A recording company obtains the blank CDs used to produce its labels from three compact disk manufacturers: I, II, and III. The quality control department of the company has determined that 1% of the compact disks produced by manufacturer I are defective, 7% of those produced by manufacturer II are defective, and 3% of those produced by manufacturer III are defective. Manufacturers I, II, and III supply 36%, 20%, and 44%, respectively, of the compact disks used by the company. What is the probability that a randomly selected label produced by the company will contain a defective compact disk?

An oil refinery is located 1 km north of the north bank of a straight river that is 3 km wide. A pipeline is to be constructed from the refinery to storage tanks located on the south bank of the river 5 km east of the refinery. The cost of laying pipe is $200,000/km over land to a point P on the north bank and $400,000/km under the river to the tanks. To minimize the cost of the pipeline, how far downriver from the refinery should the point P be located?

Suppose you have a cube of length s. The volume of that cube is V = s^3. Now let's suppose the dimensions of that cube (and hence its volume) depend on time. We are wondering about the relationship between the growth of the length versus the growth of the volume. Supposes(t) = t.Then s'(t) = t______________ and V'(t) = t ___________Next suppose V(t) = t. s'(t) = t______________ and V'(t) = t____________

HELP PLEASE!!! SHOW ALL YOU WORK PLEASE HELP HELP HELP PLEASEUse this information to answer the following questionsThe function a(x) = 210(1.12)x represents the number of ants in ant colony A x days after an experiment starts. The graph represents the number of ants in ant colony B during the same time period. (1st picture is colony B)How many ants in colony A per day, remember colony A is the function (2nd picture)During week 0, how many more ants are there in ant colony A than in ant colony B?Find the growth rate of ant colony A.Find the growth rate of ant colony B.Use 1-2 complete sentences to compare the growth rate of ant colony A with ant colony B.When does the daily number of ants in ant colony B exceed the daily number of ants in ant colony A? Explain your answer using 1-2 complete sentences.I will give even more points to the people who are correct and fast, Please help

Complete the function, h(t), which models Amare's height above the ground, in meters, as a function of time, t, in minutes. Assume he enters the ride at the low point when t = 0. h(t) = · sin( t + ) +

the ordered pairs below represent a relation between x and y. (-3,0), (-2,4), (-1,8), (0,12), (1,16), (2,20)could this set of ordered pairs have been generated by a linear function?A. No, because the distance between consecutive x-value is different than the distance between consecutive x-values.B. Yes, because the relative difference between y-values and x-values is the same no matter which pairs of (x, y) values you use to calculate it.C. No, because the y-values decrease and then increaseD. Yes, because the distance between consecutive x-values is constant.
