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:
it will be 10.5 so he will take the bus
Step-by-step explanation:
Answer:
20 years
Step-by-step explanation:
<u>Continuous Compounding Formula</u>
where:
- A = Final amount
- P = Principal amount
- e = Euler's number (constant)
- r = annual interest rate (in decimal form)
- t = time (in years)
Given:
- A = $10,000
- P = $5,000
- r = 3.5% = 0.035
Substitute the given values into the formula and solve for t:
Therefore, it will take 20 years (to the nearest year) for the initial investment to double.
Answer: 7/10
Step-by-step explanation:
Substitute w for 10
10-3 / 10 = 7/10
