Answer:
a) YTM = 9.8%
b) realized compound yield = 9.9%
Explanation:
a) PMT is 80
par value FV = 1000
coupon rate = 8%
current price PV = 953.1
years to maturity n = 3
Yield to maturity (YTM) is calculated as 
= 
= 9.8%
b) r2 = 10% = 100%+10% = 1.1
r3 = 12% = 100%+12% = 1.12
To find the realized compound yield, we first need the future value (FV) of the principal and reinvested coupons.
FV = ($80 * 1.10 * 1.12) + ($80 * 1.12) + $1080 = $1268.16
Let a be the rate at which the future value equals $1268.16.
953.1(1+y)³ = $1268.16
(1+y)³ = 1.33
1+y = 1.099
y = 0.099 = 9.9%
Answer:
a) 120 skiers daily
b) 6.25% rise in revenue
Explanation:
a) Assuming each skier stays for an average of 10 days, the daily turnover corresponds to 1/10 of the total skiers, which results in 1200/10 = 120 skiers daily.
__
b) For a duration of n days, the average expenditure for a skier is...
50 +(n-1)30 = 20 +30n
and the average daily spending calculates to...
(20 +30n)/n = (20/n) +30
Thus, for a 10-day visit, the average skiier's restaurant spending is...
20/10 +30 = 32.... each day
Similarly, for a stay of 5 days, the average skier's expense becomes...
20/5 +30 = 34.... each day
The anticipated change in restaurant revenue is...
(34 -32)/32 × 100% = 2/32 × 100% = 6.25%
Restaurant revenues are projected to increase by 6.25% from the previous year.
Answer:
Total hours worked = 17,550 hours
Explanation:
Labour hours efficiency variance = labour efficiency variance/standard labour cost per hour
The hourly standard labour cost = $24
= 1,200/24= 50 hours
Labour variance (in hours) = Actual labour hours - Standard hours for actual units produced
The standard labour hours allowed for the production of 875 cranes is:
= 20 × 875 = 17,500 hours
Let the actual hours be "y"
50 = y - 17500
y = 50 + 17500
y= 17,550 hours
Total hours worked = 17,550 hours
Answer:
Part a:
Show the probability density function for the waiting times at Kroger, assuming they are exponentially distributed.
Solution:
Probability density function f(x) = (1/ )*e-x/ = (1/26)*e-x/26 (result)
Part b:
Calculate the probability that a customer waits between 15 and 30 seconds.
Solution:
0.2462
Part c:
Determine the probability that a customer must wait longer than 2 minutes.
Solution:
0.0099
Explanation:
All calculations are included.
Respuesta:
La respuesta es 200%.
Explicación:
Supongamos que Toni produce x tartas de manzana en y horas.
Esto significa que el ritmo de producción es 
tartas por hora.
Trabajando con un asistente:
Toni incrementa su producción en un 60%, es decir, ahora hace x + 0.6x = 1.6x tartas.
Además, reduce su tiempo trabajando en un 20%, entonces trabaja y - 0.2y = 0.8y horas.
Por lo tanto, la tasa de producción con ayuda es 1.6x / 0.8y = 
.
Al simplificar, obtenemos un aumento del 200% en la producción por hora.
