The experimental probability of a biased coin landing on heads is 0.6 Freya spins the coin 80 times.

How many times would you expect the coin to land on tails?

What is the rule for reflection across the y axis

If f(x)=2x+2and g(x)=x^3, what is (g•f)(2)

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.
