Answer:
The Probability = 0.20
Step-by-step explanation:
From the question stated, the first step to take is to find probability that an employee selected at random will need either eyeglasses or major dental work
Solution
Given
Now,
The exams showed tha the number of employees needed eyeglasses = 8%
Employees that needed major dental work = 15%
Employees that needed both eyeglasses and major dental work =3%
Thus,
The P(needed eyeglasses ) = 8% = 0.08
P(major dental work) = 15% = 0.15
P(eye glasses and major dental work) = 3% = 0.03
The probability that an employee selected at random will need either eyeglasses or major dental work is given as
= P(eye glasses ) + P(major dental work) - P(eyeglasses and major dental work)
= 0.08 + 0.15 - 0.03 = 0.20
Therefore the Probability = 0.20
Answer:
X=10
Step-by-step explanation:
180-116=64
4x+7x+6+64=180
11x+70=180
11x=110
x=10
15 Gallons for 310 Miles
So Mile per Gallon = 310/15 = 20.66 (Ans)
Answer:
-96
Step-by-step explanation:
by replacing -2 on the place of x we get 12x-8= -96
Answer:
Step-by-step explanation:
Given that inflows are estimated at $50,000 annually for 3 years
Thus we find that total inflows are
I year 50000
II year 50000
III year 50000
150000
Maximum investment should be the one which equals present value of inflow
Interest 19%
Year Inflow Pre. Value
I 50000 42016.80672
II 50000 35308.24094
III 50000 29670.79071
Total inflow at present value 106995.8384
Max Amount to be invested 106995.8
Answer is 106995.80
