Answer:
Step-by-step explanation:
Given a circle Q represented by the equation:
Comparing with the standard form of the equation of a circle center (h,k) of radius r:
We have:
We take the square root to obtain the radius, r of the circle.
Since segment KL is a diameter of circle Q; and
Diameter =Radius X 2
Therefore:
Let A represents the event that DVD has a video effect.
So,
P(A) = 1.5 %
Let B represents the event that DVD has a audio defect.
So,
P(B) = 0.8 %
A ∩ B represents that DVD has both audio and video defect.
So,
P(A∩B) = 0.4%
Part a)
A ∪ B represents that DVD has a video or audio defect.
P(A∪B) = P(A)+P(B)-P(A∩B) = 1.5 + 0.8 - 0.4 = 1.9%
Thus the probability that the DVD purchased by the customer has a video or audio defect is 1.9%.
Part b)
The complement of P(A∩B) will represent the probability that the DVD does not have video or audio defect.
So, the probability that DVD purchased by customer does not have video or audio defect is 1 - 0.4 = 0.96%
Answer:
2.44444....
Step-by-step explanation:
if 22lbs of flour = $9
then you can write the equation out as:
22 = 9
Divide both sides by 9 to get:
2.4444444..... = 9
$1 = 2.44 lbs of flour
First, we put the values of the given point into the general equation, giving:
0 = m * -1 + b .......(1)
Now plug in the given value of m into equation (1), giving:
0 = 2 + b ........(2)
Solving equation (2), we find that b = -2.
Now we can write the required equation as:
y = -2x - 2
