An office remodeling job takes 5 & 1/2 days to complete. Before working
Oksana_A [137]

Answer: The percent of the estimated time is the actual time is about 14%.

Step-by-step explanation:

As per given,

Actual time of completing the job = 5\dfrac{1}{2}\text{ days}=\dfrac{11}{2}\text{ days}

Estimated time for completing the job = 4\dfrac{3}{4}\ \text{days}=\dfrac{19}{4}\ \text{days}

The percentage error is given by:-

\%\text{ error}= \dfrac{|\text{Estimated-Actual}|}{\text{Actual}}\times100

=\dfrac{|\dfrac{19}{4}-\dfrac{11}{2}|}{\dfrac{11}{2}}\times100\\\\\\=\dfrac{|\dfrac{19-22}{4}|}{\dfrac{11}{2}}\times100\\\\\\=\dfrac{|\dfrac{-3}{4}|}{\dfrac{11}{2}}\times100\\\\\\=\dfrac{\dfrac{3}{4}}{\dfrac{11}{2}}\times100\\\\\\=\dfrac{3\times2}{11\times4}\times100\\\\\approx14\%

The percent of the estimated time is the actual time is about 14%.

In a data ,range is 17 and coefficient of range is 0.2 find the smallest term of the data.
anygoal [31]

Answer:

Step-by-step explanation:

Let largest value of data be L

and smallest value of data be S.

We are given that the range and coefficient of range of the data are 17 and 0.2 respectively.

Range formula is given by = Largest value - Smallest value

                   17  =   L - S

                  L = 17 + S ---------- [Equation 1]

Coefficient of range formula = (Largest - Smallest) ÷ (Largest + Smallest)

                                       0.2   =    l-s/l+s

                                      0.2 = 17/l+s

                 L + S = 17/0.2 = 85

So,    L + S = 85

       17 + S + S = 85   {using equation 1}

           2*S = 80

             S = 80/2 = 40

Putting value of S in equation 1, we get L = 20 + 40 = 60

Therefore,  Largest value, L = 60

               smallest value, S = 40
