in a continuous data the median class is 40-50. If the cumulative frequencies of the premedian class is one half of the sum of the frequencies. Find the median.

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.

What is the value of n in the equation -1/2(2n+4)+6=-9+4(2n+1)
