g100num [7]

Answer:

the answer is below

Step-by-step explanation:

We have the total number of possible samples = 4 * 4 = 16 (As 4 choices for each value)

in addition we have to as all sample occur with equal probability, probability of each sample = 1/16, below is samling distribution of mean

x1 x2 probabilityP(x1,x2) sample mean

190 190    1/16                 190

190 100    1/16                 145

190 272    1/16                 231

190 74    1/16                 132

100 190    1/16                 145

100 100    1/16                 100

100 272    1/16                 186

100 74    1/16                        87

272 190    1/16                 231

272 100    1/16                 186

272 272    1/16                 272

272 74    1/16                 173

74 190    1/16                 132

74 100    1/16                 87

74 272    1/16                 173

74 74    1/16                 74

Summarizing above with adding duplicate values

sample mean   probability

       74              1/16

      87               1/8

    100                1/16

    132                1/8

    145                1/8

    173                1/8

   186                1/8

   190               1/16

    231               1/8

Un vendedor de celulaes tiene una meta diaria de venta si al momento lleva el Q.2,000.00 de la meta que equivale el 20%
astra-53 [7]

Answer:

Sales goal, S = Q. 10,000

Step-by-step explanation:

  • Let the daily sales goal be S.

<u>Given the following data;</u>

  • Amount sold = Q. 2,000.00
  • Percentage of the sales goal = 20%

To find his daily sales goal;

\frac {20}{100} * S = 2000

0.2 * S = 2000

Dividing both sides by 0.2, we have;

S = \frac {2000}{0.2}

<em>Sales goal, S = Q. 10,000</em>
