A closed box has 6 faces.
There is 1 label on 1 face.
Subtract 1 from 6
6 - 1 = 5
5 faces is your answer
Hope this helps
First, write out all the prime factorisation of 30, 45, and 70.
30: 2*3*5
45: 3*3*5
70: 2*5*7
Then, find a number that all three numbers have in common; which is 5. So, 5 is the greatest common factors of 30, 45, and 70.
Y = X - 9
so 3X +2Y = 2
will be 3X +2×(X-9) = 2
3X + 2X -18 = 2
5X = 2 + 18
5X = 20
X = 4
Y = X - 9
Y = 4-9
Y = -5
the answer will be A) (4,-5)

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
