A system has three computers. Computer 1 works with a probability of 0.65; computer 2 works with a probability of 0.65; computer 3 works with a probability of 0.87. Suppose that the operations of the computers are independent of each other. Suppose that the system works only if at least one computer is working. What is the probability that the system works? Round your answer to four decimal places.
Answers
Probability that the system works is approximately 0.9841.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Let the three events be C₁, C₂ and C₃.
Probability that computer 1 works = P(C₁) = 0.65
Probability that computer 1 does not work = P(C₁') = 1 - 0.65 = 0.35
Probability that computer 2 works = P(C₂) = 0.65
Probability that computer 2 does not work = P(C₂') = 1 - 0.65 = 0.35
Probability that computer 3 works = P(C₃) = 0.87
Probability that computer 3 does not work = P(C₃') = 1 - 0.87 = 0.13
Let the event that at least one of the computer is working is S.
P(S) = 1 - P(no computer is working)
P(no computer is working) = P(C₁' ∩ C₂' ∩ C₃')
We have the operations of the computers are independent of each other.
P(C₁' ∩ C₂' ∩ C₃') = P(C₁') × P(C₂') × P(C₃')
= 0.35 × 0.35 × 0.13
= 0.015925
P(no computer is working) = 0.015925
P(S) = 1 - 0.015925
= 0.984075 ≈ 0.9841
Hence the required probability is 0.9841.

Answers
The number of girls in the next 200 girls surveyed that would choose their favorite sport as bowling are 8 girls.
What is percentage?We must divide the value by the entire value to find the percentage, and then multiply the resulting number by 100.
Given that 300 girls were asked to name their favorite sport. 12 of the girls named bowling as their favorite.
The percentage of girls that selected the sport is thus:
12/ 300 (100) = 4%
For the next 200 girls, calculate the 4% of the number to get the number of girls who like bowling:
200 (4%) = N
N = (200)(4/100)
N = 8

Prove that every non-empty finite set of positive integers contains a least element, by induction on n the size of the set.
Answers
The statement can be proven using mathematical induction. Let S be a non-empty finite set of positive integers.
Base case: If n = 1, then the only element in S is the least element.
Inductive step: Assume that the statement holds for all sets S of size n. Now, consider a set S of size n + 1. If a is the least element of S, then the set S' = S \ {a} has size n and, by the induction hypothesis, contains a least element b. Since a is the least element of S, it follows that b ≤ a. Then, either a = b or a < b.
If a = b, then a is the least element of S.If a < b, then b is the least element of S.Therefore, in any case, S contains at least element. This completes the proof by induction.

Answers
Answer:
The scale of a map tells you the relationship between the distance on the map and the actual distance in real life. In this case, the scale of the map is 1 inch : 6 miles, which means that 1 inch on the map represents 6 miles in real life.
To find out how many inches on the map 78 miles represents, you can use the following formula:
distance on the map = distance in real life / scale
So in this case:
distance on the map = 78 miles / 6 miles/inch
distance on the map = 78/6 inches
So 78 miles from the airport will be 13 inches on the map.

The graph shows the temperature of heated water at a certain heating time. What are the variables? Describe how the variables are related at various points on the graph.
Answers
The variables in the graph are temperature of the water (y-axis) and heating time (x-axis).
What are the variables?At various points on the graph, the relationship between the two variables can be seen as a linear increase in temperature with a corresponding increase in heating time. That is, as the heating time increases, the temperature of the water also increases.
The graph shows the relationship between two variables, heating time and temperature of heated water. The x-axis, or independent variable, represents the heating time, while the y-axis, or dependent variable, records the temperature of the heated water.
At the start of the graph, the heating time is 0 minutes and the temperature of the heated water is also 0 degrees Celsius. As the heating time increases, the temperature of the heated water gradually increases. At 10 minutes, the temperature of the heated water is approximately 20 degrees Celsius.
At 20 minutes, the temperature of the heated water is approximately 50 degrees Celsius. At 30 minutes, the temperature of the heated water is approximately 80 degrees Celsius. At 40 minutes, the temperature of the heated water is approximately 100 degrees Celsius and at 50 minutes, the temperature of the heated water is approximately 120 degrees Celsius.
The relationship between the two variables is linear; as the heating time increases, the temperature of the heated water also increases. The graph shows that the temperature of the heated water increases by approximately 20 degrees Celsius for every 10 minutes of heating time.

Answers
The mean of the sampling distribution of p is 0.45, (b) the standard deviation of p is 0.02, (c) yes, the Normal approximation can be used, and (d) the probability that more than half of the sample is in favour is 2.2523.
A) The mean of the sampling distribution of p is equal to the population proportion who favour giving vouchers to parents, which is 0.45.
B) The standard deviation of p can be calculated using the formula:
σ = √(p(1-p) / n)
where p = 0.45 and n = 500.
The standard deviation of p is approximately 0.02. This value represents the variability of the proportion of adults in samples of size n = 500 who favour the idea.
C) In order to use the Normal approximation for the distribution of p, the sample size n must be large enough such that np ≥ 10 and n(1-p) ≥ 10. For this problem, n = 500, p = 0.45, np = 500 * 0.45 = 225, and n(1-p) = 500 * (1-0.45) = 275, which are both larger than 10, so the Normal approximation can be used.
D) The probability that more than half of the sample is in favour can be found by subtracting the area under the standard normal curve to the right of z = 0.5 from 1.
z = (p - 0.45)/0.02
= (0.5 - 0.45)/0.02

What is length?Length is a concept used in various contexts to measure the size of an object or distance between two points. In geometry, length refers to the longest dimension of an object. In physics, length is a fundamental quantity that is used to measure the distance between two points. It is usually expressed in units such as meters, centimeters, and millimeters.
The missing side length is 7 yd. This is because the shape formed by these sides is a right triangle, and the Pythagorean theorem can be used to calculate the length of the missing side. The equation is [tex]a^{2} +b^{2} =c^{2}[/tex], where a and b are the two known side lengths and c is the missing side length. In this case, a = 6 yd and b = 8 yd, so [tex]c^{2} = 6^{2} +8^{2} =100[/tex]. The square root of 100 is 10, so c = 10 yd.

Going into the final exam, which will count as two tests, Sharon has test scores of 77, 84, 72,65, and 96. What score does Sharon need on the final in order to have an average score of 80 ?
Answers
On the final, the score that Sharon would need to have in order to have the average score of 80 is 3.
How to solve for the scoreLet's call the score Sharon needs on the final exam "x".
The total of all 6 test scores is: 77 + 84 + 72 + 65 + 96 + x
The average of all 6 test scores is: (77 + 84 + 72 + 65 + 96 + x) / 6 = 80
Expanding and solving for x, we have:
77 + 84 + 72 + 65 + 96 + x = 80 * 6
477 + x = 480
Subtracting 477 from both sides, we get:
x = 480 - 477
x = 3
So, Sharon needs a score of 3 on the final exam in order to have an average score of 80.

A deli owner has room for 55 containers of shredded Parmesan cheese. He has 5-oz and 10-oz containers, and a total
of 400 oz of cheese. If 5-oz containers sell for $9 and 10-oz containers sell for $17, how many of each should he sell to
maximize his revenue? What is his maximum revenue?
He should sell 5-oz containers and 10-oz containers to maximize his revenue.
Answers
Answer:
$630
Step-by-step explanation:
This problem can be solved using linear programming. Let x be the number of 5-oz containers and y be the number of 10-oz containers. The constraints are:
x + y = 55 (total number of containers)
5x + 10y = 400 (total amount of cheese in ounces)
x >= 0, y >= 0 (containers must be non-negative)
The objective is to maximize the revenue, which is given by 9x + 17y.
Using a linear programming solver, we find that the maximum revenue is obtained when x = 40 and y = 15. The maximum revenue is 9x + 17y = 9 * 40 + 17 * 15 = $630.
So, the deli owner should sell 40 5-oz containers and 15 10-oz containers to maximize his revenue, which is $630.

3. If 8,000 units are produced and sold, what is the variable cost per unit produced and sold?
Answers
The variable cost per unit produced and sold is, $11.50
What is average?In mathematics, Average is a value which we calculate by dividing the sum of values of all the data-set by the number of data-sets.
Average = sum of values of all the data-set/number of data-sets
The variable cost per unit produced and sold can be calculated by summing up the costs that vary with changes in production volume, and dividing the total by the number of units produced and sold.
For Martinez Company, the variable costs per unit are:
Direct materials = $ 6.00
Direct labor = $ 3.50
Variable manufacturing overhead = $ 1.50
Variable administrative expense = $ 0.50
Total variable cost per unit = $6.00 + $3.50 + $1.50 + $0.50
= $11.50
So, if 8,000 units are produced and sold, the variable cost per unit produced and sold would be $11.50.
