150 books-86 books= 64 books.
We originally have 86 books, so the percent of increase is:
64 books/ 86 books* 100%= 74.42%
The percent of increase is 74.42%~
Answer:
4.50 yr
Step-by-step explanation:
I assume that this is compound interest.
The compound interest equation is

You don't give the frequency of compounding, so I assume that it is once per year.
Data:
A = ₹117 000
P = ₹90 000
r = 6 % = 0.06
n = 1
Calculations:


Divide each side by 90 0000

Take the logarithm of each side
log1.3 = tlog1.06
0.1139 = 0.025 31t
Divide each side by 0.025 31
t = 4.50 yr
You can buy your magic carpet in 4.50 yr.
Such numbers are not possible.
You can have -4 and 3 or -3 and 4 multiplied with each other to multiply to -12, but if you want to subtract them then you will get 7 or -7.
If you wanted to add them together, then the numbers are -4 and 3.
The main difference between sample results and population results is that sample results are less accurate than the population results.
Given nothing and we are required to give the difference between the sample and population results regardless of how well the sampling plan has been designed.
Sample is basically a small part of whole population.
Population is basically includes each unit in the space regarding which the data is to be collected for the research.
The main differences between the sample and population results regardless of how well the sampling plan has been designed are as under:
- To collect data of whole population the researcher needs huge money and time whereas in sampling the researcher devotes comparatively less time than data collcection through population.
- The data collected through population is more accurate than data collected through sample because sample is just a representation of population and there may happen that there are units different from the sample in the population.
Hence the main difference between sample results and population results is sample results are less accurate than the population results.

I think it would be 4x^2 and 3x^3 because they both have the same "x". Because you can't add, for example, 5x + 7z, they aren't alike. That's why you have to choose like terms, for example, 5x+ 5x= 10x.
