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

Answer:
brainliest plzzz
Step-by-step explanation:
2x - y = 7 is in standard form, and if it were slope-intercept form that would help you. I got the y term by itself:
y = 2x - 7 slope-intercept form. You already know the slope of the perpendicular line is the *negative reciprocal* of the slope you have. So that's (-1/2). The perpendicular line is something like
y = -(1/2)x + b and if you substitute 8 for x and 5 for y you get 9 for b.
y = -(1/2)x + 9 is your perpendicular line. In slope-intercept form. To get back to standard form, start by getting rid of fractions. Multiply both sides by 2.
2y = -x + 18 then add x to both sides.
x + 2y = 18 done.
