Researchers were interested in comparing students at private universities and students at public universities with respect to how much time they spent working in a typical week. They e-mailed a survey to 1000 students enrolled at a particular private university and to 2000 students enrolled at a particular public university. Data from the 200 private university students who responded to the survey and the 900 public university students who responded to the survey were used to see if there was a significant difference in the mean number of hours worked in a typical week. Which of the following does NOT limit the researchers’ ability to generalize to the two populations of interest?

x=12 units bd= 10 units

step-by-step explanation:

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'

answer: do we write it

step-by-step explanation:

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
