Bian wants to write the integers 1 to 9 in the nine boxes shown so that the integers in any three adjacent boxes add to a multiple of 3. In how many ways can she do this?​

Answers

Answer: To satisfy the given condition, we need to place the numbers in the boxes in a way that the sum of any three adjacent boxes is divisible by 3.

We can divide the boxes into three groups as follows:

Group 1: Boxes {1, 4, 7}

Group 2: Boxes {2, 5, 8}

Group 3: Boxes {3, 6, 9}

For any three boxes in a group, the sum of their contents must be divisible by 3. We can place any multiple of 3 in the middle box of each group, and the other two boxes will have to be filled accordingly.

Step-by-step explanation:

For Group 1:

If we place 3 in the middle box, then the boxes 1 and 7 must be filled with numbers that add up to a multiple of 3. We can choose from the following pairs: {1, 2}, {1, 5}, {4, 2}, {4, 5}, {7, 2}, {7, 5}. This gives us 6 possible ways to fill the boxes in Group 1.

If we place 6 in the middle box, then the boxes 1 and 7 must be filled with numbers that add up to a multiple of 3. We can choose from the following pairs: {1, 5}, {1, 8}, {4, 5}, {4, 8}, {7, 5}, {7, 8}. This gives us another 6 possible ways to fill the boxes in Group 1.

For Group 2:

If we place 3 in the middle box, then the boxes 2 and 8 must be filled with numbers that add up to a multiple of 3. We can choose from the following pairs: {1, 2}, {1, 5}, {4, 2}, {4, 5}, {7, 2}, {7, 5}. This gives us 6 possible ways to fill the boxes in Group 2.

If we place 6 in the middle box, then the boxes 2 and 8 must be filled with numbers that add up to a multiple of 3. We can choose from the following pairs: {1, 8}, {1, 5}, {4, 8}, {4, 5}, {7, 8}, {7, 5}. This gives us another 6 possible ways to fill the boxes in Group 2.

For Group 3:

If we place 3 in the middle box, then the boxes 3 and 9 must be filled with numbers that add up to a multiple of 3. We can choose from the following pairs: {2, 9}, {2, 6}, {5, 9}, {5, 6}, {8, 9}, {8, 6}. This gives us 6 possible ways to fill the boxes in Group 3.

If we place 6 in the middle box, then the boxes 3 and 9 must be filled with numbers that add up to a multiple of 3. We can choose from the following pairs: {2, 6}, {2, 3}, {5, 6}, {5, 3}, {8, 6}, {8, 3}. This gives us another 6 possible ways to fill the boxes in Group 3.

Therefore, the total number of ways to fill the boxes is:

6 x 6 x 6 x 6 = 1296.

Thus Bian can write the integers 1 to 9 in these ways.

hope it helps...

10. Use the poster order table to find the buying of a poster order of N15.=

Answers

The total cost of buying a postal order of N15 would be N15.50.

How to solve

To calculate the cost of buying a postal order of N365, we need to determine the commission associated with the value of N365 in the postal order table.

Since N365 is between N100 and N50, the commission for this amount would be N5.50.

Therefore, the total cost of buying a postal order of N365 would be N365 + N5.50 = N370.50.

To find the cost of buying a postal order of N15, we look at the postal order table and find that the commission associated with N15 is 50k.

Therefore, the total cost of buying a postal order of N15 would be N15 + 50k = N15.50.

Carlo is shown the results of two surveys about the preferred practice day of all players in a soccer league. The surveys are based on two different samples, and the results are very different. What information about the surveys might help Carlo decide which result is likely to be more accurate?

Please help, I really need to turn it in.

Answers

Carlo should consider the sample size, sampling method, response rate, and sampling frame when determining which survey result is likely to be more accurate. By investigating these factors, Carlo can make an informed decision as to which survey result is likely to be more accurate.

What is sample size?

Sample size is the number of participants or observations in a given study or experiment. It is an important factor in determining the validity and accuracy of the results. Large sample sizes are typically needed for experiments that involve multiple variables and for research with a small population. Sample size also affects the power of a test, which is the probability of correctly rejecting the null hypothesis.

In order to determine which survey result is more accurate, Carlo should first consider the sample size of each survey. If the sample size of one survey is significantly larger than the other, it is likely to be more accurate. Additionally, Carlo should consider the sampling method used in each survey. If one survey used a random sampling method while the other was not, then the random sample is more likely to be more representative of the entire population of players in the soccer league. Carlo should also consider the response rate for each survey, as surveys with higher response rates tend to be more accurate. Finally, Carlo should investigate the sampling frame used in each survey. If one survey used a sampling frame that was more representative of the population than the other, then it is likely to be more accurate.

Find the linear function with the following properties.

f(−3)=−12
f(−7)=4

Answers

Answer:

To find the linear function with the given properties, we need to determine the slope and y-intercept of the function.

We can use the slope-intercept form of a linear function, which is:

y = mx + b

where m is the slope and b is the y-intercept.

First, we can find the slope using the two given points:

slope = (y2 - y1) / (x2 - x1)

slope = (4 - (-12)) / (-7 - (-3))

slope = 16 / (-4)

slope = -4

Now that we have the slope, we can use one of the given points to find the y-intercept. Let's use the point (-3, -12):

y = mx + b

-12 = (-4)(-3) + b

-12 = 12 + b

b = -24

Therefore, the linear function that satisfies the given properties is:

f(x) = -4x - 24

Answer:

f(x) = -4x - 24

Step by step Explanation:

To find the linear function f(x) with the given properties, we can use the point-slope form of a linear equation:

y - y1 = m(x - x1)

where m is the slope of the line and (x1, y1) is a point on the line.

Using the two given points, we can find the slope of the line:

m = (y2 - y1) / (x2 - x1)

m = (4 - (-12)) / (-7 - (-3))

m = 16 / (-4)

m = -4

Now we have the slope of the line, and we can use one of the given points to find the y-intercept:

f(x1) = y1

f(-3) = -12

So when x = -3, y = -12. We can use this point to find the y-intercept:

y - y1 = m(x - x1)

y - (-12) = -4(x - (-3))

y + 12 = -4(x + 3)

y = -4x - 24

Therefore, the linear function f(x) that satisfies the given properties is:

f(x) = -4x - 24

A firm’s profit increased from 2020 to 2021 by 20%, but it decreased by 17% from
2021 to 2022. Which of the years 2020 and 2022 had the higher profit

Answers

Answer:

Step-by-step explanation:

Let the profit in 2020 be P.

The profit in 2021 would then be 1.20P (20% increase).

The profit in 2022 would be 0.83(1.20P) = 0.996P (17% decrease from 2021).

We can see that the profit in 2020 was P, while the profit in 2022 was less than P (0.996P).

Therefore, the higher profit was in 2020.

The solution is, the higher profit was in 2020.

What is percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

Let the profit in 2020 be P.

The profit in 2021 would then be 1.20P (20% increase).

The profit in 2022 would be 0.83(1.20P) = 0.996P (17% decrease from 2021).

We can see that the profit in 2020 was P, while the profit in 2022 was less than P (0.996P).

Therefore, the higher profit was in 2020.

The graph of y= h (x) is shown. Draw the graph of y = - h (x) - 4

Answers

Answer:

See graph

Step-by-step explanation:

The transformation is as follows

The transformation of h(x) to -h(x) - 4 is a combination of two transformations

1. A reflection around the x -axis. Every point(x, y) in h(x) becomes (x', y') where x' = x and y' = -y so (x, y) → (x, -y)

2. A translation of each reflected point 4 units down; x value does not change but y values are shifted down so the new y is y'-4 = -y -4

The result of both transformations is:
every coordinate (x, y) in h(x) will be transformed to (x, -y -4)

Seeing as the graph consists of two straight lines meeting at the origin, all we need to do is take any 3 points in h(x), find the transformed coordinates and connect them with straight ilnes

h(x0              -h(X) - 4

(-2, 4)    ⇒      (-2, -4-4) = (-2, -8)

(0, 0 )   ⇒       (0, -0 - 4) = (0, -4)

A large cylindrical can of juice has a diameter of 12 inches and a height of 15 inches. A small cylindrical glass has a diameter of 3 inches and a height of 3 inches. How many full glasses of juice can be poured from the large can of juice?

Answers

240 full glasses of juice can be poured from the large can of juice.

Calculating the volume of the large can of juice and the volume of the tiny glass is necessary to answer this problem. The volume of the can must then be divided by the volume of the glass to determine how many glasses can be filled.

The formula V = r2h, where r is the radius and h is the height, determines the volume of a cylinder.

The radius for the large juice can is equal to half the diameter, or r = 6 inches. It is 15 inches tall. Hence, the huge can's volume is as follows:

V large is equal to (1620)(6)2(15) cubic inches.

The radius for the little glass is equal to half its diameter, or 1.5 inches. It is 3 inches tall. Hence, the little glass's volume is as follows:

V small is equal to 1.5 x 2 x 3 or 6.75 cubic inches.

We divide the volume of the large can by the volume of the tiny glass to determine how many glasses can be filled:

V large/V small is equal to (1620)/(6.75), or 240.

As a result, the enormous can of juice can be used to fill 240 glasses to the brim.

The time to reach 125 feet is 1.3 seconds, the time to reach a maximum height of 147.52 ft is 2.5 seconds

How to determine the time to reach 125 feet

From the question, we have the following parameters that can be used in our computation:

h(t) = -16t^2 + 79t + 50

To do this, we set h(t) = 125

So, we have

-16t^2 + 79t + 50 = 125

Using a graphing tool, we have

t = 1.3

So, the time taken is 1.3 seconds

The maximum height and the time to reach this height

We have

h(t) = -16t^2 + 79t + 50

Differentiate and set to 0

-32t + 79 = 0

So, we have

32t = 79

This gives

t = 2.46875

t = 2.5

Next, we have

h(2.46875) = -16 * 2.46875^2 + 79 * 2.46875 + 50

Evaluate

h(2.46875) = 147.52

The commercial message that need to be run on every medium to maximize the audience is x = 15, y = 7 and z = 12.

Linear programming: What is it?

A mathematical method called linear programming is used to maximise a linear objective function under the restrictions of linear equality and inequality. Finding choice variable values that maximise or decrease the objective function while meeting the limitations is required.

Let us suppose the number of advertisement run on television = x.

Let us suppose the number of advertisement run on radio = y.

Let us suppose the number of advertisement run on online = z.

Then,

140,000x + 18,000y + 30,000z

The constraints on the ads run on are as follws:

1,500x + 200y + 550z <= 24,100 (budget constraint)

x <= 15 (television usage limit)

y <= 19 (radio usage limit)

z <= 12 (online usage limit)

y <= 0.45(x+y+z) (radio usage limit as a percentage of total usage)

x >= 0.15(x+y+z)

Using the linear programming model we have:

x = 15, y = 7 and z = 12.

Substitute the value of x, y, and z:

140,000(15) + 18,000(7) + 30,000(12) = 2,910,000

5. When will the rock be 125 feet above the beach?
b. What is the maximum height reached by the rock and how many seconds did it take for the rock
to reach that height?

Answers

The height of the rock is described by the quadratic equation:

h = -16t² + 79t + 50.

a. The rock will be 125 feet above the beach for approximately 3.66 and 1.28 seconds.

b. The rock will reach its maximum height in about 2.5 seconds, reaching a height of around 147.5 feet.

A quadratic equation is what?

An equation of the form f(x) = ax² + bx + c, where a 0 and a, b, and c are numbers, is a quadratic equation.

a. The following is how the rocket's height function is presented:

h(t) = -16·t² + 79·t + 50

The time at which the height is 125 feet is as follows:

h(t) = 125 feet

h(t) = 125 = -16·t² + 79·t + 50

-16·t² + 79·t + 50 - 125 = 125 - 125 = 0

-16·t² + 79·t - 75 = 0

The quadratic formula indicates:

t = (-79 ± √(79² - 4 × (-16) ×(-75)))/(2 × (-16)) = (79 ± √(1441))/32

t = (79 ± √(1441))/32

t = (79 + √(1441))/32 ≈ 3.66

t = (79 - √(1441))/32 ≈ 1.28

Therefore, the times at which the height of the rock is 125 feet above the beach are t ≈ 3.66 seconds, and t ≈ 1.28 seconds.

b.The formula for determining the input value at the maximum value of a quadratic function, which is: at the maximum height, x = -b/2a, can be used to determine the time at which the rock is at the maximum height.

Consequently, we obtain at the highest height;

t = -79/(2 (-16)) = 2.46875 is the time.

The rock climbs to its highest point in 2.46875 seconds, or 2.5 seconds.

Find the area of this composite shape. Include correct units. Show all your work.

Answers

The Area of Composite figure is 131cm² we can find it by dividing the figure in two parts.

What is Rectangle?

Rectangle is a plane which one side is long and other side is short and and all angle between these sides are 90° and opposite sides are parallel to each other.

We can divide this figure in two part Rectangle and Triangle.

The Rectangle having length = 10 cm and breadth = 5 cm.

Whereas, Triangle have sides having length 6cm (Base) and 3 cm (Perpendicular).

[tex]Area\ of\ Rectangle = Length (l) * Breadth (b)[/tex]

= 10 x 5 cm²

= 50 cm².

[tex]Area\ of\ Triangle =\frac{1}{2} *b*h[/tex]

For this we have to find third side,

[tex]Third\ Side = \sqrt{(First\ Side)^{2} +(Second\ Side)^{2} }[/tex] ( Using Pythagoras Theorem)

[tex]Third\ Side = \sqrt{(6)^{2} +(3)^{2} }[/tex]

Third Side = 6.7 cm

[tex]s= \frac{a + b + c}{2}[/tex] , where a, b, c are three sides

[tex]= \frac{6.7 + 6 +3}{2}[/tex]

= 7.85 cm.

Now we use Heron's formula to find the area of triangle,

Area of Triangle = [tex]\sqrt{s\ (s-a)\ (s-b)(\ s-c)}[/tex][tex]=\sqrt{7.85\ (7.85-6.7)\ (7.85-6)\ (7.86-3)}[/tex]

= 81 cm²

So the Area of Composite figure = (50 + 81) cm²

= 131 cm²

Find the equation of the ellipse, centre and directrices given that the end points of the major axis are (4,1) and (8,1) and the eccentricity is 1/3

Answers

The equation of the ellipse is (x - 6)² / 4 + (y - 1)² / (16/9) = 1, the center is (6,1), and the directrices are x = 0 and x = 12.

How to explain the equation

The center of the ellipse is the midpoint of the major axis. The midpoint of the line segment connecting (4,1) and (8,1) is ((4+8)/2, (1+1)/2) = (6,1). Therefore, the center of the ellipse is (6,1).

The distance between the center and one of the vertices (say, (8,1)) is the length of the semi-major axis, a. This distance is (8-6) = 2. Therefore, the semi-major axis is a = 2.

The eccentricity, e, is given as 1/3.

The distance between the center and one of the foci, c, is related to the semi-major axis and eccentricity by the equation c = ae. Plugging in the values we know, we get c = (1/3)(2) = 2/3.

We can write the equation of the ellipse in standard form:

(x - 6)² / 2² + (y - 1)^2 / b² = 1

where b is the semi-minor axis. We can solve for b using the relationship between the semi-major axis, semi-minor axis, and eccentricity:

So the equation of the ellipse is:

(x - 6)² / 4 + (y - 1)² / (16/9) = 1

The directrices are located a distance of a² / c = (2²) / (2/3) = 6 units away from the center along the major axis. These are the lines x = 6 - 6 = 0 and x = 6 + 6 = 12.

Division - Answer in gallons and quarts.
12.) 3 ) 10 gallons 11 quarts
1 gal. = 4 quarts

Answers

The answer to this question is 4 Gallons and 1 quart or we can say 17 quarts.

What is Gallon?

The US Customary System defines a unit of liquid volume or capacity as 4 quarts (3.79 liters).

we have to find the value of 10 gallons and 11 quarts in gallons and quarters after dividing by 3.

As we know,

1 gallon = 4 quarts

10 gallons = [tex]10 * 4[/tex]=40 quarts

so 40 quarts + 11 quarts= 51quarts

It must be divided by 3 (According to the question we have to divide by 3 )

So, it becomes,

[tex]\frac{51}{3} =17[/tex]

Now we get 17 quarts.

And 17 quarts= 4 gallons and 1 quarts

Let C be a unit circle centred at the origin, evaluate the complex integral of zdz/((z-a)^2) when; a<1 and a>1​

Answers

The complex integral of [tex]\frac{zdz}{(z-a)^2}[/tex] over the unit circle C is [tex]\frac{-4\pi i}{a}[/tex] if a < 1, and 0 if a > 1.

Evaluating the complex integral

From the question, we are to evaluate the given complex integral when a <1 and a > 1

We can evaluate the complex integral of [tex]\frac{zdz}{(z-a)^2}[/tex] over the unit circle C using the residue theorem. Since the function has a pole of order 2 at z = a, we need to compute the residue of the function at that point.

If a < 1, then the point a is inside the unit circle C. To compute the residue at z = a, we can expand the function in a Laurent series centered at z = a:

[tex]\frac{zdz}{(z-a)^2}= (\frac{1}{(z-a)})^2 d(z-a)[/tex]

= (1/(z-a))^2 dz - (2/(z-a))^1 da + ...

[tex](\frac{1}{(z-a)})^2dz -(\frac{2}{(z-a)})^1 da + ...[/tex] (Laurent series expansion)

The residue of the function at z = a is given by the coefficient of the [tex](z-a)^{-1}[/tex] term in this expansion, which is:

[tex]Res[z=z0] \frac{z dz}{(z-a)^2} = \frac{-2}{(a - 0)^1} = \frac{-2}{a}[/tex]

Therefore, by the residue theorem, the value of the integral is given by:

[tex]\oint \frac{c zdz}{(z-a)^2} = 2\pi i \times \frac{-2}{a} = \frac{-4\pi i}{a}[/tex]

If a > 1, then the point a is outside the unit circle C. Since the function is holomorphic on and inside the unit circle, it has no singularities inside C and the integral is zero:

[tex]\oint \frac{c zdz}{(z-a)^2} = 0[/tex]

Hence, the complex integral is [tex]\frac{-4\pi i}{a}[/tex] when a < 1, and 0 if a > 1.
