Answer:
24.7215
Explanation:
Given;
Discount = 50%
Regular price, p = $8
cost of cake, c = $5
salvage value, s = 50% of $8 = $4
Mean = 20
Standard deviation, σ = 7
Now,
Underage cost, Cu = p - c
= $8 - $5
= $3
Overage cost, Co = c - s
= $5 - $4
= $1
P ≤ 
P ≤ 
P ≤ 0.75
The Z value for the probability 0.75 is 0.6745
The optimal stocking level = Mean + ( z × σ )
= 20 + 0.6745 × 7
= 24.7215
Answer:
$37,600 favorable
Explanation:
Variable overhead spending variance can be computed as;
= (Actual hours worked × Actual variable overhead rate) - ( Actual hours worked - Standard variable overhead rate)
= ( 18,800 hours × $77,700/12,000) - (18,800 hours × $4.5)
= [(18,800 × $6.5) - (18,800 × $4.5)]
= $122,200 - $84,600
= $37,600 favorable
Answer:
0.67
Explanation:
Beta measures the systemic risk of a portfolio
The portfolio's beta can be determined by adding together the weighted beta of each stock in the portfolio
weighed beta of a stock = percentage of the stock in the portfolio x beta of the stock
total number of stocks in the portfolio 400 + 290 + 700 = 1390
(400 / 1390 x 0.6) + (290 / 1390 x 1.2) + (700 / 1390 x 0.5) =
0.17 + 0.25 + 0.25 = 0.67
