Lilian's favorite magazine published 505050 issues last year, and each issue contained approximately 250250250 pages. She wants to take a cluster random sample of about 1{,}0001,0001, comma, 000 total pages to estimate what proportion of all pages contained an advertisement. a. Randomly select 4 issues, and examine every page in those issues
b. Examine 20 randomly selected pages from each of the 50 issues
c. Assign a unique number to each page, and use a computer to randomly select 1,000 of those numbers
d. Put the issues in a random order and examine every 10th page until 1,000 pages have been examined

160

step-by-step explanation:

idk

i hope i

step-by-step explanation:

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
