A vet wants to determine which of two brands of flea treatment is best for the cats in the shelter. Before using one of the few treatments on all the cats the vet decides to conduct experiment Individual cats. Which of the following two plans for randomly assigning the treatments should the vet use? Explain. Plan A: Choose the 16 cats that are most riddled with fleas. Apply Brand M to al 16 of those cats. Apply Brand N to the remaining 16 cats
Plan B: Choose 16 of the 32 cats at random. Apply Brand M to those 16 cats and Brand N to the remaining 16 cats
a. Plans A and B are equivalent because they both follow experimental design.
b. Plans A and B are both poorly designed because there are not entugh cats to test
c. Plan A, because the cats that have the most heas need the free treatment the most and should be treated first
d. Plan B, because the sample of cats is randomly chosen
e. The plans cannot be evaluated from the information given

when functions are first introduced, you will probably have some simplistic "functions" and relations to deal with, usually being just sets of points. these won't be terribly useful or interesting functions and relations, but your text wants you to get the idea of what the domain and range of a function are. small sets of points are generally the simplest sorts of relations, so your book starts with those.

step-by-step explanation:

state the domain and range of the following relation. is the relation a function?

{(2, –3), (4, 6), (3, –1), (6, 6), (2, 3)}

the above list of points, being a relationship between certain x's and certain y's, is a relation. the domain is all the x-values, and the range is all the y-values. to give the domain and the range, i just list the values without duplication:

domain: {2, 3, 4, 6}

range: {–3, –1, 3, 6}

(it is customary to list these values in numerical order, but it is not required. sets are called "unordered lists", so you can list the numbers in any order you feel like. just don't duplicate: technically, repetitions are okay in sets, but most instructors would count off for this.)

while the given set does indeed represent a relation (because x's and y's are being related to each other), the set they gave me contains two points with the same x-value: (2, –3) and (2, 3). since x = 2 gives me two possible destinations (that is, two possible y-values), then this relation is not a function.

note that all i had to do to check whether the relation was a function was to look for duplicate x-values. if you find any duplicate x-values, then the different y-values mean that you do not have a function. remember: for a relation to be a function, each x-value has to go to one, and only one, y-value.

state the domain and range of the following relation. is the relation a function?

{(–3, 5), (–2, 5), (–1, 5), (0, 5), (1, 5), (2, 5)}

i'll just list the x-values for the domain and the y-values for the range:
