The owner of a small firm has just purchased a personal computer, which she expects will serve her for the next two years. The o

tatiyna

Answer: 26 dollars

Step-by-step explanation:

The owner needs to consider that:

To measure the risk she can multiply the probability of an event to happen (P)* the impact (I) (in this case the impact is the cost).

All these eventes can be considered as independent between each other (no correlation), so you can add their P*I.

In this case:

P1*I1= 1%*550=5.5

P2*I2=6%*150=9

P3*I3=15%*100=15

So, the expected value of what she may spend for repairng is = P1*I1+P2*I2+P3*I3= 5.5+9+15= 29.5

She shoould not spend more than 29.5 dollars, otherwise, she will spend more in the surge supresor than in expected reapring value

While in Europe, if you drive 117 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per lite

Hoochie [10]

You would spend $63.58 on gas per week.

Step-by-step explanation:

Given,

Distance per day = 117 km

Distance in a week = 117*7 = 819 km

1 km = 0.6214 mile

819 km = 819*0.6214 = 508.93 miles

Car's mileage = 42.0 mi/gallons

Let,

x be the gallons for 508.93 miles

x gallons = $\frac{508.93}{42}=12.12$

Therefore,

12.12 gallons of gas is needed for one week.

1 US gallon = 3.785 liters

12.12 gallons = 12.12*3.785

12.12 gallons = 45.87 liters

Cost of gas per liter = 1.10 euro

Cost of 45.87 liters = 1.10*45.87 = 50.457 euros

1 euro = $1.26

50.457 euros = 1.26*50.457 = $63.58

You would spend $63.58 on gas per week.
