Some statistics students participated in an experiment that attempted to test their ability to determine the passage of 1 minute (or 60 seconds). Below are the results in seconds. Identify at least one good reason why the standard deviation of this sample would not be a good estimate of the standard deviation of the adult population.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

step-by-step explanation:

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
