Answer:
8 hours
Step-by-step explanation:
Job v starts at time 0 and completes at time 3.
Job w starts at time 1 and completes at time 4.
Job x starts at time 4 and completes at time 8.
Job y starts at time 8 and completes at time 10.
Job z starts at time 10 and completes at time 15.
The average completion time is (3 +4 +8 +10 +15)/5 = 8 . . . hours.
_____
<em>Comment on the schedule</em>
Jobs v and x are the only ones completed by the time due. The latest is 8 hours late. If they are scheduled in order of due time, jobs v, w, and y can be completed by the due time; the others will be 4 and 6 hours late.
Answer and explanation:
Please find attached answer and explanation
The all possible eight outcomes of boy or girl birth when a couple have three children is
(GBB) , (GBG), (GGB) , (GGG), (BBG), (BGB), (BGG), (BBB)
Where B represents boy and G represents Girl
The probability that having exactly 1 girl is
= Number of outcomes with one girl / Total numbers of outcomes
Now Number of outcomes with only one girl = GBB, BGB, BBG = 3
So the probability will be
The probability that having exactly 1 girl is = 3/8 = 0.375
The probability that when a couple has three children, there is exactly 1 girl is 0.375
<u><em>Answer:</em></u>
a. The point (4,9) appears in both tables
<u><em>Explanation:</em></u>
<u>Note:</u> This question can be solved without the need of the tables
<u>A solution of a system of equations</u> is defined as a point (or set of points) that satisfy both equations
<u>This means that,</u> this point should belong to all the equations in the system
Now, a table is used to show a set of points that belong to a certain line
This means that, all vales in the table belong to the line they represent
<u>Since the point (4,9) appears in both tables</u>, therefore, it belongs to both lines and, therefore, is a solution to the system of equations consisting of these two lines
Hope this helps :)
