Answer:

<em>The approximate probability that a random vehicle is a passenger car is 74.67%</em>

Step-by-step explanation:

<u>Probability</u>

The traffic engineer records 112 passenger cars, 18 light trucks, and 20 heavy trucks. The total of vehicles recorded is n=112+18+20 = 150.

We are required to find the probability that a randomly selected vehicle crossing the bridge is a passenger car. There are 112 passenger cars, thus the probability is:

\displaystyle p=\frac{112}{150}

p = 0.7467

p = 74.67%

The approximate probability that a random vehicle is a passenger car is 74.67%

Laura owes $4759 on a credit card with a 20.9% interest rate compounded monthly. What is the monthly payment she should make in
Juliette [100K]
This can be calculated using the formula:
P = L((r/n)*(1 + r/n)^(n*t))/((1 + r/n)^(n*t) - 1)
Where:
L = 4759
r = 0.209
n = 12
t = 3
So plugging in our data:P = 4759((0.209/12)*(1 + 0.209/12)^(12*3))/((1 + 0.209/12)^(12*3) - 1)
Which will give us the amount of: $179.05 is the monthly repayments.

How do you subtract 4 4/9 - 2 7/9=
Daniel [21]
You would need to turn 4 4/9 and 2 7/9 into mix numbers. This would leave you with 50/9 - 25/9. Since the denominators are the same  you just need to subtract the numerators 50 - 25 = 25. So the answer is 25/9
