Hey there...
Critical path analysis is a technique that identifies the activities necessary to complete a task, including identifying the time necessary to complete each activity and the relationships between the activities.
I couldn't get an example for it but here are the steps:
1. Divide the project into tasks
2. Estimate tasks
3. Create the network diagram
4. Draw initial Gantt (bar) chart
5. Perform resource levelling
6. Compress the schedule (if necessary).

Hope it helps...

Answer:

Step-by-step explanation:

Put x = -13 to the equation -3x + 9y = 57

(-3)(-13) + 9y = 57

39 + 9y = 57 subtract 39 from both sides

9y = 18 divide both sides by 9

y = 2

A standard deck of cards has 52 cards divided into 4 suits, each of which has 13 cards. Two of the suits ($\heartsuit$ and $\dia

Gnoma [55]

Answer:

The number of ways to select 2 cards from 52 cards without replacement is 1326.

The number of ways to select 2 cards from 52 cards in case the order is important is 2652.

Step-by-step explanation:

Combinations is a mathematical procedure to compute the number of ways in which k items can be selected from n different items without replacement and irrespective of the order.

${n\choose k}=\frac{n!}{k!(n-k)!}$

Permutation is a mathematical procedure to determine the number of arrangements of k items from n different items respective of the order of arrangement.

$^{n}P_{k}=\frac{n!}{(n-k)!}$

In this case we need to select two different cards from a pack of 52 cards.

Two cards are selected without replacement:

Compute the number of ways to select 2 cards from 52 cards without replacement as follows:

${n\choose k}=\frac{n!}{k!(n-k)!}$

${52\choose 2}=\frac{52!}{2!(52-2)!}$

$=\frac{52\times 51\times 50!}{2!\times50!}\\=1326$

Thus, the number of ways to select 2 cards from 52 cards without replacement is 1326.

Two cards are selected and the order matters.

Compute the number of ways to select 2 cards from 52 cards in case the order is important as follows:

$^{n}P_{k}=\frac{n!}{(n-k)!}$

$^{52}P_{2}=\frac{52!}{(52-2)!}$

$=\frac{52\times 51\times 52!}{50!}$

$=52\times 51\\=2652$

Thus, the number of ways to select 2 cards from 52 cards in case the order is important is 2652.

find the volume of a cylinder with a base area of 25 pi in^2 And height equal to the radius. Give your answer both in terms of p

telo118 [61]

The base of the cylinder is a circle in which the area is calculated through the equation,
A = πr²
We are given that area is 25π in². From this and the equation above, the value of r is equal to 5 in. Using this calculated value as the height, the volume of the cylinder is,
V = Bh
where B is area of the base and h is height.
V = (25π in²)(5 in) = 125π in³
or also equal to,
V = 392.7 in

8t + 5 = 6t + 1 a 2 b -2 c 7

Maksim231197 [3]

Answer:b -2

Step-by-step explanation:

8t + 5 = 6t + 1 subtract 1 from both sides

8t + 4 = 6t subtract 8t from both sides

4 = -2t divide -2 from both sides

-2 = t

Have a nice day :)
