the velocity, vm/s, of a particle moving in a straight line, at time t seconds is given by
v=1+9/t^2
for 1 is less than or equal to t which is less than or equal to 3. when t=3, the particle is 6m from a fixed point o
on the line.
find the acceleration when t=2
find an expression in terms of t for its distance from the fixed point.
find the distance travelled between t = 1 and 1 = 3.

In this problem, we explore the effect on the standard deviation of multiplying each data value in a data set by the same constant. consider the data set 14, 6, 8, 15, 15. (a) use the defining formula, the computation formula, or a calculator to compute s. (round your answer to one decimal place.) s = 4.28 (b) multiply each data value by 3 to obtain the new data set 42, 18, 24, 45, 45. compute s. (round your answer to one decimal place.) s = 12.83 (c) compare the results of parts (a) and (b). in general, how does the standard deviation change if each data value is multiplied by a constant c? multiplying each data value by the same constant c results in the standard deviation remaining the same. multiplying each data value by the same constant c results in the standard deviation being |c| times as large. multiplying each data value by the same constant c results in the standard deviation increasing by c units. multiplying each data value by the same constant c results in the standard deviation being |c| times smaller. (d) you recorded the weekly distances you bicycled in miles and computed the standard deviation to be s = 3.8 miles. your friend wants to know the standard deviation in kilometers. do you need to redo all the calculations? yes no given 1 mile Γ’β° 1.6 kilometers, what is the standard deviation in kilometers? (enter your answer to two decimal places.)
