This is one of the photos I used to answer, I’m going to send the second one
Answer:
2/3
Step-by-step explanation:
4/9×3/2=2/3 The answers provided are all wrong
False if y=f(x) then x= inverse of f(x) or f^-1(x)
So I’m only answering so I can ask you a question
Answer: (a) 9
Step-by-step explanation:
We are given that ,
The first two classes of a frequency distribution are 0-9 and 10-19.
We know that the class width of an class interval is basically the difference between the upper limit and the lower limit of the interval.
For example the class interval for interval 40 - 45 is 5 because 45-40=5.
For the given class interval 0-9 , upper limit= 9
Lower limit =0
⇒ Class width = 9-0= 9
Similarly , for 10-19 , the class width = 19-10=9
Therefore , the class width is 9 .
Hence, the correct answer is (a) 9.
