Step-by-step explanation:
Confidence interval = mean ± margin of error
CI = μ ± ME
The mean is μ = 8.7.
Margin of error = critical value × standard error
ME = CV × SE
At 95% confidence and 9 degrees of freedom, CV = 2.262.
SE = s / √n
SE = 3.3 / √10
SE = 1.04
The margin of error is:
ME = 2.262 × 1.04
ME = 2.36
CI = 8.7 ± 2.36
CI = (6.34, 11.06)
The answer is that you are measuring "resistance".
If the segment is DE-energized, which means the entire device is shut down, at that point the main thing you can quantify with the meter- probes on the two ends of the segment is its resistance. The ordinary meter measures volts, amps, and ohms. If you touch
the probes to the two ends of the part and the circuit is empowered, at that point you measure the voltage over the component. If the circuit is DE-energized, at that point you are measuring the component's resistance.
I would say answer chose C
Answer:
The initial cost of the cell phone was $364
Step-by-step explanation:
Since there was a 30% markup, 70% of the new cost is the initial cost. Multiply 520 by 0.7 on a calculator and you get 364
