The manager of a gas station has observed that the times required by drivers to fill their car's tank and pay are quite variable
lesantik [10]

Answer:

0.4353 = 43.53%

Step-by-step explanation:

The times are exponentially distributed, so let's call n the mean, and x the time of transaction. The times of the transaction occurs in a certain time is:

e^{-x/n}

So, the probability that a car complete the transaction in less than 4 minutes, is 1 less the times it does it at 4 minutes:

P = 1 - e^{-4/7}

P = 0.4353

P = 43.53%

Mnenie [13.5K]

Answer:

your line goes through both (0,6) and (12,0)

Step-by-step explanation:

Ok so you are describing some lines you see I think:

I see some of these as points you mentioned:

(0,6)  ,  (0,-6)  , (6,0)

So let's see which of these work:

(0,6)?

2(0)+4(6)=24

        24=24

(0,6) does work!

The other point you have listed with (0,6) is (12,0).

Let's try (12,0)

2(12)+4(0)=24

24+0=24

24=24

(12,0) works!

So your line goes through both (0,6) and (12,0)

Answer:

32768 ways

Step-by-step explanation:

Because it is a selection with replacement; each selection is as follows:

First = 8\ marbles

Second = 8\ marbles

Third= 8\ marbles

Fourth = 8\ marbles

Fifth = 8\ marbles

Total number of ways is then calculated as:

Total = 8 * 8 * 8 * 8 * 8

Total = 32768
