Answer:
Q. Find the range and coefficient of range of the data :
- 100 , 200 , 400 , 600 , 900
⇾ Solution :
- largest value ( L ) = 900 & smallest value ( S ) = 100
We know , Range is the difference between the largest and smallest value. By definition ,
1. Range = Largest value - Lowest value = 900 - 100 = 
2. Coefficient of range =
Q. If f ( x ) = 9x - 8x and x belong to { 0 , 4 , 3 ,5 }. Find the range.
⇾ Solution:
When x = 0 , f ( 0 ) = 9 × 0 - 8 × 0 = 0
When x = 4 , f ( 4 ) = 9 × 4 - 8× 4 = 4
When x = 3 , f ( 3 ) = 9 × 3 - 8 × 3 = 3
When x = 5 , f ( 5 ) = 9 × 5 - 8 × 5 = 5
- Range = { 0 , 4 , 3 , 5 )

Step-by-step explanation:
Answer:
square root of 34
Step-by-step explanation:
ok so S is for Squared
Cs= As+Bs
5s+3s= Cs
25+9=34
Cs=34
C= square root of 34
to get C we need to square root Cs
square root of 34
so C is 5.83
Answer:
Rational
Step-by-step explanation:
5.74 is the same as 5.74 over 1. In other words, 5.74 can be written with a numerator and denominator, like this:
5.74 = 5.74/1
5.74 x 100/ 1 x 100
You can multiply the numerator and denominator of any fraction by the same number and keep the value of the fraction the same. Here we will multiply the numerator and denominator by 100 to get rid of the decimal point.
5.74 × 100/ 1 × 100
When we calculate the numerator and the denominator above, we get this fraction:
574/100
The fraction above is the same as 5.74. Furthermore, the numerator and the denominator of the fraction above are integers. Therefore, we can conclude that the answer to "Is 5.74 a rational number?" is yes.
