The probability that none of the three students volunteer at the hospital is 1/4. This means there is a 25% chance that none of the selected students will be volunteering at the hospital.
To find the probability, we first need to determine the total number of ways to select three students from the club, which is the combination of selecting three students from a total of four students. Using the formula for combinations, this is denoted as C(4, 3) and equals 4.
Next, we calculate the number of ways to select three students without any of them volunteering at the hospital. Since we want to exclude the students who volunteer at the hospital, we have only three remaining students to choose from. Hence, the number of ways to select three students without any of them volunteering at the hospital is C(3, 3) which equals 1.
Therefore, the probability that none of the three students volunteer at the hospital is 1 out of 4, or 1/4.

A company receives an average of 0.8 purchase orders per minute. The company wants to determine the probability of receiving 6 purchase orders in 5 minutes. What value should the company use for the mean to help alculate the probability?
The probability of receiving exactly 6 purchase orders in 5 minutes is 0.104, or about 10.4%.
The mean of the Poisson distribution is λ, which represents the average number of events in a given time period. In this case, the company receives an average of 0.8 purchase orders per minute, so the mean number of purchase orders in 5 minutes would be:
λ = (0.8 orders/min) x (5 min) = 4 orders
Thus, the Poisson distribution for the number of purchase orders in 5 minutes has a mean of 4. To calculate the probability of receiving 6 purchase orders in 5 minutes, we use the Poisson probability formula:
\(P(X = 6) = (e^(-λ) * λ^6) / 6!\)
where X is the random variable representing the number of purchase orders in 5 minutes.
Plugging in the values, we get:
\(P(X = 6) = (e^(-4) * 4^6) / 6! = 0.104\)
Therefore, the probability of receiving exactly 6 purchase orders in 5 minutes is 0.104, or about 10.4%.

$18What question is being asked in this word problem?
what is the regular cost of the t-shirt purchased by Jill.What is the regular price of the skirt?
$42How much money does Jill have left?
without considering sales tax, Jill has $90 - $31 = $59 left.If I use the sales tax from where I live, the sales tax = $1.86, so the money that Jill will have left = $59 - $1.86 = $57.14How much does the T-shirt normally cost?
$18 (same as question 1)What is the amount Jill pays in sales tax?
since you do not include the sales tax % in the question, I will simply use the sales tax from where I live = $31 x 6% = $1.86Step-by-step explanation:
skirt $21
t-shirt = p - $8
before sales tax, total cost was $31
$21 + p - $8 = $31
p = $18

Which of the following statements is not correct with regard to prior period adjustments?
a.Prior period adjustments arise from mathematical mistakes in a previous period.
b.Prior period adjustments are errors found in a period after the error occurred.
c.Prior period adjustments are reported as an adjustment to the ending balance of retained earnings in the current period.
d.All of these choices are correct.
The incorrect statement regarding the prior adjustment is option c. Prior period adjustments are not recognized as adjustments to the current year's closing retained earnings balance.
Prior period restatements relate to restatements made due to errors or omissions in the prior period financial statements. These adjustments may be the result of mathematical errors, errors discovered in later periods, or changes in accounting principles. The purpose of restoring prior periods is to ensure the accuracy and reliability of financial statements. Option a is correct. Prior period adjustments may be due to prior period mathematical errors. Option b is also correct. This is because prior adjustment from previous periods can be identified in the period after the error occurred.
However, option c is incorrect. This is because adjustments from prior periods are not reported as adjustments to the current period's ending retained earnings balance. Instead, retained earnings are reported directly on the statement of retained earnings or as a separate line item on the income statement. Prior period adjustments affect retained earnings balances, but are not treated as adjustments to period-end retained earnings balances. So the correct answer is d. Choices a, b, and c are correct except choice c.

A regular polygon has an exterior angle of 20° and a side measure of 6 centimeters. What is the areas of
the polygon?
The area of the polygon is approximately 497.41 square centimeters.
Define polygonA polygon is a two-dimensional geometric shape that is made up of straight lines connected end to end to form a closed shape. A polygon must have at least three sides, and each side must intersect with exactly two other sides.
The exterior angle of a regular polygon is equal to 360 degrees divided by the number of sides. So, if the exterior angle is 20 degrees, the number of sides can be found by dividing 360 by 20, which gives us 18.
Each interior angle of a regular polygon can be found using the formula:
Interior angle = (n - 2) x 180 / n
where n is the number of sides. For an 18-sided polygon, the interior angle is:
(18 - 2) x 180 / 18 = 160 degrees
Apothem = (Side length) / (2 x tan(π/n))
where n is the number of sides. Plugging in the values, we get:
Apothem = (6) / (2 x tan(π/18)) = 6 / (2 x 0.32492) ≈ 9.2367 cm
Finally, we can use the formula for the area of a regular polygon:
Area = (1/2) x Apothem x Perimeter
where Perimeter is just the side length multiplied by the number of sides. Plugging in the values, we get:
Perimeter = Side length x Number of sides = 6 x 18 = 108 cm
Area = (1/2) x 9.2367 x 108 ≈ 497.41 cm²
Therefore, the area of the polygon is approximately 497.41 square centimeters.

A service call for repairing your mower is $50 plus $80 per hour. how many hours did it take to service your mower if the charge was $90?
To determine the number of hours it took to service your mower when the charge was $90, we need to subtract the fixed service call fee ($50) from the total charge and then divide the remaining amount by the hourly rate of $80.
Let's denote the number of hours it took to service the mower as 'h'. The total charge for the service is given as $90.
To find the number of hours, we first subtract the fixed service call fee of $50 from the total charge: $90 - $50 = $40.
Next, we divide the remaining amount ($40) by the hourly rate of $80: $40 / $80 = 0.5 hours.
Therefore, it took 0.5 hours (or 30 minutes) to service your mower when the charge was $90.

0.4 how it come
\(10 \div 10\)
We need to remove the decimal and multiply and divide by 10, resulting in 0.4/1 x 10/10 = 4/104/10. This can be further reduced to 2/5, so 0.4 as a fraction is 4/10 or 2/5.
What is fraction?A fraction shows part of a whole. This whole can be a region or a collection. The word fraction is derived from the Latin word "fraction" which means 'to break'. The Egyptians, being the earliest civilization to study fractions, used fractions to resolve their mathematical problems, which included the division of food, supplies, and the absence of a bullion currency.
In Ancient Rome, fractions were only written using words to describe a part of the whole. In India, the fractions were first written with one number above another (numerator and denominator), but without a line. It was the Arabs only, who added the line which is used to separate the numerator and the denominator.
First, we need to remove the decimal.
For that, we multiply and divide by 10 as there is only one digit after the decimal.
We get, 0.4/1 x 10/10 = 4/10
4/10 can further be reduced to 2/5
Hence, we can say that 0.4 as a fraction is 4/10 or 2/5.

A motorcycle starts from rest and maintains a constant acceleration whose magnitude is 0.45 m/s².
a) Calculate how long it will take to travel a distance of 1.6 km.
b) How fast will it be in this time in m/s and in km/h?
a) If the motorcycle starts from rest, then we have an initial speed equal to zero (V0 = 0), with this we can choose a formula that does not contain the initial speed, now we also know that what it asks us is the time that it takes a certain speed to pass, so the formula we will use will be:
\(\bf{\displaystyle d=\frac{a{{t}^{2}}}{2}}\)
Clearing "t"
\(\boldsymbol{\sf{t=\sqrt{\dfrac{2d}{a} } } }\)
The distance is in Kilometers, we first need to pass this distance in meters, so we'll need to do our conversion:
\(\boldsymbol{\sf{1.6\not{km}*\dfrac{1000 \ m}{1\not{km}}=1600 \ m } }\)
1.6 km = 1600m
Substituting our data into the formula:
\(\boldsymbol{\sf{t=\sqrt{\dfrac{2d}{a} }=\sqrt{\dfrac{2(1600 \ m) }{9.45 \ \frac{m}{s^2} } }=84.32 \ s } }\)
So the motorcycle will take 84.32 seconds to travel 1600 meters.
b) Since we are asked to obtain the speed in the time it took for the 1600 meters, we are going to use the following formula.
\(\boldsymbol{\sf{V_{f}=at }}\)
Substituting our data:
\(\boldsymbol{\sf{V_{f}=at=\left(0.45 \ \dfrac{m}{\not{s^{2}} }\right)(84.23 \ s)=37.94 \ \dfrac{m}{s} }}\)
In order to express the final result of the speed, in terms of km/h, we would only apply the conversion factors.
\(\boldsymbol{\sf{V_{f}=37.94\dfrac{\not{m}}{\not{s}}*\dfrac{1 \ km}{1000\not{m}}*\dfrac{3600\not{s}}{1 \ h}=136.58 \ \dfrac{km}{h} }}\)

Assume that this proportion is true for ALL children (e.g. that this proportion applies to any group of children), and that the remainder of the questions in this section apply to selections from the population of ALL children. b) If 8 children are chosen, the probability that exactly 4 would draw the nickel too small is: c) If 8 children are chosen at random, the probability that at least one would draw the nickel too small is:
The probability that at least one child would draw the nickel too small is: P(X ≥ 1) = 1 - P(X = 0).
b) To find the probability that exactly 4 children would draw the nickel too small, we can use the binomial probability formula. The formula is: P(X = k) = (nCk) * (p^k) * (q^(n-k)), where n is the number of trials, k is the number of successes, p is the probability of success, and q is the probability of failure.
In this case, n = 8 (as 8 children are chosen), k = 4 (as exactly 4 children drawing the nickel too small), p = 0.15 (as the probability of a child drawing the nickel too small), and q = 1 - p = 1 - 0.15 = 0.85.
So, the probability that exactly 4 children would draw the nickel too small is: P(X = 4) = (8C4) * (0.15^4) * (0.85^(8-4)).
c) To find the probability that at least one child would draw the nickel too small, we can use the complement rule. The probability of at least one success is equal to 1 minus the probability of no success.
The probability of no success (all children drawing the nickel of the right size) is given by: P(X = 0) = (8C0) * (0.15^0) * (0.85^8).
Therefore, the probability that at least one child would draw the nickel too small is: P(X ≥ 1) = 1 - P(X = 0).
