Answer:
The interest rate was 42.5%.
Step-by-step explanation:
75:3 is equivalent to 25:1 or just 25
By following the pattern the next image in the pattern is (b) since the correct option is (b).
A recurring arrangement of numbers, forms, colors, and other elements constitutes a pattern in mathematics. The Pattern can be connected to any kind of occasion or thing. When a group of numbers is arranged in a particular way, the arrangement is referred to as a pattern.
From the pattern given: In pattern one, the first column contains 2 blocks and the second column contains 1 block. In pattern second, the first column contains 3 blocks, the second column contains 2 blocks and the third column contains 1 block. In pattern third, the first column contains 4 blocks, the second column contains 3 blocks, the third column contains 2 blocks and the fourth column contains 1 block.
∴ You can observe that block the ks are arranged in descending numbers.
Hence, option (b) is correct.

Answer:
The triangle is isosceles and not right
Hope this helps.
Answer:
Is not appropiate to refer a estimation or a statistic as a paramter because the statistic just give informaation about the sample selected and not about all the population of interest. What we can do is inference with this sample proportion or confidence intervals in order to see on what limits our real parameter of interest p lies.
Step-by-step explanation:
Description in words of the parameter p
represent the real population proportion of students who went Home for winter break
represent the estimated proportion of students who went Home for winter break
n is the sample size selected
The population proportion have the following distribution
Solution to the problem
For this case we assume that the proportion given 0.35 is an estimation for the real parameter of interest p, that means 
On this case the estimated proportion is calculated from the following formula:

Where X are the people in the sam with the characteristic desired (students who went Home for winter break) and n the sample size selected.
