There are 4 dots in categories 0 and 1; 9 dots in categories 2 and 3; and 2 dots in categories 4 and 5. The histogram with bar lengths 4, 9, and 2 is the appropriate choice.
<span>Let x denote number of ounces of 30-cent iodine.
Mixing of 50 ounces of 18-cent iodine and x ounces of 30-cent iodine will result in (50+x) mixture of iodine. We want the mixture to be worth 20 cent per ounce.
The value of 50 ounces of 18-cent iodine is of course
50â‹…18=900.
Similarly, x ounces of 30-cent iodine is worth 30â‹…x.
Finally, 50+x ounces of 20-cent iodine will cost (50+x)â‹…20.
30x+50â‹…18=(50+x)â‹…20
30x+900=1000+20x
10x=100
x=10</span>
Answer:
hi the answer would be x= -1 14/15
