Answer:
a. Yes. It is a probability density function because \sum f(x) =1
. b. probability MCC will obtain more than 30 new clients=P(40)+P(50)+P(60)= 0.20+0.35+0.20=0.75
c. probability MCC will obtain fewer than 20 new clients= P(10)= 0.05
d.
x	f(x)	x*f(x)	x*x*f(x)
10	0.05	0.5	5
20	0.1	2	40
30	0.1	3	90
40	0.2	8	320
50	0.35	17.5	875
60	0.2	12	720
1	43	2050
expected value = \sum xf(x) = 43
Variance = 2050-43^2= 201

Answer:
Cost of goods sold on April 25 is $13.80 and the inventory balance is $55.20
Explanation:
Data given:total unit
Cost of purchase with  data;
 Date                  Amount
 April 5                 $10
April 10                $12
April 15                $14
April 20                 $16
April 22                 $17
Total cost             69    
Average cost = total cost /total quantity
                        = 69/5
                        =13.8
The cost of the ending inventory is given on the balance sheet below
Date      Purchases              Cost of            Inventory Bal.   Avg Cost
                                             goods sold
April 5   $10* 1 unit= $10                -                        $10               10/1 = $10
April  10  $12* 1 unit=$12               -               10+ 12 = 22            22/2 = 11
April  15   $14* 1 unit=$14                  -           22+14 =36              36/3 = 12
April 20   $16* 1 unit= $16                  -          36 +16 =52            52/4 = 13
April 22    $17* 1 unit = $17                 -          52+17 =69            69/5 = 13.8
 
April 25             -           1 unit*13.8 = 13.80      69 - 13.8 = 55.20
