These are the means and standard deviations for samples of building heights
in two different cities.

City A
Mean: 120 ft
Standard deviation: 20 ft

City B
Mean: 240 ft
Standard deviation: 12 ft

Select the two true statements.

A. City A's heights are more spread out than city B's heights.
B. City A's heights are less spread out than city B's heights.
c. City A has a lower average height than city B.
D. City A has a greater average height than city B.

600,000,000,000, or 6e14

step-by-step explanation:

one set of data has more variation than the other. hope this !

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
