3. Which equation best models the data in the table below? 30
Time (minutes)
Height (feet)
10
2120
20
1640
40
680
1160
O y= - 10x - 2120
O y=10x – 480
O y= - 48x + 2120
O y= - 48x + 2600

Aci is desired for the true average stray-load loss μ (watts) for a certain type of induction motor when the line current is held at 10 amps for a speed of 1500 rpm. assume that stray-load loss is normally distributed with σ = 2.3. (round your answers to two decimal places.)
