20 liters of mixture contain milk nad water in the ratio 5:3 of 4 liters of the mixture are replaced by 4 liters of milk find th
pantera1 [17]

Answer:

7:3

Step-by-step explanation:

5 + 3 = 8

The ratio is

5 milk : 3 water : 8 total

Milk is 5/8 of the total.

Water is 3/8 of the total.

The 20-liter mixture contains:

5/8 * 20 = 12.5 liters of milk, and

3/8 * 20 = 7.5 liters of water

4 liters of the mixture contain:

5/8 * 4 = 2.5 liters of milk, and

3/8 * 4 = 1.5 liter of water

When you remove 4 liters of the mixture from 20 liters of the mixture, you end up with

12.5 L - 2.5 L = 10 L milk, and

7.5 L - 1.5 L = 6 L water

Now you add 4 liters of milk. Now you have

10 L + 4 L = 14 L milk

6 L water

The new ratio of milk to water is 14:6 = 7:3

An on-the-job injury occurs once every 10 days on
ExtremeBDS [4]

The probability that the next on-the-job injury will occur within 10, 5, and 1 day are 0.632, 0.393, and 0.095

<h3>What is probability?</h3>

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We know the exponential distribution is given by;

\rm P(X < t)=1-e^{-\dfrac{1}{\mu}t}

The probability that the next on-the-job injury will occur within 10 days:

\rm P(X < 10)=1-e^{-\dfrac{1}{10}10}

P(X< 10) = 0.632

The probability that the next on-the-job injury will occur within 20 days:

\rm P(X < 5)=1-e^{-\dfrac{1}{10}5}

P(X< 5) = 0.393

The probability that the next on-the-job injury will occur within 1 days:

\rm P(X < 1)=1-e^{-\dfrac{1}{10}1}

P(X< 1) = 0.095

Thus, the probability that the next on-the-job injury will occur within 10, 5, and 1 day are 0.632, 0.393, and 0.095
