Answer:
its B:No, the face’s dimensions are 4 m by 4 m, so the area is 16 m2.
Sample answer from Edmentum
Answer:
D = (9.6,0). AC is horizontal with y=0 at all points on AC. Also, because BD is an altitude, it forms a right angle with AC, so BD is a vertical line. For all points on BD, x= 9.6.
Hope this helps, have a good day (:
Answer:
First one Equivalent but not simplified fully (Can combine the two y terms)
Second: Equivalent but not simplified fully (Can combine the two x^2 terms)
Third: Equivalent and simplified fully
Fourth: Not equivalent (y term is not correct)
Fifth: Not equivalent (x^2 term is not correct and the constant terms [ones without variables] can be combined)
Sixth: Not Equivalent (y term is not correct and the constant terms can be combined)
Step-by-step explanation:
You just need to know if two terms have the same variable they can be added or subtracted. But if it is say x and x^2 it cannot, they need to be brought to the same power as well. or if there is a term with xy, it can only be added and subtracted to other xy terms
Answer:
32+8k
Step-by-step explanation:
multiply both sides by the number outside parenthesis
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.
