You begin the week with 20 units of milk. You purchase 40 units. Your ending inventory for the week is 30 units. How many units
Musya8 [376]

Answer:

30 units.  

Step-by-step explanation:

Let x be number of milk units sold.

It has been given that You begin the week with 20 units of milk. You purchase 40 units. Therefore, total units of milk will be 20+40=60 units.

It has been given that your ending inventory for the week is 30 units, which means after selling x units from 60 units you are left with 30 units.

We can set this information in an equation as:

60-x=30

-x=30-60

-x=-30

x=30

Therefore, you have sold 30 units.

A stockbroker has kept a daily record of the value of a particular stock over the years and finds that prices of the stock form
amid [387]

Answer:

$12.43

Step-by-step explanation:

Given :

Mean = $8.52

Standard deviation, = $2.38

Stock price which falls beyond 0.05 of the distribution is at the 95th percentile

The 95th percentile distribution has a Pvalue of 1.645 (standard normal table)

We obtain the value of x, with z = 1.645

Using the Zscore relation :

Zscore = (score - mean) / standard deviation

1.645 = (score - 8.52) / 2.38

Cross multiply :

1.645 * 2.38 = score - 8.52

3.9151 = score - 8.52

Score = 8.52 + 3.9151

Score = $12.4351

Stock price beyond 0.05 is $12.43
