A group of 6 students was asked, "How many hours did you watch television last week?" Here are their responses: 5, 10, 12, 15, 16, 9
Find the mean and median number of hours for these students.
If necessary, round your answers to the nearest tenth.

Mean: 11.2

Median: 11

Mode: There is none

Step-by-step explanation:

mean -you add all the numbers and divide by the number of numbers

median- you arrange the data set by numerical value (increasing) and it is basically the "middle number" for example 1, 2, 3, (2 would be the "middle" number" )

mode- is the number that appears most often. in this scenario, all numbers appear the same amount of times (1) so there is no mode.

Average = 11.2

Median = 11

Step-by-step explanation:

Mean = Average

Average = Sum of the numbers divided by how many numbers are there.

5 + 10 + 12 + 15 + 16 + 9 = 67

There are 6 numbers.

Average rounded to the nearest tenth = 67/6 = 11.2

Median = middle of the numbers in ascending order.

Put the numbers in order and you would get: 5, 9, 10, 12, 15, 16

When there is two medians, find the average of the two.

The average of 10 and 12 is 11.

Median is 11.

Hope this helps :)

Have a spectacular day!

x/3-10=8

x/3=18

x=48

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
