Answer:

<em>Most likely time, </em>according to PERT (Program evaluation and review technique).

Step-by-step explanation:

PERT is "a statistical tool used in <em>project management" (Program evaluation and review technique (2020), </em>in Wikipedia), and it is commonly used with CPM <em>(Critical Path Method)</em> to manage projects.

Inside PERT, there are different defined times to accomplished an activity in a project, that is:

  • An <em>optimistic time</em> or minimum time required to accomplished an activity, i.e., if everything goes better than normal, the activity is accomplished before expected.
  • A <em>pessimistic time, </em>a time quite the opposite to optimistic time.
  • A <em>most likely time</em>, or a time required to accomplished an activity if everything goes as expected or normally.
  • An <em>expected time</em>, an statistical estimation.

Considering the question, we have that the <em>time</em> when "the first module of the project could be completed":

  • "[...] in as few as 15 days"  is the <em>optimistic time</em>.
  • "[...] or could take as many as 25 days" is the <em>pessimistic time</em>.
  • "[...] but most likely will require 20 days" is the <em>most likely time</em>.

As a result, the <em>20-day estimate</em> is called the <em>most likely time</em> in the context of the PERT/CPM techniques.

Hello


Answer:

The correct answer is B

Step-by-step explanation:

You just use the Distribuatd property to solve

You multiply 10 to all the varibles inside the parthense

Becasued y is equal to 7 you would do 10x7=70

then 10x8=80

and 70+80=150

and the answer says the primeter is 150 when y=7

A local flower shop is selling $1 raffle tickets and is donating all proceeds to the children's hospital. They sold 5,500 ticket
xxMikexx [17]

Answer: The expected value of purchasing a raffle ticket would be $0.3449.

Step-by-step explanation:

Since we have given that

Number of tickets = 5500

Number of flower arrangements = 20

Number of gift certificates = 20

So, Probability that wining $70 at flower arrangement = \dfrac{20}{5500}=\dfrac{1}{275}

Probability that wining $25 at gift certificates = \dfrac{20}{5500}=\dfrac{1}{275}

So, Expected value of purchasing a raffle ticket would be

70\times \dfrac{1}{275}+25\times \dfrac{1}{275}\\\\=0.254+0.0909\\=\$0.3449

Hence, the expected value of purchasing a raffle ticket would be $0.3449.

Solve equation Y=9x-70 and y=2x-32
N76 [4]

Step-by-step explanation:

y = 9x - 70 ...1

y = 2x - 32 ...2

...1 - ...2

0 = 7x -38 ...3

7x - 38 = 0

7x = 38

x = 38/7
