Answer:
(a) c = 40h + p
(b) $285
Step-by-step explanation:
(a)
Total Cost = (Cost per hour x Number of Hours) + Total Cost of Parts
c = 40h + p
(b)
For this case, p = $165 and h = 3:
c = 40*3 + 165 = $285
Answer:
The critical value is
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 8 - 1 = 7
80% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 7 degrees of freedom(y-axis) and a confidence level of . So we have T = 1.415.
The critical value is
Usando proporciones, hay que los $12,000 restantes deben ser investidos a una tasa de 11%.
<h3>¿Qué es una proporción?</h3>
Una proporción es una fracción de la cantidad total.
De las dos primeras inversiones, el ingreso es dado por:
0.08 x 15000 = $1,200.
0.09 x 22000 = $1,980
T = 1200 + 1980 = $3,180
Por la tercera inversión, busca-se un retorno de 4500 - 3180 = $1,320.
De esa forma, la tasa x es la seguiente:
12000x = 1320
x = 1320/12000
x = 0.11.
Los $12,000 restantes deben ser investidos a una tasa de 11%.
