Answer:
Step-by-step explanation:
14.
by pythagoras,s theorem
15.
first perpendicular=y(say)
and second perpendicular=z (say)
y²=9²+7²=81+49=130
z²=y²+5²=130+25=155
x²=z²+4²=155+16=171
x=√(171)
Answer:
0
Step-by-step explanation:
(x – y) – (x – y)
Distribute the minus sing
x-y-x+y
Combine like terms
x-x-y+y
0
Answer:
3 days
Step-by-step explanation:
This can be seen under Schedule management (Initiating)
Project float is simply the difference between the completion period externally imposed and the estimated time duration of the project (usually this is equal to the critical path length). The difference in this case is 0 because
Externally imposed project date = 75 days
Estimated duration of project = 75 days
Hence, a difference in these will be 0
However, a standard deviation of 3 days was giving (This implies that there is a +/- 3 days in the critical path from the estimated project duration)
.
Hence the maximum float in this case will be 0 + 3 = 3 days
check the picture below. You can pretty much just count the units from the grid.
No. If you subtract a negative from a positive number its equivalent to adding the inverse of that negative number. If you add a negative to a positive number It is equivalent to subtracting from that positive number.
