Square and quadrilateral!
Selections B and D both appear to be appropriate.
B) (x+8)² + (y+5)² = 13
D) (x+8)² + (y+5)² = 13
_____
The center is at the midpoint of the diameter, ((-10-6)/2, (-8-2)/2) = (-8, -5). For center (h, k) and radius r, the equation is
(x -h)² +(y -k)² = r²
(x -(-8))² +(y -(-5))² = (√13)²
(x+8)² + (y+5)² = 13
Answer:
153 times
Step-by-step explanation:
We have to flip the coin in order to obtain a 95.8% confidence interval of width of at most .14
Width = 0.14
ME =
ME =
ME =
use p = 0.5
z at 95.8% is 1.727(using calculator)
So, Option B is true
Hence we have to flip 153 times the coin in order to obtain a 95.8% confidence interval of width of at most .14 for the probability of flipping a head
Answer: 27 players will be notified during the third round of calls.
Step-by-step explanation:
In case the game is canceled, the coach calls three players. This means that if each of these three players call three more players, the number of players that will be notified during second round of call would be
3 × 3 = 9 players.
If each of these nine players call three more players, the number of players that will be notified during third round of call would be
9 × 3 = 27 players.
The total number of players that would have been notified is
3 + 9 + 27 = 39 players
