Answer: 18 units long
Step-by-step explanation:
In the diagram, it looks like line segment AW is 6 units long and WB is 12 units long. Because of parts-whole postulate (the whole is equal to the sum of its parts), you can add AW and WB's lengths together. 6 + 12 = 18, so the length of line segment AB is 18 units long.
To find out time interval δt we need to substract initial time from the final time. In this question first number in the coordinates representes time:
δt=50 - 0
δt= 50s
TIme interval is 50s.
27, you need to simplify both sides of the equation to get x on one side.
In this case, the complement would be selecting a number less than or equal to 7; the probability of this occurring is
