Neporo4naja [7]

Answer:

  about 0.0143 microfarads

Step-by-step explanation:

The effective capacitance of capacitors in series is the reciprocal of the sum of their reciprocals:

What is the variance for this activity? activity a m b t es ef ls lf 7 1 1.5 2 1.50 8 9.50 8 9.50
Lina20 [59]

The variance for this activity  is  mathematically given as

Var=0.026  

<h3>What is the variance for this activity?</h3>

A data set's variance may be seen as a measurement of the spread that exists between the individual integers. When evaluating the asset allocation of a portfolio, investors employ an expression known as the variance equation.

After careful consideration of the  table given in the question, we have that

Pessimistic time tp=2

optimistic time to=1

most likely time tm=1.5

Generally, the equation for variance is  mathematically given as

\sigma^2=\frac{tp-to}{6}^2

Therefore

\frac{2-1}{6}^2\\\\\sigma^2=1/6^2

Var=0.026  

In conclusion,  the variance for this activity

Var=0.026
