Final answer:
To forecast for week 3 using the equation y = 1.8x + 5, substitute x with 3 and solve to get 5.4 + 5, which equals 10.4.
Step-by-step explanation:
To forecast for week 3 using the equation y = 1.8x + 5, where x is the time in weeks, you would substitute the value of x with 3.00 as follows:
y = 1.8(3.00) + 5
First, multiply 1.8 by 3.00:
1.8 × 3.00 = 5.4
Then, add 5 to the result:
5.4 + 5 = 10.4
Thus, the forecast for week 3 would be 10.4. This process employs the equation's parameters to project values based on time, demonstrating a straightforward approach to forecasting and estimating outcomes, valuable in various analytical and predictive models across diverse fields like economics, science, and trend analysis.
