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
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;

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

P(X< 10) = 0.632
The probability that the next on-the-job injury will occur within 20 days:

P(X< 5) = 0.393
The probability that the next on-the-job injury will occur within 1 days:

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

Answer:
24
Step-by-step explanation:
find 40% of 40 and then subtract the result from 40
(1, 9) and (11,1)
slope
= (9 - 1)/(1 - 11)
= 8 /-10
= -4/5
= - 0.8
answer
slope = - 0.8
