we know that

the total budget is $1,695------>  this amount represent the 100%

The total for electric, phone, and water is equal to

$176.62+$45+$16=$237.62

<u>Find the percentage</u>

=(237.62*100)/1,695

=14.02%

therefore

<u>the answer is</u>

14%

7. The length of time (in months after maintenance) until failure of a bank’s surveillance television equipment follows a Weibul
cupoosta [38]

Answer:

The frequency by which the equipment should receive periodic maintenance is   x= 13.59

Step-by-step explanation:

A Wellbull distribution is mathematically represented as

            f(x,\alpha, \beta  ) = \left \{ { {\frac{\alpha }{\beta^{\alpha } }x^{\alpha -1} e^{-[\frac{x}{\beta } ]^\alpha} \ \ \ \  \ \ \\ \\ , x \ge0} \atop {0 \ \ \ \ \ \ \ \  Otherwise }} \right.

Where x is the frequency that the equipment should receive periodic maintenance  

probability of a breakdown before the next scheduled maintenance is mathematically represented as

                 P(x) = \int\limits^x_0 {\frac{\alpha }{\beta^{\alpha } } x^{\alpha -1 } e^{-[\frac{x}{\beta } ]^{\alpha }} } \, dx

Substituting 2 for \alpha and 60 for \beta 0.05 for P(x)

               0.05 = \int\limits^x_0 {\frac{2}{60^2} x^{2-1} e^{-[\frac{x}{60}]^2  } \, dx

              0.05 = \frac{2}{3600}\int\limits^x_0 {xe^{[-\frac{x^2}{3600} ]}} \, dx

Let v = - \frac{x^2}{3600}

=>  dv = \frac{-xdx}{1800}

=>  -xdx = 1800\ dv

Multiply both sides by minus

=> xdx = -1800dv

Substituting this into the equation

          0.05 = \frac{2}{3600} \int\limits^x_0 {-1800 e^u} \, du

Integrating and substituting back for x

           0.05 = -\frac{1800}{1800} [e^{[-\frac{x^2}{3600} ]}]\left {{x} \atop {0}} \right.

    substituting for  the range of x and 0

          0.05 = -  [e^{-[\frac{x^2}{3600}]  } -1]

          0.05 = -e^{[-\frac{x^2}{3600} ]} +1

          0.05 -1 = -e^{-\frac{x^2}{3600} }

         -0.95 = -e^{[-\frac{x^2}{3600} ]}

         0.95 = e^{[-\frac{x^2}{3600} ]}

Taking ln of both sides

      -0.05129 = - \frac{x^2}{3600}

     making x the  subject of the formula

        x = \sqrt{0.05129 * 3600 }

           x= 13.59

X-y = 4
X-8 = 2
Work the 2nd equation out, you get x=10
10-y = 4
Y=6

So x=10 and y= 6
