Let b>a,
a+b=40 so we can say a=40-b
We are told that b-a=6.5, using a found above in the equation gives us:
b-(40-b)=6.5
b-40+b=6.5
2b-40=6.5
2b=46.5
b=23.25, and since a=40-b
a=40-23.25
a=16.75
So a=16.75 and b=23.25
check...
16.75+23.25=40, 40=40
23.25-16.75=6.5, 6.5=6.5
1/3 because there are 3 people and only one correct answer
Answer:
A class has been omitted.
Explanation:
Given the frequency distribution shown in the attached table.
the frequency distribution is incorrectly constructed because a class has been omitted.
On the given table the class 133-137 is missing on the frequency distribution table.
There are several important information's already given in the question. Based on those given information's the answer to the question can be easily deduced.
Number of stamps that Ira has in his stamp album = 128
Number of pages that the stamp album has = 8
Then
Number of stamps in each page of the stamp album = 128/8
= 16
So 16 stamps are there on each page of the stamp album. I hope the procedure is clear enough for you to understand. You can always use this method for solving similar type of problems in future without requiring any additional help.
I am not really that great with that but try googling it, it should pop up somehwere, sorry in advance.
