Answer:
36
Step-by-step explanation:
Wilson records 9 violet chips and 16 red ones.
So from a sample of 25 chips, 9 are violet.
So violet probability out of 25 = 9/25.
If we make a proportion we find how many violet chips out of 100 = 36
9/25 = ?/ 100
?= 36
Answer:
5n=c
Step-by-step explanation:
the equation 5n=c can represent the total cost Hong would have paid for the notebooks because given that each notebook costs $5, you would multiply 5 by the number of notebooks (n) that Hong would be purchasing, which would bring you to the cost (c) of the notebooks all together

Answer:
(A) 6/20 = x/2000
Step-by-step explanation:
To complete your questions, the missing parts are shown below
Sample 1 Sample 2 total
Country 5 3 8
Pop 4 3 7
Classical 3 5 8
Jazz 2 4 6
Rock 6 5 11
Total 20 20 40
The proportion that would predict the number of jazz songs that Mr. McElroy has stored on his MP3 player is given by 6/20
Hence, our required proportion would be
6/20 =x/2000
We cross multiply
20x = 2000 x 6
20x = 12000
Divide both sides by 20
X = 12000/20
X = 600
Hence, our required proportion would be
6/20 = x/2000
