A power system will collapse if a ground fault occurs on any two of lines A, B, and C simultaneously. Assume that ground faults on lines A, B, and C are independent and have identical probability of 0.01. Hint: parts (a) and (b), use Bernoulli Trials; part (c), use Bayes Rule. a) What is the probability that the system will collapse
Answers
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
[tex]p = 3*(0.01)^2*0.99 + (0.01)^3 = 0.000298[/tex]
0.000298 = 0.0298% probability that the system will collapse

divide 49 ÷ 8 = and show your work
Answers
Answer:
6
Step-by-step explanation:
Place this digit in the quotient on top of the division symbol. Multiply the newest quotient digit (6) by the divisor 8 . Subtract 48 from 48 . The result of division of 48÷8 48 ÷ 8 is 6
The required, 49 divided by 8 gives 6 as the quotient and 1 as the remainder.
To divide 49 by 8, you can use long division to find the quotient.
Determine how many times the divisor (8) can fit into the new number (49). In this case, 8 goes into 49 six times. Subtract the result (48) from the number you brought down (49). 49 - 48 = 1. Write the result (1) below the line.
6
_______
8 | 49
- 48 (8 times 6)
______
1 (Remaining 1 after subtracting)
Therefore, 49 divided by 8 gives 6 as the quotient and 1 as the remainder.

Ms. Smith purchased ½ of a pound of grapes. She would like to make 1/12 of a pound portions for this week’s snacks. How many portions will she be able to make?
Answers
Answer:
There is no enough information to determine how many portions she will be able to make.
We need to know how many pounds of grapes will she needs to make a particular pounds portions for the snacks.
For example, if she needs 2 pounds of grapes to make 5 pounds portion for the snacks, and she purchase ½ pounds of grapes, we can determine how many pounds of portions for the snacks she will be able to make with this information.
Using a simple ratio
2:5 = ½:x
2/5 = ½/x
Multiplying both sides by x
(2/5)x = 1/2
Multiplying both sides by 5/2
x = (1/2)×(5/2)
x = 5/4
x = 1¼ pounds
Meaning she will be able to make 1¼ pounds of portion for snacks with ½ pounds of grapes.

How do i write the quotient as a mixed number?
Answers
Answer:
divide the numerator by the denomantor
Step-by-step explanation:
A fraction in which the numerator is smaller than the denominator, like 1/3 or 2/5 is called a proper fraction. A fraction in which the numerator is larger than or equal to the denominator, like 5/2, 17/3, or 6/6 is called an improper fraction. (To put it another way, a fraction with a value less than 1 is a proper fraction. A fraction with a value greater than or equal to 1 is an improper fraction.)
As we have shown above, mixed numbers can be written as improper fractions. Similarly, improper fractions can be written as mixed numbers.
What percent of 24 is

Answers
The value 18 is 75% of the number 24.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that there are two numbers 24 and 18. The percentage will be calculated as,
Percent = ( 18 / 24) x 100
Percent = 0.75 x 100

The perimeter of the parallelogram is of 44 units.
What is the perimeter of a figure?
The perimeter of a figure is given by the sum of all it's outside measures.
In this problem, since it is a parallelogram, we have that:
AD = BC
Hence:
3x - 1 = 2x + 2
x = 3
Hence:
AD = BC = 3x - 1 = 3(3) - 1 = 8
We also have that:
AB = DC
4y - 2 = 2y + 6
2y = 8
y = 4
Then:
AB = DC = 4y - 2 = 4(4) - 2 = 14
Thus, the perimeter is:
2 x (14 + 8) = 44 units.
