Answer:
X=32152
Explanation:
Given that
Mean ,μ=40,839 miles
Standard deviation,σ = 4,056 miles
We know that
Given that
When P= 0.02 then Z=-2.053 (From standard chart)
X=32512.032 ≅32512
X=32152
so the guaranteed mileage is X=32152
The voltage provided by the power supply = 20 V
<h3>Resistors in series </h3>
The Voltage across resistors in series in a circuit is equal to the sum of the voltage drops across each resistor.
Therefore for two resistors in series the total voltage provided by the power supply is equivalent to the summation of the voltage drops acroos each resistor ( i.e 10 V + 10 V = 20 V )
Hence we can conclude that the voltage provided by the power supply is 20 V
