Using the equation, Y=1.8X+5. What will be the forecast for week 4.00? Using time as your independent variable.

Answer 1

To forecast for week 4 using the equation \( Y = 1.8X + 5 \), you will substitute \( X \) with 4 (since X is the independent variable representing time in weeks).

So, the calculation is:

\[ Y = 1.8(4) + 5 \]

Calculating it step by step:

1. Multiply \( 1.8 \) by \( 4 \): \[ 1.8 \times 4 = 7.2 \]

2. Add \( 5 \) to \( 7.2 \): \[ 7.2 + 5 = 12.2 \]

Therefore, the forecast for week 4 is \( Y = 12.2 \).
