Answer:
This is an geometric sequence because the common ratio is -2.
Step-by-step explanation:
-2*-2=4
4*-2=-8
-8*-2=16
So, as we are seeing that the common ratio is -2, so this is an geometric sequence.
If the x between 5 and 2 is a letter then the answer is -21
If it’s a multiplication sign then it’s 19
You do 14 divided by 16 which is 0.875 times by 100
which is 87.5 so that means 14/16 in a percentage is 87.5 %
Answer:324x^3-828x^2-63x+-9\20
Step-by-step explanation:
I am pretty sure the answer is C because that would be the least biased with the most information.
A would be biased because it is only elementary.
D is biased because it is only teachers that worked for a long time
B is fine, but C is better because it has more people.
