A power system will collapse if a ground fault occurs on any two of lines A, B, and C simultaneously. Assume that ground faults
nadya68 [22]

Answer:

0.000298 = 0.0298% probability that the system will collapse

Step-by-step explanation:

Number of possible ways the system can fail:

2 lines from a set of 3 fail, or all three fail.

Two from a set of 3:

Can be A and B, A and C, or B and C. Three possible outcomes then.

The probability of each is:

0.01*0.01*0.99

Two failling, each with 0.01 probability, and 1 working, with 0.99 probability.

All three:

Each with 0.01 probability.

a) What is the probability that the system will collapse

Both cases, so

p = 3*(0.01)^2*0.99 + (0.01)^3 = 0.000298

0.000298 = 0.0298% probability that the system will collapse

How much does it cost to travel one mile? Round your answer to the nearest A white water rafting company sells tickets for an 18
frosja888 [35]

Answer:

1 mile = $14

Step-by-step explanation:

We know how much the 18-mile trip is for sale, so to know how much 1-mile sale we just have to divide the total amount by the amount of miles

18 miles = $ 249

1 mile =

1 mile = 249 / 18

1 mile = 13.83

To know what the nearest dollar value is, we only have to check if what is after the whole number is May or less than .50

is larger so we round to the largest number that is 14

nearest dollar = $14

Account A: $300 monthly deposits, interest rate is 4.2%. Account B: $250 monthly deposits, interest rate is 5.1%. Which account
Elan Coil [88]

Answer:

A

Step-by-step explanation:

We have to determine the future value of the annuity to determine which account has a greater value

Future value = Amount x annuity factor

annuity factor = Annuity factor = {[(1+r)^n] - 1} / r

Account A = 300 x[ (1.042)^15 - 1 ] / 0.042 = $6097.14

Account B = 250  x[ (1.051)^15 - 1 ] / 0.051 = $5435,42

Account A will be greater
