First you want to put them in order from least to greatest. 65, 72, 74, 75, 86, 89, 93, 95, 96, 97, 100. Now you count the numbers on the left and right until you get to the middle, there is an uneven number so therefor you wont have to do any extra math. 65, 72, 74, 75, 86, 89, 93, 95, 96, 97, 100. there is 5 on each side 89 being the median. Now moving onto the mode. You will need all of them for this not taking out the ones of there being multiple. 95, 95, <span>96, 100, </span>86, 75, 75, 75, 74, 72, 89, 97, 93, 65 You need to find the number that there is the most of to find the mode. to do this keep score of how many of each of the numbers there is 95, 95, 96, 100, 86, 75, 75, 75, 74, 72, 89, 97, 93, 65 The most commonly occuring number is 75 in this dataset. Reviewing our answers. In the end the median is 89 and the mode is 75
First let's calculate the mode. The mode is the more repeated data. For our set of data we have that 75 is written three times, the other data are written twice or once. Then, 75 is the mode.
Now, to find the median we need to organize the data from least to greatest.
65 72 74 75 75 75 86 89 93 95 95 96 97 100
as we have an even number of items we take the two middle terms, in this case 86, 89 and find the average value.
(86+89)/2 = 175/2 = 87.5. Then, the median is 87.5.
C. 38.46% To get your answer you divide the number of students who liked sandwiches by total number of students in the cafeteria. Example: 10/26=.3846 which is 38.46%
that would be the answer for how many books he got for free because if there is a box of 16 books and for every2 books you get one free then you would divide 16 and 2 and get 8 then
16+8=24
add the number of books he got for free with the original 16 books he already had and get 24 total books.
