Center point is at: (-3+ X) (2+Y)
= change in range and domain
radius = (X-x)/2 or (Y-y)/2
Therefore: center is (1,-2) radius= 4
Equation: (x-1)^2+(y+2)^2=16
Answer:
(A) 0.11
(B) 0.0526
(C) Related
(D) 0.28
Step-by-step explanation:
The data provided is:
DC = event that a randomly selected driver is using a cell phone
TA = event that a randomly selected driver has a traffic accident
(A)
From the provided data:
P (DC) = 0.11
(B)
From the provided data:
P (TA) = 0.0526
(C)
To determine whether the events DC and TA are dependent, we need to show that:
The value of P (DC ∩ TA) is,
Now compute the value of P (DC) × P (TA) as follows:
So,
Thus, cell phone use while driving and traffic accidents are related.
(D)
The probability that the driver was distracted by a cell phone given that the driver has an accident is:
P (DC | TA) = 0.28
