Answer:

57120

Step-by-step explanation:

Total number of people in a committee = 17

We need to select a president, a vice-president, a secretary, and a treasurer from the committee .

We need to find the number of ways in which these four positions can be filled .

Also, assume that a committee member can hold at most one of these offices.

For post of president , we can choose from 17 people

For post of vice - president , we are left with 16 choices only as one person has already been selected for post of president .

For post of a secretary  , we are left with 15 choices only as two persons have already been selected for post of president and vice - president .

For post of a treasurer  , we are left with 14 choices only as three persons have already been selected for post of president , vice - president and treasurer .

So, number of ways in which these four positions can be filled  = [tex]17\times 16\times 15\times 14 = 57120[/tex]

To determine the number of ways to fill four distinct positions from 17 people where each person can only hold one position, we calculate the permutations, resulting in 17 x 16 x 15 x 14 = 40,320 different ways.

The question pertains to a combinatorial mathematics problem, specifically involving permutations. Given a committee consisting of 17 people, we need to determine in how many different ways four distinct positions (president, vice-president, secretary, and treasurer) can be filled. To solve this, we assume that no person can hold more than one office.

To choose the president, there are 17 possible candidates. Once the president is chosen, there are 16 remaining candidates for the vice-president. Similarly, there are 15 candidates for the secretary position after the president and vice-president have been chosen, and finally, 14 candidates for the treasurer. The number of permutations is the product of these choices, which is calculated as 17 x 16 x 15 x 14.

The calculation yields 40,320 different ways to fill the four positions. This calculation is an example of using factorial notation in permutations where the general formula is n!/(n-r)!, with n representing the total number to choose from, and r is the number to be chosen.

Answer: y= -1/2x + 3/4

Step-by-step explanation: For a line in the for of y=mx + b, the slope is m and y intercept is b.

Answer:

y = - [tex]\frac{1}{2}[/tex] x + [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 6x + 12y = 9 into this form

Subtract 6x from both sides

12y = - 6x + 9 ( divide all terms by 12 )

y = - [tex]\frac{6}{12}[/tex] x + [tex]\frac{9}{12}[/tex], that is

y = - [tex]\frac{1}{2}[/tex] x + [tex]\frac{3}{4}[/tex]

Answer:

Time to decay will be 377.7 days.

Step-by-step explanation:

Decay of an radioactive element is represented by the formula

[tex]A_{t}=A_{0}e^{-kt}[/tex]

where [tex]A_{t}[/tex] = Amount after t days

[tex]A_{0}[/tex] = Initial amount

t = duration for the decay

k = decay constant

Now we plug in the values in the formula

[tex](1-0.12)x=xe^{-30k}[/tex]

[tex](0.88)x=xe^{-30k}[/tex]

[tex]0.88=e^{-30k}[/tex]

Now we take natural log on both the sides

ln(0.88) = [tex]ln(e)^{-30k}[/tex]

ln(0.88) = -30k(lne)

-30k = -0.1278

k = [tex]\frac{.1278}{30}[/tex]

k = [tex]4.261\times 10^{-3}[/tex]

Now we have to calculate the duration for the decay of 50 mg sample to 10 mg.

[tex]A_{t}=A_{0}e^{-kt}[/tex]

We plug in the values in the formula

10 = 50[tex]e^{-4.261\times 10^{-3}\times t}[/tex]

[tex]e^{-4.261\times 10^{-3}\times t}=\frac{10}{50}[/tex]

[tex]e^{-4.261\times 10^{-3}\times t}=0.2[/tex]

We take (ln) on both the sides

[tex]ln(e^{-4.261\times 10^{-3}\times t})=ln(0.2)[/tex]

[tex]-4.261\times 10^{-3}\times t=-1.6094[/tex]

t = [tex]\frac{1.6094}{4.261\times 10^{-3} }[/tex]

t = 0.37771×10³

t = 377.7 days

Therefore, time for decay will be 377.7 days.

Answer:

10.5

Step-by-step explanation:

got it on the test

The length of line segment AC in triangle ABC is 12.3 meters, derived using the sine function and the given angle and side.

To find the length of Line segment AC in the given right angle triangle ABC, we can use the trigonometry functions. Since we are given the length of side CB and the measure of angle BAC, we can apply the sine function. The sin of an angle in a right angle triangle is the length of the opposite side (which in this case is the length of AC we're trying to find) divided by the length of the hypotenuse (which in this case is length CB = 15 m).

So, sin(55 degrees) = Length of AC / 15 m. Solving this equation for Length of AC produces: Length of AC = 15 m * sin(55 Degrees). Plugging in the value of sin(55 degrees) approximately as 0.819 gives a Length of AC approximately equal to 12.3 m. "So the length of the line segment AC is 12.3 m".

Answer:

Probabilities are usually given in percentages.

Odds can have a value of 0-infinity & are in the form of a ratio. Odds can be given in 2 different ways: Odds in favor & Odds against.

*Probability of drawing a green

marble is 50%

*Odds if drawing a green marble

are 5:5

The probability of drawing a green marble is 1/2 and the odds are 1:1. The difference between probability and odds is explained.

The probability of drawing a green marble from the bag can be calculated by dividing the number of green marbles by the total number of marbles in the bag. In this case, there are 5 green marbles and a total of 10 marbles, so the probability is 5/10 or 1/2.

Odds, on the other hand, represent the ratio of the number of favorable outcomes to the number of unfavorable outcomes. In this case, since there are 5 green marbles and a total of 5 marbles that are not green (3 blue marbles and 2 red marbles), the odds of drawing a green marble are 5:5 or 1:1.

The difference between probability and odds is that probability is a measure of the likelihood of an event occurring, while odds represent the ratio of favorable to unfavorable outcomes.

Answer:

grams of gold=8x10^12 g

Step-by-step explanation:

first we calculate the volume of the ocean this is achieved by multiplying the area by the depth

A=3.63x10^8  km^2=3.63x10^14   m^2

V=AxL

V=3.63x10^14 x 3800=1.3797x10^18m^3=1.3797x10^21L

then we multiply the volume in liters by the concentration of gold in the ocean per liter

grams of gold=1.3797x10^21   x    5.8x10^-9=8x10^12 g

Answer:

8.00 *10¹² g

Step-by-step explanation:

We must calculate the grams of gold in the ocean.

We are given the concentration of dissolved gold as grams per Liter.

So we need to first calculate the Liters of the ocean, that is, the volume.

We can calculate the volume of the ocean assuming a prism shape as:

Volume = Area x Depth

We should first convert the area from km² to m² so that the units are consistent:

[tex]3.63 *10^{8}  km^{2} * (\frac{1000 m}{1 km} )^{2} = 3.63 *10^{14}  m^{2}[/tex]

So the volume:

Volume = 3.63 x10¹⁴ m² * 3800 m = 1.38 x10¹⁸ m³

Since we have the concentration given in Liters, lets convert the volume to Liters, knowing that 1 L = 1000 m³:

[tex]1.38 *10^{18} m^{3} *\frac{1000 L}{1 m^{3} } = 1.38 *10^{21} L[/tex]

Knowing that the concentration of gold is 5.8 *10⁻⁹ grams per Liter, we can multiply this value by the Liters of the ocean to calculate the grams of gold:

5.8 *10⁻⁹ g/L  x 1.38 *10²¹ L = 8.00 *10¹² g

There are 8.00 *10¹² grams of gold in the ocean

Answer:

The difference in per-mile costs for the two companies is $0.12

Step-by-step explanation:

Gabi sets up the equation [tex]0.22m+7.20=0.1m+8.40[/tex] to find out after how many miles, m, the companies will charge the same amount.

The first company charges [tex]c_1=0.22m+7.20[/tex] for m miles driven.

The second company charges [tex]c_2=0.1m+8.40[/tex] for m miles driven.

In both these functions, numbers 7.20 and 8,40 represent the initial fee the companies charge.

Numbers 0.22 and 0.1 represent per-mile costs.

Thus, the difference in per-mile costs is [tex]0.22-0.1=0.12[/tex]

Another way to solve this problem is to find the cost per mile driven for each company:

1. Cost per-mile 1st company

[tex]c_1(0)=0.22\cdot 0+7.20=7.20\\ \\c_1(1)=0.22\cdot 1+7.20=7.42\\ \\c_1(1)-c_1(0)-7.42-7.20=0.22[/tex]

2. Cost per-mile 2nd company

[tex]c_2(0)=0.1\cdot 0+8.40=8.40\\ \\c_2(1)=0.1\cdot 1+8.40=8.50\\ \\c_2(1)-c_2(0)=8.50-8.40=0.1[/tex]

3. Difference:

Answer:

The answer to your question is:  BC = √65 or 8.05 u

Step-by-step explanation:

Data

AD = 12 u

BD = 15 u

AC = 4 u

BC = ?

First calculate the length of AB using the pythagorean theorem

 BD² = AB² + AD²

 AB² = BD² - AD²

 AB² = 15² - 12²

 AB² = 225 - 144

 AB² = 81

 AB = 9 u

Now, use the pythagorean theorem to find BC

 AB² = BC² + AC²

 BC² = AB² - AC²

 BC² = 9² - 4²

 BC²  = 81 - 16

 BC² = 65

 BC = √65 or 8.05 u

Answer:

Answer:

15 miles per hour is the speed of the slower train.

Step-by-step explanation:

As given in the figure attached,

Let the speed of train 1 is v and train 2 is u.

Therefore, distance traveled in 2 hours by train 1 will be = 2v miles

and distance traveled by train 2 will be = 2u miles

Now we can see in the figure a right angle triangle is formed by the two trains.

AB² + BC² = AC²

(2v)² + (2u)²= (65.30)²

4v² + 4u² = 4264.09

Now we divide this equation by 4

v² + u² = 1066.02

If speed of the slower train is v miles per hour then as per statement of the question.

u = v - 14

v = u + 14

By putting the value of v in the equation

(u + 14)² + u² = 1066

u² + 196 + 28u + u² = 1066

2u² + 28u + 196 = 1066

2u² + 28u + 196 - 1066 = 0

2u² + 28u - 870 = 0

By diving this equation by 2

u² + 14u - 435 = 0

u² + 29u - 15u - 435 = 0

u(u + 29) - 15(u + 29) = 0

(u + 29)(u - 15) = 0

u = -29, 15

Since speed can not be with negative notation so u = 15 miles per hour will be the speed.

Therefore, 15 miles per hour is the speed of the slower train.

Answer:

The answer is C

Step-by-step explanation:

The measurement of angle POS is 20 and POQ is 40

OS is an angle bisector of ∠POQ.  This means it splits ∠POQ into two congruent pieces.  

This tells us that ∠POS+∠SOQ = ∠POS+∠POS = ∠POQ.

If m∠POS = 20, this means that m∠POQ = 20+20 = 40°.

Answer:

The correct option is C) m∠POS = 20°, m∠POQ = 40°,

Step-by-step explanation:

Consider the provided figure.

Meg constructed triangle POQ and then used a compass and straightedge to accurately construct line segment OS.

From the given figure it is clear that OS is angle bisector of POQ,

[tex]\angle POQ=\angle POS+\angle QOS[/tex]

[tex]\angle POS=\angle QOS[/tex]    ∴ angle bisector

[tex]\angle POQ=\angle POS+\angle POS=2\angle POS[/tex]

Thus, the measure of ∠POQ is double the measure of ∠POS.

There is only one option in which m∠POQ is double the m∠POS.

Therefore, the correct option is C) m∠POS = 20°, m∠POQ = 40°,

Step-by-step explanation:

step 1

Find the area of each slice of pizza

[tex]A=\frac{1}{8}\pi r^{2}[/tex]

we have

[tex]r=16/2=8\ in[/tex] ----> the radius is half the diameter

substitute

[tex]A=\frac{1}{8}\pi 8^{2}[/tex]

[tex]A=8\pi\ in^{2}[/tex]

step 2

Find the area of John's part (area of shaded triangle)

The measure of the central angle of each slice of pizza is equal to

[tex]360\°/8=45\°[/tex]

so

the height of triangle is equal to the base

Let

x ---->the base of the shaded triangle

[tex]cos(45\°)=\frac{x}{r}[/tex]

[tex]cos(45\°)=\frac{x}{8}[/tex]

Remember that

[tex]cos(45\°)=\frac{\sqrt{2}}{2}[/tex]

substitute

[tex]\frac{\sqrt{2}}{2}=\frac{x}{8}[/tex]

solve for x

[tex]x=4\sqrt{2}\ in[/tex]

Find the area of shaded triangle

[tex]A=(1/2)(4\sqrt{2})(4\sqrt{2})=16\ in^2[/tex]

step 3

Find the area of Lee's part

The area of Lee's part is equal to the area of two slices of pizza minus the area of two triangles

so

[tex]2(8\pi)-2(16)=(16\pi-32)\ in^2[/tex]

assume

[tex]\pi =3.14[/tex]

[tex](16(3.14)-32)=18.24\ in^2[/tex]

so

Lee's part is greater than John part's

Find the difference

[tex]18.24-16=2.24\ in^2[/tex]

therefore

Lee has more pizza

Lee has 2.24 in^2 more than John

Without exact dimensions of Lee's cut, we can't calculate the precise difference in area after he cuts off an edge, but John likely has more pizza since his slice is unmodified.

The student's question involves comparing areas of pizza slices after one has been modified by cutting off an edge. To answer who has more pizza and by how much, we need to calculate the area of the pizza slices. The original pizza is 16 inches in diameter, and when divided into 8 equal slices, each slice is a sector of a circle with a central angle of 45 degrees. If Lee cuts off an edge and John takes an unmodified triangular slice, John would likely have more pizza because Lee's slice has been reduced in size. However, without knowing the exact dimensions of the removed edge, we can't calculate the precise difference in area.

-3⁄14 - 3⁄14

_______________

3 11⁄14 = b

y = -1½x + 3 11⁄14 >> New equation

I am joyous to assist you anytime.

Answer:

Step-by-step explanation:

So a few things to know before hand.  Slope ntercept form is y = mx + b where m is the slope, and in this form that will always make b the y intercept.

A perpendicular slope is pretty easy to find.  Of course, perpendicular means it intersects that first line at a 90 degree angle.  So the x and y axis themselves are perpendicular.  Anyway, if you know the slope of the line, a perpendicular slope is -1/m where m is the slope.  S taking the simplest example, in the graph of just x, the slope is 1, so the perpendicular slope is -1/1 or just -1.

The last thing is to know how to write the equation of a linear function when you know a point and its slope.  if you have the slope m and a point on the graph (a,c) you can use the point slope form which is this.  y - c = m(x - a) where you solve for y.  x an y stay as variables here.

Now knowing all that we can start.  First we want to put the original graph into slope intercept form, which is pretty easy.  Just manipulate the equation.

2x - 3y = 4

2x -4 = 3y

y = (2x - 4)/3

y = 2/3 x - 4/3

so m = 2/3 and b = -4/3

Now, we have the slope of this line and want the slope of a perpendicular line.  Like I mentioned before the slope is -1/m so in this case that's -1/(2/3) = -3/2  Let me know if you don't get how that was gotten.

Now that we kno the perpendicular slope, we can make a perpendicular line.  How do we make a line when we know the slope and a point?  Keep in mind the point is (-1/7, 4)

y - c = m(x-a)

y - 4 = -3/2(x + 1/7)

y - 4 = -3/2 x - 3/14

y = -3/2 x + 53/14

If it weren't in slope intercept form you'd have to put it in that, but I took care of it in the process, so here's the answer.  Let me know if there's anything you don't understand.  

Answer:

See below

Step-by-step explanation:

a + 133 = 180 because they are supplementary angles. (adjacent angles that form a straight angle)

a = 47 (you substract 133 at each side of the previous equation, leaving that a = 47)

m || n Since "a" measure the same as the angle in the figure that measures 47 both are corresponding angles, therefore m and n are parallels

Answer:

Step-by-step explanation:

It is called adjacent angles to all pairs of angles (2 angles) that are consecutive (that is, have the vertex and one side in common) and supplementary ( the sum of both angles results in 180 °; that is, a straight angle). Graphically, two opposite semi-lines are observed. You can see two adjacent angles in the image.

A case of consecutive angles is shown between a"" and 133 °, because they form a straight angle and are separated by a common side.  Then "a" and 133 ° add up to 180 °. In this way you can know what is the value of "a".

a+133°=180°

a=180°-133°

a=47°

The relative position of the angles with respect to the straight lines makes those angles receive specific names. Thus, it is called corresponding angles to those that are located on the same side of the parallels and on the same side of the transversal. These angles are equal.

Note that the other angle given as data is 47 °. This angle has the same value as "a" and as both angles are on the same side of the transverse, so that they are corresponding m must be parallel to n.

Step-by-step explanation:

Given that in  a study of a weight loss​ program, 4 subjects lost an average of 48 lbs.

It is found that there is about a 32​% chance of getting such results with a diet that has no effect.

The results do not appear to have statistical significance.  The reasons are

1) Sample size of 4 is very small not even meeting the bare minimum

2) Sample of 4 cannot be taken to represent the population

3) Whether bias was there in the selection of sample is not known.

4) Std deviation is not considered which is very important while concluding results.

Step-by-step explanation:

15+5=20+9=29

Addition

By using the associative property of addition, we calculate that Brooke has 29 problems for homework. This total is found by adding 15 math problems, 5 social studies problems, and 9 science problems together.

To calculate how many problems Brooke has for homework, we need to add together the numbers of math, social studies, and science problems. This operation is typically done using the property of addition. The property of addition we've applied here is known as the Associative Property of Addition. This property states that the way numbers are grouped does not change their sum.

So, if Brooke has 15 math problems, 5 social studies problems, and 9 science problems, we calculate the total as follows: 15 (math) + 5 (social studies) + 9 (science) equals 29 problems. So, Brooke has 29 problems to do for her homework.

Step-by-step explanation:

Answer: The value of cross price elasticity is 1.6.

Step-by-step explanation:

Since we have given that

Percent change in price = 10%

Percent change in quantity = 16%

So, we need to find the cross price elasticity between the two movie club memberships.

As we know the formula for cross price elasticity :

[tex]\dfrac{\%\text{change in demand}}{\%\text{change in price}}\\\\=\dfrac{16}{10}\\\\=1.6[/tex]

Hence, the value of cross price elasticity is 1.6.
