Step-by-step explanation:
how many ways can a president, a vice-president and a secretary be chosen from 20 members of a club assuming that one person cannot hold more than one position?
There are 6,840 ways.
How to find ways to choose a president, a vice-president, and a secretary from 20 members of a club?To solve this problem, we can use the permutation formula:
nPr = n! / (n - r)!
where n is the total number of members and r is the number of positions to be filled.
For the president position, there are 20 options. After the president is chosen, there are 19 members remaining for the vice-president position. Finally, for the secretary position, there are 18 members remaining.
Therefore, the total number of ways to choose a president, a vice-president, and a secretary from 20 members is:
20P1 * 19P1 * 18P1 = (20! / 19!) * (19! / 18!) * (18! / 17!) = 20 * 19 * 18 = 6,840
Therefore, there are 6,840 ways to choose a president, a vice-president, and a secretary from 20 members of a club.

Alex is 12 years older than George.
Carl is three times older than Alex
The sum of their ages is 68
Find the ratio of George's age to Carl's age to Alex's age.
Answer:
George : Carl : Alex = 1 : 12 : 4
Step-by-step explanation:
let a = Alex's age in years
let g = George's age in years
let c = Carl's age in years
Given:
Alex is 12 years older than George⇒ a = 12 + g
⇒ g = a - 12
Given:
Carl is three times older than Alex⇒ c = 3a
Given:
The sum of their ages is 68⇒ a + g + c = 68
Substitute the first two equations in the last equation and solve for a:
⇒ a + (a - 12) + 3a = 68
⇒ 5a - 12 = 68
⇒ 5a = 80
⇒ a = 16
Substitute the found value of a into the other equations to find g and c:
⇒ g = 16 - 12 = 4
⇒ c = 3(16) = 48
Therefore:
Alex = 16 years oldGeorge = 4 years oldCarl = 48 years oldRatio
George : Carl : Alex = 4 : 48 : 16
Reduce by dividing by 4 → 1 : 12 : 4

> Question 1 1 pts Write out the first 5 terms of the power series using a Math editor. Σ (3)" n! -æn+3 na
Question 4 1 pts Express the sum of the power series in terms of geometric series, and th
The sum of the power series may be expressed as the product of these geometric series:
\(∑ ((3^n)(n!))/(n+3) = (∑ (3^n)(n!) * (1/3)) * (Σ (1/3) * (1/(n+3)))\)
The energy collection can be written as:
\(∑ ((3^n)(n!))/(n+3)\)
To specify the sum of the electricity series in phrases of a geometric collection, we need to simplify the terms. Let's rewrite the series as follows:
\(∑((3^n)(n!))/(3(n+3)) = ∑ ((3^n)(n!))/3 * Σ (1/(n+3)\)
Now, we are able to see that the not-unusual ratio in the collection is 3. We can rewrite the collection as a geometric series with the use of the commonplace ratio:
\(∑ ((3^n)(n!))/(3(n+3)) = ∑ ((3^n)(n!))/3 * Σ (1/(n+3)\)
The first part of the series, Σ ((3^n)(n!))/three, is the geometric series with a not-unusual ratio of 3. We can express it as:
\(∑ ((3^n)(n!))/3 = ∑ (3^n)(n!) * (1/3)\)
The 2nd part of the collection, Σ (1/(n+3)), is a separate geometric series. We can specify it as:
\(∑(1/(n+3)) = Σ (1/3) * (1/(n+3))\)
Therefore, the sum of the power series may be expressed as the product of these geometric series:
\(∑ ((3^n)(n!))/(n+3) = (∑ (3^n)(n!) * (1/3)) * (Σ (1/3) * (1/(n+3)))\)
Please word that the expression for the sum of the electricity collection may further simplify depending on the values of n and the variety of the series.

Evaluate L-1 e2s+1 (3 s2-7,
The inverse Laplace transform of e^(2s+1)*7 is simply 7 times the inverse Laplace transform of e^(2s+1).
To evaluate L⁻¹[e^(2s+1)(3s²-7)], we need to find the inverse Laplace transform of the given expression. We can start by expanding the expression:
L⁻¹[e^(2s+1)(3s²-7)] = L⁻¹[e^(2s+1)*3s² - e^(2s+1)*7]
Now, we can use the linearity property of the inverse Laplace transform to split the expression into two separate terms:
L⁻¹[e^(2s+1)*3s²] - L⁻¹[e^(2s+1)*7]
The inverse Laplace transform of e^(2s+1)*3s² can be found using the derivative property and the table of Laplace transforms. The inverse Laplace transform of e^(2s+1)*7 is simply 7 times the inverse Laplace transform of e^(2s+1).
By applying the appropriate transformations and consulting the table of Laplace transforms, we can find the final result.

8. The prescriber has ordered heparin 20,000 units in 1,000 mL DsW IV over 24 hours. (a) How many units/hour will your patient receive? (b) At how many mL/h will you run the IV pump?
(a) The patient will receive 833 units/hour. +
(b) The IV pump will be set at 41.67 mL/hour.
To the number of units per hour, divide the total number of units (20,000) by the total time in hours (24). Thus, 20,000 units / 24 hours = 833 units/hour.
To determine the mL/hour rate for the IV pump, divide the total volume (1,000 mL) by the total time in hours (24). Hence, 1,000 mL / 24 hours = 41.67 mL/hour.

According to the same report, the 28.5 million passengers in 2018 represented a 6.7% increase in cruise passengers since 2017. how many cruise passengers must there have been in 2017? write your answer in millions and rounded to two decimal places.
The number of cruise passengers must there have been in 2017 is 26.7 million.
What is percentage?The term "percentage" comes from the Latin phrase "per centum," meaning "by the hundred." Percentages represent fractions with a denominator of 100. In other terms, it is the relationship between portion and whole in which the value of the whole is always assumed to be 100.
Now according to the question;
Let x represent the total number for cruise passengers during 2017.
In 2018, a 6.7% rise in x results in 28.5 million cruise passengers.
So, 106.7 % of x = 28.5
\(\begin{aligned}&\frac{106.7}{100} * x=28.5 \\&\frac{106.7 x}{100}=28.5\end{aligned}\)
Multiplying both sides by 100;
\(\begin{aligned}&\frac{106.7 x}{100} * 100=28.5 * 100 \\&106.7 x=2850\end{aligned}\)
Dividing both sides by 106.7;
\(\frac{106.7 x}{106.7}=\frac{2850}{106.7}\)
x = 26.7
Therefore, the number of cruise passengers in 2017 must have ranged from 26.7 million.

the lenght of time needed to complete a certain test is normally distrbuted with mean 43 minutes and standard deviation 8 minutes
The time needed to complete a certain test is a normal distribution with a mean of 43 minutes and a standard deviation of 8 minutes.
A normal distribution is a bell-shaped curve that represents a continuous probability distribution. The mean, represented by the symbol μ (mu), is the central tendency of the distribution, while the standard deviation, represented by the symbol σ (sigma), measures the spread of the data. In this case, the mean time needed to complete the test is 43 minutes, and the standard deviation is 8 minutes. This means that most people will take around 43 minutes to complete the test, with fewer people taking either longer or shorter times. The standard deviation of 8 minutes suggests that the time it takes people to complete the test can vary by up to 8 minutes from the mean. The normal distribution is a widely used statistical model, and understanding its properties can help us make predictions and draw conclusions about data.

For each problem, determine what will happen to the first factor?
10 x 1/2
15 x 7/2
When multiplying a whole number with a fraction, the first factor will be reduced to a fraction or a decimal, depending on the problem.
In both of the given problems, we are multiplying a whole number with a fraction. When we multiply a whole number with a fraction, we can simply multiply the whole number with the numerator of the fraction and keep the denominator as it is. So, in the first problem, we have 10 multiplied by 1/2. Multiplying 10 with 1 gives us 10, and then we divide it by 2, which gives us 5. Therefore, the first factor, which is 10, will be reduced to 5 in this problem.
In the second problem, we have 15 multiplied by 7/2. Multiplying 15 with 7 gives us 105, and then we divide it by 2, which gives us 52.5. Therefore, the first factor, which is 15, will be reduced to 52.5 in this problem.

A cylindrical rod measures 4 inches long and the circumference of one of its bases is 12π inches. the rod is cut into two equally-sized pieces and then all surfaces are painted. what is the area that is painted? use π≈3.14. enter your answer, rounded to the nearest tenth, in the box. in²
Rounding to the nearest tenth, the surface area painted is approximately 263.8 square inches.
We find the radius of the rod by dividing the circumference of one of its bases by 2π:12π inches / 2π = 6 inches / 2π = 6 / 2 = 3 inches
So, the radius of the rod is 3 inches.
Next, we find the surface area of one piece of the rod by using the formula for the surface area of a cylinder:
Surface area = 2πr(h + r)
Surface area = 2π * 3 * (4 + 3) = 2π * 3 * 7 = 42π square inches
Finally, we multiply the surface area of one piece of the rod by 2 to find the total surface area painted:
Surface area painted = 42π square inches * 2 = 84π square inches
Using π ≈ 3.14, the surface area painted is approximately 84 * 3.14 = 263.76 square inches.
Therefore, The rounding to the nearest tenth, the surface area painted is approximately 263.8 square inches.

which system of linear inequalities is represented by this graphed solution?
A. y > -1/2x + 2
y ≤ 3x - 1
B. y < -1/2x + 2
y ≥ 3x - 1
C. y > -2x + 2
y ≤ 1/3x - 1
D. y ≤ -1/2x + 2
y < 3x - 1
Answer:
B. y < -1/2x + 2 y ≥ 3x - 1Step-by-step explanation:
The gray shadowed area is below descending function and the line is dashed.
It means coefficient x is m<0 and the sign of inequality is y <
So the inequality wich fit it is y < -1/2x + 2
The blue shadowed area is above ascending function and the line is uninterrupted.
It means coefficient x is m>0 and the sign of inequality is y ≥
So the second inequality of system (y ≥ 3x - 1) also match.
The system of linear inequalities represented by this graphed solutions are y ≤ -1/2x + 2 and y < 3x - 1
The standard equation of a line is expressed as y = mx + b;
m is the slope of the lineb is the y-intercept of the lineFor the blue line, the y-intercept is at y = -1. For the slope passing through (0, -1) and (2, 5):
m = 5+1/2-0
m= 6/2
m = 3
The equation of the line is y = 3x - 1
Since the line is dashed and the left part shaded, the inequality expression will be y < 3x - 1
For the black line, the y-intercept is at y = 2. For the slope passing through (0, 2) and (4, 0):
m = 0-2/4-0
m= -2/4
m = -1/2
The equation of the line is y = -1/2x + 2
Since the line is solid and the lower part shaded, the inequality expression will be y ≤ -1/2x + 2
Hence the system of linear inequalities represented by this graphed solutions are y ≤ -1/2x + 2 and y < 3x - 1
