Answer:
your inequality signs are correct so i'll skip those
-2.06, .9803
.67, .7486
Step-by-step explanation:
1.)
To do this one you need to standardize x by subtracting the mean and dividng by the standard deviation
(1000-3262)/1100= -2.056 which i will round to -2.06
with this as our z value use the table to find the associated probability
.9803
2.)
Same process
(4000-3262)/1100=.67
which has a probability of .7486

Answer:
Adrian's songs played on 9 commercials and 5 movies.
Step-by-step explanation:
Let x denotes number of commercials and y denotes number of movies.
Total number of commercials and movies = 14
