Answer:
The correct option is C.
Step-by-step explanation:
Given that Carlos operates a helicopter. Carlos decides to measure the rotational velocity of the helicopter blades. we have to find the appropriate unit for Carlos's purpose.
The angular velocity ω is the rate of change of angle with respect to time,
The formula to find the rotational velocity is
Angle measure in radians or degrees and time in second.
Hence, the appropriate unit for Carlos's purpose is degrees per second.
The correct option is C.
D. 68
I don’t remember what formula this is called but the formula says that all angles in a triangle should add up to 180, so 75+37= 112, 180-112= 68
Answer:
The 90% confidence interval is 0.575 to 0.625.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence interval , we have the following confidence interval of proportions.
In which
Z is the zscore that has a pvalue of .
For this problem, we have that:
90% confidence interval
So , z is the value of Z that has a pvalue of , so .
The lower limit of this interval is:
The upper limit of this interval is:
The 90% confidence interval is 0.575 to 0.625.
