To find the mean you have to get the average number found by adding all data points and dividing by the number of data points.
Example: The mean of 4, 1, and 7 is (4+1+7)/3 = 12/3 = 4
For median you have to get the middle number which is found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).
Example: The median of 4, 1, and 7 is 4
because when the numbers are put in order (1, 4, 7) the number 4 is in the middle.
To get the mode you have to get the most frequent number which is, the number that occurs the highest number of times.
Example: The mode of {4,2,4,3,2,2} is 2 because it occurs three times, which is more than any other number.
Hope that helps.
If the older brother is 27...27/3=9...+10=19....and 27+19=46. So the math works out, the younger brother is 19.
905=5a
905/5=5a/5
181=a
HOPE THIS HELPS!!!!!!!!!!
Answer:
identity property of addition-
a+0=a
identity property of multiplication-
a*1=a
Step-by-step explanation:
i cant give u an exact answer as u didnt give Micheals answers so i just gave some examples about what addition and multiplication identity property should look like. Identity property's concept is to keep the same identity. Basically, "a" shouldnt change. In addition, to keep a the same all u hv to do is add 0 as anything plus 0 is the same. for multiplication, just multiply by 1. Hope this helps!!
