Answer:
Step-by-step explanation:
From the information given, you know that your parents paid $13,600 in taxes from their income that was $56,000. The fraction would be:
To simplify this, first you can eliminate two zeros at the end of each number:
Now, you can divide both numbers by 8, which will result in:
According to this, the simplified fraction that shows how much your parents spent on their federal taxes is .
Answer: 601
Step-by-step explanation:
The formula to find the minimum sample size(n) , if the prior population proportion is unknown:
, where E = margin of error ,
= critical z-value for confidence level c.
Given : E = 0.04
Z-value for 95% confidence = 1.96
So, the minimum sample size required =
Hence, the minimum sample size required = 601
Answer:
The inequality that represents the age of the group, "x", is:
Step-by-step explanation:
To express this problem in an inequality we will attribute the age of the members on the group with the variable "x". There are two available information about "x", the first states that every member of the group is older than 17 years, therefore we can create a inequality based on that:
While the second data from the problem states that none of than is older than 54 years old, this implies that they can be at most that old, therefore the inequality that represents this is:
In order for both to be valid at the same time x must be greater than 17 and less or equal to 54, therefore we finally have:
