Jim surveyed the students in his school about the number of hours they watch T. V. each night. In his analysis, he stated that the range was 6 and the mean was 2. What conclusion can you draw? A. While the typical student watches 6 hours of TV a night, the difference between the highest number of hours and lowest was 2 hours.

B. While the typical student watches 2 hours of TV, half watch less than 6 hours.

C. On average, students watched 2 hours of TV, and there was a 6-hour variation in viewing times.

D. Most students watch 2 hours of T. V. or less.

C.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1
