Answer:

The answer is letter A.

Explanation:

Less than or equal to 0.1

Because:

Average proportion (P-bar)= 0.024

Observations (n)= 75

sd =√(P-bar)(1-(P-bar)/n

sd =√(0.024)(1-0.024)/75

sd= √(0.024)(0.976)/75

sd= √(0.023424)/75

sd= 0.01767

sd ≤ 0.1

With an activity flexible budget, a budget variance is calculated a.based on a flexible budget based on various activity drivers
Vadim26 [7]

Answer:

C. 1. Identify the actual quantity of output. 2. Calculate the flexible budget for revenues based on budgeted selling price and actual quantity of output. 3. Calculate the flexible budget for costs based on budgeted variable cost per​ output, actual quantity of​ output, and actual fixed costs.

Explanation:

Any budget starts by determining our current output level.

To calculate the sales budget we must estimate our total revenue using our current output level and the estimated selling price for the next period. If we are certain that our output level will increase or decrease significantly over the next period, we can use the estimated output level instead of the current output level.

To calculate the costs budget we must estimate the variable costs per unit times the current output level (variable costs budget) and then we add the estimated fixed costs, which are not necessarily our current fixed costs.

Suppose the​ risk-free return is 6.5 % and the market portfolio has an expected return of 10.3 % and a standard deviation of 16
CaHeK987 [17]

Answer:

= 7.678%

Explanation:

Data provided

Risk free rate = 6.5%

Beta = 0.31

Marker return rate = 10.3%

Risk free rate = 6.5%

The computation of expected return is shown below:-

Expected return = Risk free rate + Beta × (Marker return rate - Risk free rate)

= 6.5% + 0.31 × (10.3% - 6.5%)

= 6.5% + 0.31 × (3.8%)

= 6.5% + 1.178%

= 7.678%
