Add an attachment of the triangles maybe? :)! And i can help
The plane went 100 meters higher than its original height
Given:
The number of cycles is, <em>n</em> (s) = 7.
The number of wheels in the cycle is, <em>n </em>(sw) = 2.
The number of cars is, <em>n</em> (c) = 15.
The number of wheels in the car is, <em>n</em> (cw) = 4.
The obective is to find the total number of wheels.
The total number of wheels is,
Hence, there are 74 wheels in the block.
If there are <em>x</em> bicycles and <em>y </em>cars, the equatioin will be,
Hence, the number of wheels for x bicycles and y cars is 2x+4x.
Answer:
30 and -3
Step-by-step explanation:
30 x -3=-90
30-3=27
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.
