Answer: Callie and Gellen have equivalent heart rates.

Step-by-step explanation:

Hi, to solve this problem we have to calculate each beat per second of each individual.

So:

Aaron 166 times in 120 seconds: 166/120: 1.30 beat per second

Callie  88 times in 60 seconds: 88/60: 1.46 beat per second

Amma 48 times in 30 seconds: 48/30: 1.6 beat per second

Galen 22 times in 15 seconds: 22/15: 1.46 beat per second

Callie and Gellen have the same results.

So, Aaron and Gellen have equivalent heart rates.

Feel free to ask for more if it´s necessary or if you did not understand something

Aaron: 166 times in 120 seconds, or 83 times in 60 seconds
Callie; 88 times in 60 seconds
Emma: 48 times in 30 seconds, or 96 times in 60 seconds
Galen: 22 times in 15 seconds, or 88 times in 60 seconds

Callie's and Galen's heart rates are equivalent.

mauricio estimates that the first module of the project could be completed in as few as 15 days or could take as many as 25 days
4vir4ik [10]

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.

If machanical advantage of simple machine is 4, what dose it indicates?​
Savatey [412]

Answer:

Velocity ratio of simple machine is the ratio of distance travelled by effort to the distance travelled by load in the machine.Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 4 means that for example if you apply 100 N then your machine will multiply that force and generate 400 N.

beks73 [17]

Answer:

(mxt) miles

Step-by-step explanation:

speed = m \: miles \: per \:minute \\ time \:  = t \: minutes \\ speed =  \frac{distance}{time}  \\ m =  \frac{d}{t}  \\ m \times t \:  = d \\ d = (m \times t)miles

hope that this is helpful.
