Timpony school district surveyed a random sample of 606060 middle school students about the amount of time they watch tv. of the students surveyed, 141414 average watching more than 444 hours of tv each day. there are 114311431143 middle school students in the timpony school district. based on the data, what is the most reasonable estimate for the number of timpony school district middle school students who average watching more than 444 hours of tv each day? choose 1 choose 1

267 middle school students  

Step-by-step explanation:

Sample surveyed consists of 60 students.

Of the students surveyed, 14 average watching more than 4 hours of TV each day. That represents 14/60 = 0.23 of the total.

There are 1143 middle school students

Then, a reasonable estimate for the number middle school students who average watching more than 4 hours of TV each day is 0.23*1143 ≈ 267

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

{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
