The benefit of actually growing up.
Answer: 10 students
Explanation:
Students younger than 10 = 50%
Students that are 10years old = 1/20 = 1/20 × 100 = 5%
Students that are older than 10 but younger than 12 = 1/10= 1/10 × 100 = 10%
Students that are 12 years or older
= 100% - (50% + 5% + 10%)
= 100% - 65%
= 35%
This means that 35% of the students are 12 years or older and we've been given the number as 70.
Let's say the total number of students is x. Therefore,
35% of x = 70
0.35 × x = 70
0.35x = 70
x = 70/0.35
x = 200
The total number of students is 200.
Therefore, the number of students that are 10years will be:
= 1/20 × 200
= 10 students
Therefore, 10 students are 10 years.
Answer:
You may use a different variable type for input in order to process the data appropriately and may use a different variable type to accommodate your program.
Explanation:
Your input may have to be different then output varying on what data you are processing.
For example, just like the last question you asked about calculating the area of the rectangle, your input MUST be converted to a different a numerical data type (i.e int or float) in order to do the math.
Based on your last question, if we didn't convert your input into a string your results wouldn't add the numbers together but only concatenate them. If I typed 3 & 5 as length & width, I would get 35 instead of 15.
Now another example is using functions (or methods whatever you want to call them), your input can be one thing and outputs another.
Let's say I want a function to tell me if I am smart. The way I want it to determine if its smart is by inputting my GPA into it, which is a numerical value. So the function would look something like this:
<u>Code (Python)</u>
def IsSmart(gpa):
if (gpa >= 4):
return True
else
return False
As you can see I am inputting a numerical value and it is outputting a boolean value. I can use this in a if else chain to spit out an output to the user.
