Answer:
98.83
Step-by-step explanation:
Since 37° is 37/360th of the full circle, the area of the size of pie will be 37/360th of the full area. The radius is d / 2 = 17.5 so the area is:
37/360 * πr²
= 37/360 * 3.14 * 17.5²
= 98.83
Answer
Cluster sampling. See explanation below.
Step-by-step explanation:
For this case they not use random sampling since we are selecting people from flights. Because we select just 5 random flights.
Is not stratified sampling since we don't have strata clearly defined on this case, and other important thing is that in order to apply this method we need homogeneous strata groups and that's not satisfied on this case.
Is not convenience sampling because they NOT use a non probability method in order to select the people from the flights.
So then the only possible method is cluster sampling since we have clusters clearly defined (Passengers from the airlines), and we satisfy the condition of homogeneous characteristics on the clusters and an equal chance of being a part of the sample, since we are selecting RANDOMLY, the 5 flights to take the information.
Answer:
= -14x
Step-by-step explanation:
Since the equation is saying to subtract 10x, we are going to change the minus sign to a addition sign and change positive 10 to negative and continue the rest.
Angles 5 and 6 are not congruent because they are on the same line, so the answer is I
