It will take them 5 Hours to charge the same. The rental charge will be 510.
I did a manual computation per company: My computation is entirely based on trial and error.
Red Bus Co. has a fixed rental rate of 150 and additional rental of 72 per hour while Blue Bus Co. has a fixed rental rate of 240 and additional rental of 54 per hour. Both fixed rental rate are one time charges only and total rental will vary on the number of hours spent in using both vehicles.
Let's start with the Red Bus Co. I will be posting the charges per hour and its running balance. The running balance is the sum.
Fixed Rate 150 Running Balance: 150 => 150 + 0
Hr 1 72 222 => 150 + 72
Hr 2 72 294 => 222 + 72
Hr 3 72 366 => 294 + 72
Hr 4 72 438 => 366 + 72
Hr 5 72 510 => 438 + 72
I'll do the same process with Blue Bus Co.
Fixed Rate 240 Running Balanc: 240 => 240 + 0
Hr 1 54 294 => 240 + 54
Hr 2 54 348 => 294 + 54
Hr 3 54 402 => 348 + 54
Hr 4 54 456 => 402 + 54
Hr 5 54 510 => 456 + 54
Its C.
Negative x Negative is positive, so its not A or D.
Positive x Positive is Positive, so its not B either.
C is your option because Positive x Negative is Negative, and vice verca.
Answer: Option 'a' is correct.
Step-by-step explanation:
Since we have given that
Probability of owned a sedan = 39%
Probability of owned a van = 33%
Probability of owned a sports car = 7%
n = 3
We need to find the probability that all three randomly selected households own a van.
So, Probability of getting all 3 own a van is given by
Hence, Option 'a' is correct.
