Answer:
(x-4)*2 + (y-2)*2 = 25
Step-by-step explanation:
(x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.
h = 4
k = 2
r = 5
sub in all this info:
(x-4)*2 + (y-2)*2 = 25
Answer:
30%
Step-by-step explanation:
Total number of people registered for the two days seminar = 1000
90% of those registered attended on the first day
This means (90/100)1000 = 900 people attended the seminar on the first day.
That means 100(1000 -900) registered people did not attend the seminar on the first day
80% of those registered attended on the second day
This means (80/100)1000 = 800 people attended the seminar on the second day.
That means 200 (1000 -800) registered people did not attend the seminar on the second day
The percent of those registered did not attend the seminar on either day = 100 + 200 = 300
= 30%
Total = Group A + Group B - (both + neither)
1000 = 900 + 800 - (B + N)
The two unknown variables (both and neither)
