SIZIF [17.4K]

Answer:

yes. The cost of the insurance is less than the probability cost of the operation

Step-by-step explanation:

yes. The cost of the insurance is less than the probability cost of the operation

The cost of health insurance = $1200

Cost of dramatic injury operation= $500,000

chances of need of operation= 47.3% over a 20 years period

the amount of pay insurance after 20 years= 20\times 1200= 240,00

probable  of cost operation= 0.473*500,00= $236,500

clearly the cost of insurance is less than the probable  cost of operation.

18.4 + 8w = 6 (9w - 4.6)
svp [43]

Answer:


Step-by-step explanation:

18.4 + 8w = 6(-4.6 + 9w)

18.4 + 8w = (-4.6 * 6 + 9w * 6)

18.4 + 8w = (-27.6 + 54w)

18.4 + 8w + -54w = -27.6 + 54w + -54w

18.4 + -46w = -27.6 + 54w + -54w

18.4 + -18.4 + -46w = -27.6 + -18.4


Combine like terms: 18.4 + -18.4 = 0.0

0.0 + -46w = -27.6 + -18.4

-46w = -27.6 + -18.4

-27.6 + -18.4 = -46

-46w = -46


w = 1


Simplifying

w = 1
