If a number is rational it means, it can be written in the form of 
, where q≠0 and p and q can be any integers.
There are following properties possessed by Rational numbers
1. Decimal representation of Rational numbers are either terminating or non terminating repeating i.e if the denominator is of the form 
where m and n are any natural number.
2. Addition ,Subtraction ,Multiplication and Division of two rationals is always Rational.
3. The sum or difference of rational and irrational is always irrational.
Answer:
15/56
Step-by-step explanation:
5 people have a license
3 people don't
? = Probability that first person has a license and second does not
We can divide the problem into two sections, the first being the probability of the first person having a license, and the second section is the probability that the second person doesn't have a license.
P1 = Probability of the first person having a license, there are 5 out of 8 person having a license, thus P1 = 5/8.
P2 = Probability of the second person having a license. There are 3 people not having a license, out of 8-1 = 7 persons available, since one is taken already from the first choice, therefore P2 = 3/7.
P1 and P2 are dependent events, thus P(1,2) = P1 * P2.
P(1,2) = P1 * P1 = 5/8 * 3/7 = 15/56
Answer:
Following are the solution to the given point:
Step-by-step explanation:
Grade of students:
Grade of student:
In point a:
Grade of 
students:
Since the Grade of student's variance is higher than 
grade,
In point b:
Please find the attached file.
The plot above shows that the student of the ninth grade is spread more widely, as the student from 0-8 to 12 is from 0-4.
Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.
5 1/3
8 sits in the ones (1) column.
5 sits in the tenths (1/10) column.
4 sits in the hundredths (1/100) column.
-----------------------
Now the four tells us that the number you've mentioned
has 4/100 in it.
0/100 < 4/100 < 10/100
But, 4/100 is closer to 0/100.
Therefore, 8.54 rounded to the nearest tenth is 8.5.
