best fit will be,
T = -12.55x + 276.52
Here , T = time taken to cover one lap
x = Age
If the age of Marsha's son is 8 years then expected time taken by her son to cover one lap will be,
T = -12.55(8) + 276.52
T = -100.4 + 276.52
T = 176.12 seconds
Therefore, approximate time taken by Marta's son will be 176 seconds.
The answer is D. 3/4
A proper fraction is less than one, with the numerator less than the denominator.
