State whether the data described below are discrete or continuous, and explain why the durations of movies in minutes a choose the correct answer below oa. the data are continuous because the data can take on any value in an interval. st o b. the data are continuous because the data can only take on specific values oc. the data are discrete because the data can take on any value in an interval. o d. the data are discrete because the data can only take on specific values. g d

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
