The probability that no more than 4 vehicles will change lanes is 50.71%.

Since the probability that a vehicle will change lanes while making a turn is 55%, supposing a random sample of 7 vehicles are observed making turns at a busy intersection, to find the probability that no more than 4 vehicles will change lanes while making the turn, the following calculation must be performed:

  • ((0.55 x 4) + (0.45 x 3)) / 7 = X
  • 0.5071 = X

Therefore, the probability that no more than 4 vehicles will change lanes is 50.71%.

Hello.

One jug contains

650 millilitres of water.

The other jug contains

300 millilitres of oil.

In order to find how much more water there is than oil, we need to take the amount of oil and subtract it from the amount of water:

\mathrm{650-300}

\mathrm{350}

Therefore, there are 350 more millilitres of water than oil.

I hope it helps.

Have a nice day.

Enter a positive value for k that makes this statement true 20 times k is less than 20 but greater than o
leonid [27]

Answer:

Step-by-step explanation:

If we're asked to use any positive value. It means we could have a wide variety of answer. A positive value of k that makes the equation 20k to be less than 20, yet greater than zero has to be any decimal value or a fraction, if you so wish.

As an example, if k is 0.5. Then we have

20k = 20 * 0.5 = 10, which is less than 20 and greater than zero

Again, if k is 0.9. Then we have

20k = 20 * 0.9 = 18, which is less than 20 and greater than zero.

So, you use any decimal number greater than 0, yet less than 1
