Esther wants to know if the number of words on a page in her language arts book is generally more than the number of words on a page in her social studies book. she takes a random sample of 25 pages in each book and then calculates the mean, median, and mean absolute deviation for the 25 samples of each book. book mean median mean absolute deviation language arts 78.5 60 14.2 social studies 68.7 65 9.8 she claims that because the mean number of words on each page of the language arts book is greater than the mean number of words on each page of the social studies book, the language arts book has more words per page. based on the data, is this a valid inference? yes, because there is a lot of variability in the language arts book data no, because there is a lot of variability in the language arts book data yes, because the mean is larger in the language arts book no, because the mean is larger in the social studies book

So the correct answer is "No, because there is a lot of variability in the language arts book data."

Step-by-step explanation: I'm doing this test right now on FLVS and i used this answer for help and i got a 100 so this answer is VERY correct.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

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
