Answer: 25%
Step-by-step explanation: To find the percent increase, we divide the amount of change by the original number.
The amount of change is the difference between the two numbers which in this case is 375 - 300 and the original number is 300.
.
375 - 300 is 75 so we have 75/300 which is 0.25 as a decimal.
Now, remember we want to find the <u><em>percent</em></u><em> </em>increase so we need to write 0.25 as a percent.
We do this by moving the decimal point 2 places
to the right to get 25%.
So when a number changes from 300 to 275, it's increasing by 25%.

<h3>What are the parameters of a random variable?</h3>
A function of random variables utilized to calculate a parameter of distribution exists as an unbiased estimator.
An unbiased estimator exists in which the difference between the estimator and the population parameter grows smaller as the sample size grows larger. This simply indicates that an unbiased estimator catches the true population value of the parameter on average, this exists because the mean of its sampling distribution exists the truth.
Also, we comprehend that the bias of an estimator (b) that estimates a parameter (p) exists given by; E(b) - p
Therefore, an unbiased estimator exists as an estimator that contains an expected value that exists equivalent to the parameter i.e the value of its bias exists equivalent to zero.
Generally, in statistical analysis, the sample mean exists as an unbiased estimator of the population mean while the sample variance exists as an unbiased estimator of the population variance.
Therefore, the correct answer is an unbiased estimator.

I think it would be 5/7 because it says that square B is 5/7 of square A.
