Mean: add all the values together and divide by how many numbers there are.
Example- 2+4+6+8+10=30
30/5=6. The mean is 6
Median: arrange the numbers in order from least to greatest (counting order). If there is more than one of any number make sure to put them all together. Then find the number in the middle. That's the median. If there isn't one number in the middle, take the two 'middle' numbers, add them together and divide by 2. That will be the median
Ex- 2, 4, 6, 8, 10 median is 6
Ex- 2, 4, 6, 8, 10, 12 6+8=14 14/2=7 median is 7
Mode: what number shows up the most often? Sometimes there might not be a mode if there are no repeated values.
Ex- 2, 4, 6, 6, 8, 10 the mode is 6, it is in the list more than any other number
Range: the difference of the greatest value and least value
Ex- 2, 4, 6, 8, 10 10-2=8. The range is 8
One thing that is the MOST helpful when finding all of these is to put all the numbers in counting order (least to greatest) before you try to do anything!
Sorry I can't be more specific, it's difficult to read the graphs and charts
(-1, 1)
Find the coordinates of the intersection between the lines.
C = cheese
milk is half of cheese....so milk costs 0.5c
meat is 4 times as much as cheese...so meat costs 4c
and $ 48 was spent
so ur equation would be : c + 0.5c + 4c = 48 <=
Answer:
300 students
Step-by-step explanation:
To know the number of students, we must divide the total amount of milk spent by the amount spent for each and in this way we will obtain the value we are looking for, like this (both have the same units of L, so there is no problem ):
30 / (1/10) = 300
that is to say that there are a total of 300 students
