a manufacturing production line breaks down two times a week on average. what is the probability that the interarrival times between breakdown will be less than 2 days?
The probability that there will be less than two days between manufacturing production line outages is approximately 0.553, or 55.3%.
We need to make some assumptions in order to calculate the probability that the time intervals between manufacturing production line breakdowns will be shorter than two days. Assume that the intervals between breakdowns have an exponential distribution with a mean of 3.5 days (1/2 times per week).
The probability that an interarrival time is fewer than two days can be calculated using the exponential distribution formula as follows:
P(X < 2) = 1 - e(-2/3.5)
where "X" stands for the duration in between breakdowns.
When we condense the expression, we get:
P(X < 2) = 0.553
Therefore, The probability that there will be less than two days between manufacturing production line outages is approximately 0.553, or 55.3%.

. three coins are tossed up in the air, one at a time. what is the probability that two of them will land heads up and one will land tails up?
The probability of receiving two heads and one tail is 3/8, or 0.375.
One of the areas of probability theory is the estimation of the chance of experiments occurring. Using a probability, we can calculate everything from the likelihood of getting heads or tails when flipping a coin to the likelihood of making a research error, for example. It is essential to appreciate the most basic definitions of this branch, such as the formula for computing probabilities in equiprobable sample spaces, the likelihood of two events joining together, the probability of the complementary event, etc., in order to properly understand it .Probability refers to potential.

a cafe lets you order a deli sandwich your way. there are : e1, six choices for bread; e2, four choices for meat: e3, four choices for cheese; and e4, 12 different garnishes (condiments). what is the number of dffferent sandwich possibilities, if you may choose one bread, 0 or 1 meat, 0 or 1 cheese, and from 0 to 12 condiments? (multiplication principle) (not allowing repetition for bread, meat and cheese) (allowing repetition for condiments)
The number of different sandwich possibilities is 1081.
To calculate this, we must use the multiplication principle. We will begin by calculating the number of possibilities for the bread, meat, and cheese. There are 6 different breads, 4 different meats, and 4 different cheeses. So, there are 6 x 4 x 4 = 96 possible combinations for the bread, meat, and cheese. Next, we must calculate the number of possibilities for the condiments. Since we are allowing repetition for the condiments, we can calculate the possibilities by multiplying 12 (the number of condiments) by itself. So, there are 12 x 12 = 144 possibilities for the condiments. Lastly, we can multiply 96 (the number of bread, meat, and cheese combinations) by 144 (the number of condiment combinations). This yields 1081 different sandwich possibilities.

is it possible for a system of linear equations with fewer equations than variables to have no solution? if so, give an example.
Yes, it is possible for a system of linear equations with fewer equations than variables to have no solution. For example, consider the system of linear equations: x + y = 1, x + 2y = 3, x + 3y = 4.
The system of linear equations given is:
x + y = 1
x + 2y = 3
x + 3y = 4
This system has two variables (x and y) but only three equations. We can add and subtract the equations to see that the first two equations imply that y = 2, but the third equation implies that y = 1. This is a contradiction, so there is no solution to the system.
To solve this system, we can use techniques such as elimination or substitution. For example, we can subtract the first equation from the second equation to eliminate x, and get:
[tex]x + 2y - (x + y) = 3 - 1[/tex]
[tex]y = 2[/tex]
Similarly, we can subtract the first equation from the third equation to eliminate x, and get:
[tex]x + 3y - (x + y) = 4 - 1[/tex]
[tex]2y = 3[/tex]
[tex]y = 3/2[/tex]
However, we obtained two different values for y, which is a contradiction. As a result, the equation system cannot be solved. In other words, there is no pair of values of x and y that satisfy all three equations simultaneously.
Geometrically, this means that the system of equations represents three planes in three-dimensional space. However, these planes do not intersect at a common point, so there is no solution to the system.

We will use the SAS condition for congruency of two triangles
SAS (Side-Angle-Side)
If any two sides and the angle included between the sides of one triangle are equivalent to the corresponding two sides and the angle between the sides of the second triangle, then the two triangles are said to be congruent by SAS rule.
In the two triangles ΔHIK and ΔJIK we have
m∠4 = m∠3 (given)
HK ≅ KJ
IK is the common side
So the two sides HK and IK are equal and the included angles ∠4 and ∠3 are also equal
So by SAS, the two triangles are equal
So m∠2 = m∠1

When Cheryl’s phone battery is 55% charged, she knows it will last for another 1.5 hours. If Cheryl’s phone battery loses its charge at a constant rate, how long, in hours, will it last when it is fully charged?
Create a proportion using the given information to determine how long it will take for Cheryl's phone battery to totally drain. Total time divided by the remaining charge's percentage equals the remaining time (total charge)
What battery loses its charge at a constant rate?Enter these values because Cheryl is aware that the battery will continue to operate for 1.5 hours at a 55% charge. 1.5 / 0.55 = (total time) / 1 = (total time) / (total charge) (amount of time left) / (remaining percentage of the charge)
When we calculate the total amount of time, we get:
Time: 2.727 hours (1.5 / 0.55 × 1) * 1
To determine how long the battery will survive after fully charged, we may simply reverse the rate of discharge:
Total time / Total charge / (time left) / 1 = Total time / 100 (time left) = Total time / 100 (time left) (percent charge remaining)
The battery's lifespan after being completely charged is as follows:
(Total time) / 100 divided by the remaining time gives us 2.727 / 100 or 0.02727 hours.
As a result, after 1.64 minutes, or 0.02727 hours, Cheryl's phone battery will be fully charged.

a basketball player makes 80% of her free throws. what is the standard deviation of the successes from 100 free throws?
Since 80 out of 100 free throws were successful, the standard deviation of the success rate would be 8, and the standard deviation of a binomial distribution is the square root of (p*q)/n, where p is the probability of success, q is the probability of failure (1-p), and n is the total number of trials.
Standard deviation is calculated as follows:
p*q/n = 0.8*0.2/100 = 0.0016 = 0.04 = 8
Since 80% of 100 equals 80 successful free throws, the standard deviation of the successes from 100 free throws would be 8. The dispersion in a set of data is measured by standard deviation. A binomial distribution's standard deviation is equal to the square root of (p*q)/n, where p is the success probability, q is the failure probability (1-p), and n is the number of trials. Since the success rate in this instance is 80%, p = 0.8, q = 0.2, and n = 100. The standard deviation is then equal to the square root of (p*q/n): (0.8*0.2/100) = (0.0016) = (0.04), which equals 8. Therefore, the standard deviation of the successes from 100 free throws for a basketball player who makes 80% of them would be 8.
