If the studies are inconsistent, it means that at least some of the age group from the first study will not be included in the second study, or some of the age group from the second study will not be in the first study. Therefore, to determine if the two studies are inconsistent in their description of generation A we must compare the age groups from the two studies to see if either one includes people not included in the other study. In other words, we need to determine if the age ranges match up exactly when the year of the study is taken in to consideration. In the first study from 2007, generation A is defined to be people ages 15–26. Three years later, in 2010, the second study was published and defined generation A to be people ages ages 18–29.First we examine the low end of the age ranges. We note that someone who was 19 years old in 2007 would be years old in 2010. Now we examine the high end of the age ranges. We note that someone who was 30 years old in 2007 would be years old in 2010. The low and high ends of the age ranges for the two studies when the year the studies were published is taken in to consideration. Therefore, the studies inconsistent.

answer: about 22.67

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

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:

something over 10 so ? /10
