Each of 6 students reported the number of movies they saw in the past year. this is what they reported. 15,9,13,18,9,6, find the mean and median numbers of the movies that students saw.

mean = 11.66666

median = 11

Step-by-step explanation:

To find the mean, add up all the numbers, then divide by how many numbers

mean = (15+9+13+18+9+6) / 6 = 70/6 = 11 .6666666

To find the median, put the numbers from smallest to largest. then take the middle number.  Since there is an even number, take the two middle numbers and average them

6,9,9,13,15,18

The two middle numbers are 9 and 13

(9+13)/2 = 22/2 = 11

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
