Question
The formula below is often used by project managers to compute E, the estimated time to complete a job, where O is the shortest completion time, P is the longest completion time, and M is the most likely completion time.
Which of the following correctly gives P in terms of E, O, and M?
- P = 6E - O - 4M
- P = - 6E + O + 4M
Hint:
The problem can be solved by doing some algebraic manipulations.
:
The correct answer is: P = 6E - O - 4M
Step 1 of 2:
The formula is given by,
⇒ 6E = O + 4M + P
⇒ P = 6E – O - 4M
The above formula gives P in terms of E, O and M.
Final Answer:
The right option is— A) P = 6E – O - 4M.

Lourdes plans to jog at least 1.5 miles . Write and solve an inequality to find X, the number of hours Lourdes will have to jog.
A distance is generally the amount of space or length that separates two people, objects, or situations. For example, four meters separate two streetlight poles, for instance, as a distance measure.
Where Distance = time × speed
Example: We kept a safe distance between two objects. At the same time, we notice a new space between object one and object 2. Although once close, there was a significant gap between the objects. However, wishes to distance themself from the object's former boss.

Solve inequality : 3x-2>4-3x and then graph the solution.
Note:
When we have an inequality with the symbols< or > , we use dotted lines to graph them. This is because we do not include the end point of the inequality.
