The following data set shows the total number of people entering an exhibit per day: 163, 157, 166, 159, 160, 184, 162, 175, 177
, 164, 171, 170, 173, 176, 173, 178, 158, 163, 164, 169, 171, 160, 165, 182 Which intervals for the data values would be most appropriate for a frequency table?
Standard form of a circle" (x-h)²+(y-k)²=r², (h,k) being the center, r being the radius. in this case, h=-2, k=6, (x+2)²+(y-6)²=r² use the point (-2,10) to find r: (-2+2)²+(10-6)²=r², r=4 so the equation of the circle is: (x+2)²+(y-6)²=4²
