Agroup of students rolled two number cubes 107 times and recorded a sum of seven 10 times. find the experimental probability of rolling a sum of seven. write your answer with a % sign without any spaces rounded to the nearest percent. x

Which expression is equivalent to? assume x > 0 and y > 0.

Which sum or difference identity would you use to verify that cos (180° - ∅) = -cos ∅? a. sin (α -β) = sin α cos β – cos α sin β b. cos (α -β) = cos α cos β – sin α sin β c. cos (α -β) = cos α cos β + sin α sin β d. sin (α + β) = sin α cos β + cos α sin β
