Answer:
the mean is 12.6 and the median is 12
Step-by-step explanation:
to find the mean add all the values together and divide by the total amount of values, in this case is 9
to find the median, line up all numbers in order from smallest to largest, and the middle value is the median in this case is 12
Answer:
(9, 6)
Step-by-step explanation:
add equations together: (x + y = 15) + (x - y = 3) --> x + x + y - y = 15 + 3 --> 2x = 18
isolate the variable: 2x/2 = 18/2 --> x = 9, so the x-coordinate is 9
substitute 9 in x's place in one of the equations: 9 + y = 15
solve for y: y = 15 - 9 --> y = 6, so the y-coordinate is 6
combine x and y coordinates together: (9, 6)
Surface area=2(legnth times width)+2(legnth times height)+2(height times width)
this is because there are 6 faces and 2 are idencical, assuming this is a regular rectangular prism.

SA=2(413 times 477)+2(413 times 729)+2(729 times 447)=2(197001)+2(301077)+2(325863)=394002+602154+651726=1,666,842
the surface area is closest to D
In a right triangle, the hypotenuse is √2 x the legs. In this case, the value of x is .
