Answer:
40 students
Step-by-step explanation:
16 = 40%
Divide by two to get 20% = 8
Then multiply by 5 to get 40 = 100%
There’s other ways to do this, BUT this is the way that I solve it.
M= A- 3y
And it’s that bc I did I on the test
Answer:
4 hours
Step-by-step explanation:
Let the size of whole wall be x.
Given that
Ralph painted 1/6 of a wall in 2/3 hours
thus, writing it in mathematical form we have,
time taken to pain 1/6 of x = 2/3 hours
=>time taken to pain x/6 wall = 2/3 hours
since, we have taken size as x so to find time to pain x size of wall ,
we divide both side by 6
=>time taken to pain x/6 * 6 wall = 2/3 *6 hours
=> time taken to pain x wall = 4 hours
Thus, It will take 4 hours to paint whole wall
Answer:
Average waste per day per person =1.51 pounds
Step-by-step explanation:
In 2010 do United States has a population of 309 million people. Also in the year 2010, do United States recycled 170,000 million pounds of waste.
We have to find the the average waste per person per day.
In a year there are 365 days.
In a day, the average amount of waste produced =
= 
= 465.75 million pounds of waste
To find the average amount of waste produced per person per day, divide the average amount of waste produced per day by the total number of people in the country.
Average waste per day per person = 
= 1.51 pounds

Step-by-step explanation:</h3>
The average of a data set is the number "in the middle" of all of the numbers. This is a measurement of the center of a data set. Another word for average is mean.
How to Calculate the Average
The average or mean is calculated by adding all of the values together. Then, divide this sum by the number of data points. For example, if the sum of 5 different data points is 10, then the average would be 10/5.
Finding the Average
Now, let's find the average of this specific data set. First, add all of the data together.
- 30+35+40+41+42+45+47 = 280
Then, count the number of terms. There are 7 different terms within this data set. So, next divide the sum by the number of terms.
This means that the average of the set is 40.
Other Measurements of Center
The mean is not the only measurement of center. There are 3 common measures of center.
- The mean is found by adding all the terms and then dividing by the number of terms.
- Another measurement is the median is found by ordering the terms from least to greatest, and then taking whatever number is left in the middle. The median of this set is 41.
- Finally, the mode is the term that appears the most often. Many times there can be more than one mode. This set has no real mode because all of the terms only appear once.
