Answer:
(x - [-1])² + (y - [-1])² = [13]
Step-by-step explanation:
If P and Q are the end-points of the diameter PQ, midpoint of the segment PQ will be the center of the circle. (Definition of the center of a circle)
Midpoint of a segment having extreme ends and
Coordinates of the center =
Since, extreme ends of the diameter are P(-4, -3) and Q(2, 1)
Center of the circle =
= (-1, -1)
Radius of the circle = Distance between the center and Q,
Since distance between the two points and is,
d =
Radius of the circle =
=
=
Equation of the circle will be,
(x - h)² + (y - k)² = r²
Where (h, k) is the center and 'r' is the radius of the circle,
(x - [-1])² + (y - [-1])² = [13]
Answer:
Step-by-step explanation:
Subtract equation 2 from equation 1
.7x+y-(-1.5x+y)=340-320
.7x+y+1.5x-y=20
2.2x=20
x=100/11, then use this in either original equation to find y.
.7(100/11)+y=340
y=3670/11, so the balance point is
(100/11, 3670/11)
There are 24 hours in a day, so if it chimes twice in an hour it will chime 24*2 or 48 times a day. There are 7 days in a week, so it will chime 48*7 or 336 times.
Answer:
Less than or equal to 35 minutes will be needed
Step-by-step explanation:
Given that:
1 lap requires = 7 minutes
So,
5 laps will require <= 7 * 5 = 35 minutes almost
So the minutes taken will be less than or equal to 35 as the word almost is used with (5) laps.

The probability that a person is male if he is in jail, P(m/j), is high (far above 50%), since the given shows that there are more than 600,000 men while less than 100,000 women in jail. On the other hand, the probability that a person is in jail if he is a male, P(j/m), is fairly low, since far less than 50% of males are in jail. Therefore, these are likely to be different.
