A group of 8 students was asked, "How many hours did you watch television last week?" Here are their responses: 7, 20, 8, 15, 10

Musya8 [376]

To find the mean you add up all the numbers and divide that amount by the amount of numbers. Which looks like this:
7 + 20 + 8 + 15 + 10 + 17 + 7 + 13= 97
97 divided by 8 = 12.125

The mean is 12.125.

To find the median you first need to put the numbers in order and then try to find the number in the middle. If there is two numbers in the middle those two numbers are still the median:
7, 7, 8, 10, 13, 15, 17, 20,

The median(s) are 10 and 13.

Answer:

$y=9,x=4$

Step-by-step explanation:

System of equations:

$x+y=13$

$60x+80y=960$

_____________

simplify:(isolate x)

$x=$ $\frac{4(-y+12)}{3}$

$x+y=13\\$

substitute equation for x into second equation:

$\frac{4(-y+12)}{3} +y=13\\$

simplify:

$\frac{-y+48}{3}=13\\ y=9\\$

substitute y into equation for x:

$x=4$

Steps are shown in the graph.

However, to type them out here:

Write down a function of x: $y(miles)= (miles \cdot 0.30) +$ daily rental cost

Then place the numbers in: $y(20)=x(0.30) +20\\y(20)=26$
