Aturntable rotates at  68  revolutions per minute. what is its angular speed in radians per second?

I'll give brainliest if you answer right : )

40 describe the outliers from the scatter plot.

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0
