Answer:
The correct answer is the last one.
Step-by-step explanation:
Variable data is any kind of information gathered that can be made into a chart or graph representing what was collected. In other words, the data collected must vary.
The first, second, and third answers cannot be made into a chart/graph as it would be a singular number, and not provide varying data (which is required to produce a graph/chart).
The last answer would be correct as one can create a chart as the data collected from that question would vary. For example, five family members could be born in July, six in August, and ten in October. The variable that is "varying" would be these months.
Hope this helps!
1) last number times 4 and subtract 1
2) last number times2 and add 2
3) you figure out
To find a percent you multiply the decimal number by 100. OR to be easier just move the decimal number 2 places to the right.
4.3%
It has infinite solution or many solutions.
The steps are on paper.
We are given with a complex no. and need to simplify it , so let's start !!!
Let's assume that :
Now , Rationalizing the denominator or in other words multiplying and dividing 
by the <em>conjugate</em> of the denominator
Hence , Option B) <em>(8/5) + (6/5)i</em> is correct :D
