Answer:

(x + 7)² + (y - 8)² = 1

Step-by-step explanation:

(x - h)² + (y - k)² = r²

h = - 7, k = 8, r = 1

(x -(-7))² + (y - 8)² = 1²

(x + 7)² + (y - 8)² = 1

X = 29 and y = 101.

To find this, you need to set up an equation.

6x - 95 = 79. Once you solve this, x would equal 29.

Since 6x - 95 and y are on a straight line, they would have to equal 180. So you make another equation except you plug in 29 for x this time.

6(29) - 95 + y = 180. Once you solve this, y would equal 101.

\250 doctors from three countries in Europe meeting in a conference to decide whether to approve a new vaccine for the flu. Amon

Bezzdna [24]

Answer:

0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine

Step-by-step explanation:

(a) What is the probability that a randomly chosen doctor is in favor of the vaccine

75% of 115/250 = 0.46(German).

60% of 65/250 = 0.26(French).

65% of 70/250 = 0.28(Englishmen). So

$p = 0.75*0.46 + 0.6*0.26 + 0.65*0.28 = 0.683$

0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine

svetoff [14.1K]

Answer:

$\alpha = \frac{arc \: length}{radius} \\ arc \: length = \alpha \times radius \\ = 50 \times \frac{\pi}{180} \times 7 \\ arc \: length = 350 \times \frac{\pi}{180} \\ = 1.94 \times \pi \\ = 6.1metre \\ thank \: you$
