Answer:
The equation of circle is + = 52
Step-by-step explanation:
Given the endpoints of diameter of a circle: (-16,-16) and (-4,-8)
We know that the equation of circle is given by
+ =
where (x,y) is any point on the circle, (h,k) is center of the circle and r is radius of circle.
To find (h,k): the center is midpoint of diameter
Midpoint of diameter with end points (x1,y1) and (x2,y2) is given by
( , )
( , )
(-10, -12)
Hence (h,k) is (-10,-12)
Substituting values of (h.k) and (x.y) as (-10,-12) and (-4,-8) respectively in equation of circle, we get
+ =
= 52
Substituting values of (h.k) and , we get the equation of circle as
+ = 52
Hence the equation of circle is + = 52
Answer: (p/5) + 30
Step-by-step explanation:
We are dividing the parking amount they had to pay by the 5 friends since they are splitting the amount they pay. Then we are adding 30 because that is how much each friend is paying.
Answer:
What grade math is this??
Step-by-step explanation:
Answer: 0.34
Step-by-step explanation:
Given : The proportion of items in a shipment are known to be defective : p=0.08
Number of items selected = 5
By using binomial probability distribution formula, the probability of getting success in x trials is given by :-
Now, the probability that at least one defective item will be observed in this sample will be :-
Hence, the probability that at least one defective item will be observed in this sample is 0.34
