A company has 8 mechanics and 6 electricians. If an employee is selected at random, what is the probability that they are an ele

Andre45 [30]

Answer:

$Probability = \frac{3}{7}$

Step-by-step explanation:

Given

Electrician = 6

Mechanic = 8

Required

Determine the probability of selecting an electrician

First, we need the total number of employees;

$Total = n(Electrician) + n(Mechanic)$

$Total = 6 + 8$

$Total = 14$

Next, is to determine the required probability using the following formula;

$Probability = \frac{n(Electrician)}{Total}$

$Probability = \frac{6}{14}$

Divide numerator and denominator by 2

$Probability = \frac{3}{7}$

Hence, the probability of selecting an electrician is 3/7

Answer:

movie: $3.75
video game: $5.75

Step-by-step explanation:

Two equations in two unknowns can be written:

3m +5v = 40

9m +7v = 74

These can be solved a variety of ways. One of them is using Cramer's rule. It tells you the solution to

ax +by = c
dx +ey = f

is given by ...

∆ = bd -ea
x = (bf -ec)/∆
y = (cd -fa)/∆

For the numbers above,

∆ = 5·9 -7·3 = 24
m = (5·74 -7·40)/24 = 90/24 = 3.75
v = (40·9 -74·3)/24 = 138/24 = 5.75

The rental cost for each movie is $3.75; for each video game, it is $5.75.
