Answer:
4 people name chocolate
Step-by-step explanation:
Let's first understand the given information.
The survey shows that 40 percent of a finite number of people name chocolate as their favorite flavor of ice cream. Because the survey is reporting a percentage, then 40% means that from 100 people 40 people name chocolate, while the others name a different type of flavor.
Dividing the total of people (100) by the ones who name chocolate (40) then we have:
100/40 = 2.5
Through the above equation we are actually expressing the following:
Total people = 2.5 * (people who name chocolate flavor)
Using this equation if we have now 12 people:
12 = 2.5 * (people who name chocolate flavor)
12/2.5 = (people who name chocolate flavor)
4.8 = people who chose chocolate flavor
Because we can't have 0.8 of a person, then if we have a sample of 12 people, we will expect that 4 of them name chocolate.
Answer: 8 textbooks
Step-by-step explanation:
Sold 40 notebooks = 40 x $4 = $160
$800 - $160 = $640 left to sell
$640/$80 (cost of textbook) = 8 textbooks need to be sold
to do this you would need to shade in 7 out of the 10 rows going horizontally or vertically it doesnt really matter as long as u shade in 7 rows of them
Answer:
1 8/11
Step-by-step explanation:
19/11
11 goes into 19 one time with 8 left over
put the 8 over the denominator
1 8/11
Amount of milk and cream combined = 1/2 + 2/3 = (3 + 4)/6 = 7/6 = 1 1/6
Required amount = 7/6 - 1/4 = 14 - 3 = 11/12
Therefre, 11/12 less water is used than milk and cream combined.
