The heights of men in a particular country are normally distributed with a mean of 68 inches and a standard deviation of 3 inches. this means that the fraction of men with a height between a and b (with aless thanb) inches is given by the integral below. what percentage of american men are between 61 and 75 inches tall? use the method of your choice and, starting with one subinterval, increase the number of subintervals by 1 until you obtain successive approximations that differ by less than 10 superscript negative 3. use the last approximation as the answer.

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
