Answer:
a) Any sample statistic used to approximate a population parameter.
Step-by-step explanation:
An unbiased estimator is any sample statistic used to approximate a population parameter.
In mathematics, the bias of an estimator refers to the difference between the true value of the parameter being estimated and the estimator’s expected value.
If a statistic is not an underestimate or overestimate of the population parameter, then it is unbiased.
That is why an unbiased estimator is an accurate sample statistic used to approximate a population parameter.
Answer:
The answer is E = 2 volts.
Step-by-step explanation:
i) The maximum number of volts across a resistor R = E volts
ii) The value of the resistance, R = 200 ohms
iii) The value of the power absorbed by the resistor in watts, P = 2 watts.
iv) The formula for the power absorbed by a resistor is given by
P = R =
v) Therefore
vi) therefore from the formula for the voltage drop across resistor we get
E = I R = 0.01 200 = 2 volts.
vii) Therefore E = 2 volts.
Answer:
its 5 can you answer mine please
Cutting through open fields. Taking the path is 12 miles. By cutting through it, he is cutting in the middle. Half of 12 is 6. So it would be around 6 miles to get to the park with this shortcut.
Hope this helps, sorry if it doesn’t make sense.
