Answer: The precise answer is 2/3x + 17
Step-by-step explanation:
Assuming that every material in their respective categories has an equal likelihood of selection.
Categories:
(a) Wood types for cabinets: birch, maple, cherry.
Each wood type has a selection probability of 1/3.
(b) Finish types: transparent, semi-transparent.
Each finish type has a 1/2 chance of being selected.
(c) Knob types: bronze, steel, wood.
Each knob material carries a probability of 1/3.
The selection of materials for the cabinet, finish, and knobs is independent of one another.
Consequently,
Probability(birch wood AND bronze knob) = (1/3)*(1/3) = 1/9
Probability(wood knob) = 1/3
Probability(transparent stain) = 1/2
Probability(cherry wood AND semi-transparent stain) = (1/3)*(1/2) = 1/6
Al establecer un sistema de ecuaciones lineales, se determina que el total de obreros que contrató el ingeniero civil es 50.
Para descubrir cuántos obreros fueron contratados, se debe formular un sistema de ecuaciones lineales con dos ecuaciones y dos incógnitas, de la siguiente manera:
(1)
(2)
Donde:
M: representa la incógnita correspondiente al capital del ingeniero
x: simboliza la incógnita que denota el total de obreros
De la ecuación (1) podemos deducir:
(3)
Utilizando la ecuación (3) en la ecuación (2) podríamos calcular el valor de x (número de obreros):
El monto inicial del ingeniero, según la ec (3), sería:
Por lo que, el número de obreros contratados por el ingeniero es 50.

Answer:
0.93 minute
Step-by-step explanation:
During the first week:
Kim ran = 1 mile
Duration for this distance = 1 minute
In the second week:
The distance covered by Kim = 1 mile
The time taken by Kim = 7% less compared to the first week
= 1 min - 0.07 min = 0.93 minute
<pSo, she completed 1 mile in 0.93 minute this week.
