Answer: Inferential statistics
Explanation:
Inferential statistics is defined as the method in which a data sample is taken from population so that inference about basic population can be made. Conclusion about certain characteristic or property of bigger population from small sample is based upon considering sample as guideline for wider group of population.
According to the question,Jonathan is using inferential statistic method for researching about average differences in small airplanes which are owned privately by people. Instead of conducting research on large amount of such planes, he is performing it on ten planes sample with the help of government record.
This group of ten planes are representing major population of small and private planes.Thus, the output remarking about variation in group of ten planes will represent the basic variation present in population of such planes.
Answer:
A 61377
B 87405
Step-by-step explanation:
If sum of the digits of a number is divisible by 3, then that number is also divisible by 3.
Option A:
Given number is: 61377
Sum of the digits = 6+1+3+7+7 = 24
24 is divisible by 3, hence 61377 is also divisible by 3.
Option B:
Given number is: 87405
Sum of the digits = 8+7+4+0+5 = 24
24 is divisible by 3, hence 87405 is also divisible by 3.
Option C:
Given number is: 30898
Sum of the digits = 3+0+8+9+8 = 28
28 is not divisible by 3, hence 30898 is also not divisible by 3.
Similarly, sum of the digits of the numbers in options D, E and F are 8, 22 and 26 respectively, which are not divisible by 3, hence the numbers 6020, 29830 and 75932 are also not divisible by 3.
Sorry I don’t get that one
Answer:
![15.75x^{10}y^{19}](https://tex.z-dn.net/?f=15.75x%5E%7B10%7Dy%5E%7B19%7D)
Step-by-step explanation:
To find the 5th term in the expansion, we first will need to apply the binomial theorem. I have attached an image of the binomial theorem formula due to not being able to type it.
After applying the binomial theorem and simplifying, you should get:
![512x^{18}y^{27}-576x^{16}y^{25}+288x^{14}y^{23}-84x^{12}y^{21}+\frac{63x^{10}y^{19}}{4}-\frac{63x^8y^{17}}{32}+\frac{21x^6y^{15}}{128}-\frac{9x^4y^{13}}{1024}+\frac{9x^2y^{11}}{32768}-\frac{y^9}{262144}](https://tex.z-dn.net/?f=512x%5E%7B18%7Dy%5E%7B27%7D-576x%5E%7B16%7Dy%5E%7B25%7D%2B288x%5E%7B14%7Dy%5E%7B23%7D-84x%5E%7B12%7Dy%5E%7B21%7D%2B%5Cfrac%7B63x%5E%7B10%7Dy%5E%7B19%7D%7D%7B4%7D-%5Cfrac%7B63x%5E8y%5E%7B17%7D%7D%7B32%7D%2B%5Cfrac%7B21x%5E6y%5E%7B15%7D%7D%7B128%7D-%5Cfrac%7B9x%5E4y%5E%7B13%7D%7D%7B1024%7D%2B%5Cfrac%7B9x%5E2y%5E%7B11%7D%7D%7B32768%7D-%5Cfrac%7By%5E9%7D%7B262144%7D)
Our 5th term here is:
which is equal to ![15.75x^{10}y^{19}](https://tex.z-dn.net/?f=15.75x%5E%7B10%7Dy%5E%7B19%7D)
~Hope this helps! Sorry if my answer is confusing at all, it's pretty difficult to explain.~
