Answer:
1:3
Step-by-step explanation:
To find the probability of selecting a certain type of item from a collection, simply divide the number of items of that type by the total number of items.
There are 3 + 2 + 1 = 6 marbles in total. There are 2 yellow marbles, so the probability of choosing a yellow marble on the first draw is 2/6. This can be further simplified to 1:3.
It's B, remember when you have _ ( referring to =) you have straight line, but when it's just < or > you have dotted line

Answer:
2 containers should be used
As the system improves, neither more or fewer containers be required
Step-by-step explanation:
According to the given data we have the following:
D=83 pieces per hour.
T=80 minutes=1.33 hour
X=0.18
C=53
In order to calculate how many containers should be used we would have to use the following formula:
Number of containers=<u>DT(1+X)</u>
C
Number of containers=<u>(83)(1.33)(1+0.18)</u>
53
Number of containers=2.45=2
2 containers should be used.
As the system improves, neither more or fewer containers be required
