Answer:

Step-by-step explanation:

Last year

Ratio of the number of middle school students to number of high school students = 1 : 8

Total ratio = 9

Middle school = 1

High school = 8

Total students in the band = x

Middle school = 1/9x

High school = 8/9x

Total = 1/9x + 8/9x

This year

Ratio of the number of middle school students to number of high school students = 2 : 7

Total ratio = 9

Middle school = 2

High school = 7

Total students = x

Middle school = 2/9x

High school = 7/9x

Total = 2/9x + 7/9x

If there are 18 middle school students in the band this year

2/9x = 18

x = 18÷2/9

= 18 × 9/2

= 81

x = 81

Last year:

1/9x + 8/9x

= 1/9 * 81 + 8/9 * 81

= 9 + 72

= 81

This year

2/9x + 7/9x

2/9*81 + 7/9*81

= 18 + 63

=81

Change in middle school =this year - last year

= 18 - 9

= 9 (increase)

Change in high school = this year - last year

= 63 - 72

= -9 (decrease)

1/5 + 1/5 = 2/5

1/7 + 1/7 = 2/7

1/3 + 1/3 = 2/3

There are an infinite number of these fractions. They must be 1 and 1 in the numerator, and the denominator must be relatively prime  to 2. The examples I have picked are prime in the denominator, but the rule is not without many exceptions. For example

1/9 + 1/9 = 2/9

I don't think you can pick an even denominator because it will reduce when put with two.  Oh wait 2/18 + 2/18 = 4/18 = 2/9 But these could be reduced before adding. Still, it might count. It depends on who is marking the question.

What about an odd and even denominator?

1/9 + 1/18 = 3/18 = 1/6  There must be something that works, but I can't come up with an example.

3rd choice

Step-by-step explanation:

y = mx + b

Look at where the line crosses the y-axis. That is the y-intercept. It is 2, so b = 2, and you have

y = mx + 2

Now we need the slope, m.

Start at (0, 2). Go up 1 and right 2.

slope = m = rise/run = 1/2

Now you have

y = 1/2 x + 2

Answer: 3rd choice

Answer:

\(c)y=\frac{1}{2}x+2\)

Step-by-step explanation:

\(We\ know\ that,\\The\ equation\ of\ a\ graph\ is\ given\ by\ the\ formula:\\y=mx+b,\ where\ m\ is\ the\ slope\ of\ the\ graph,\ and\ b\ is\ the\ y-intercept;\\Here,\\First,\\Lets\ calculate\ the\ slope\ of\ the\ graph:\\We\ also\ know\ that,\\Slope(m)=\frac{rise}{run}=\frac{y_2-y_1}{x_2-x_1}\\Lets\ consider\ any\ two\ points\ which\ lie\ on\ the\ line:\\(2,3),(-2,1)\\Hence,\\The\ slope\ of\ the\ given\ line=\frac{1-3}{-2-2}=\frac{-2}{-4}=\frac{1}{2}\\Hence,\\m=\frac{1}{2}\\\)

\(Now,\\The\ y-intercept\ is\ the\ point\ at\ which\ the\ graph\ intersects\ the\ whole\ y-axis.\\Hence,\\Here,\\The\ line\ of\ the\ graph\ cuts\ the\ y-axis\ at\ (0,2).\\The\ y-intercept\ of\ the\ line=2\\Hence,\\The\ equation\ of\ the\ line:\\y=(\frac{1}{2})x+(+2)\\y=\frac{1}{2}x+2\)

The price range for the past week's common stock is $1.125.

To calculate the price range, we need to find the difference between the highest and lowest prices. The highest price is $62 and the lowest price is $60.875. So, the difference between them is:

$62 - $60.875 = $1.125

Therefore, the price range for the past week's common stock is $1.125.

The partial derivatives of the function \(F(x,y,z)=x^5z^4+sin(y^3z^ 4)-4=0\) are ∂x/∂z = \(-4x^5z^3\)   and ∂y/∂z = \(12y^2z^7cos(y^3z^4)\).

The given surface function is \(F(x, y, z) = x^5z^4 + sin(y^3z^4) - 4\).

To find the partial derivatives ∂x/∂z and ∂y/∂z, we need to differentiate the surface function F(x, y, z) with respect to z while treating x and y as constants.

Let's find the partial derivative ∂x/∂z:

To differentiate \(x^5z^4\) with respect to z, we treat x as a constant and apply the power rule for differentiation:

∂x/∂z = \(0 + 0 - 4x^5z^3 + 0 - 0\)

∂x/∂z = \(-4x^5z^3\)

Next, let's find the partial derivative ∂y/∂z:

To differentiate \(sin(y^3z^4)\) with respect to z, we treat y as a constant and apply the chain rule:

∂y/∂z  = \(0 + cos(y^3z^4) * (3y^2z^4) * (4z^3)\)

∂y/∂z = \(12y^2z^7cos(y^3z^4)\)

Therefore, the partial derivatives of the function \(F(x,y,z)=x^5z^4+sin(y^3z^ 4)-4=0\) are ∂x/∂z = \(-4x^5z^3\)   and ∂y/∂z = \(12y^2z^7cos(y^3z^4)\)

Step-by-step explanation:I am sorry if this doesn't help but I dont know the answer???

a) The angle between vectors A and B is approximately 154.68 degrees.To find the angles between the vectors A and B,

we can use the dot product formula and the fact that the dot product of two vectors A and B is given by:

A · B = |A| |B| cos(θ)

where |A| and |B| represent the magnitudes of vectors A and B, respectively, and θ is the angle between them.

Let's calculate the angles for each case:

(a) A = 2î − 7ĵ, B = -5î + 3ĵ:

Using the dot product formula:

A · B = (2)(-5) + (-7)(3) = -10 - 21 = -31

The magnitude of A:

|A| = √(2^2 + (-7)^2) = √(4 + 49) = √53

The magnitude of B:

|B| = √((-5)^2 + 3^2) = √(25 + 9) = √34

Now, we can calculate the angle θ using the formula:

-31 = (√53)(√34)cos(θ)

Simplifying:

cos(θ) = -31 / (√53)(√34)

Using inverse cosine (arccos) to find θ:

θ = arccos(-31 / (√53)(√34))

The angle between vectors A and B is approximately θ = 154.68 degrees.

(b) A = 6î + 4ĵ, B = 3î − 3ĵ:

Using the dot product formula:

A · B = (6)(3) + (4)(-3) = 18 - 12 = 6

The magnitude of A:

|A| = √(6^2 + 4^2) = √(36 + 16) = √52 = 2√13

The magnitude of B:

|B| = √(3^2 + (-3)^2) = √(9 + 9) = √18 = 3√2

Now, we can calculate the angle θ using the formula:

6 = (2√13)(3√2)cos(θ)

Simplifying:

cos(θ) = 6 / (2√13)(3√2) = 1 / (√13)(√2)

Using inverse cosine (arccos) to find θ:

θ = arccos(1 / (√13)(√2))

The angle between vectors A and B is approximately θ = 23.38 degrees.

(c) A = 7î + 5ĵ, B = 5î − 7ĵ:

Using the dot product formula:

A · B = (7)(5) + (5)(-7) = 35 - 35 = 0

The magnitude of A:

|A| = √(7^2 + 5^2) = √(49 + 25) = √74

The magnitude of B:

|B| = √(5^2 + (-7)^2) = √(25 + 49) = √74

Now, we can calculate the angle θ using the formula:

0 = (√74)(√74)cos(θ)

Since the dot product is zero, it indicates that the vectors are orthogonal (perpendicular) to each other. In this case, the angle between vectors A and B is θ = 90 degrees.

Therefore, for the given cases:

(a) The angle between vectors A and

B is approximately 154.68 degrees.

(b) The angle between vectors A and B is approximately 23.38 degrees.

(c) The angle between vectors A and B is 90 degrees.

Answer:

Step-by-step explanation:

To determine which option gives a better chance of winning, we need to calculate the expected number of A's and B's in the 1,000 draws and compare it to the conditions for winning in each option.

Let's calculate the expected number of A's and B's:

Number of A's in "ARABIA": 3

Number of B's in "ARABIA": 1

Total number of letters in "ARABIA": 6

Probability of drawing an A: 3/6 = 1/2

Probability of drawing a B: 1/6

Expected number of A's in 1,000 draws: (1/2) * 1,000 = 500

Expected number of B's in 1,000 draws: (1/6) * 1,000 = 166.67

Now let's analyze the conditions for winning in each option:

Option A: You win a dollar if the number of A's among the draws is 10 or more above the expected number (500 + 10 = 510 or more).

Option B: You win a dollar if the number of B's among the draws is 10 or more above the expected number (166.67 + 10 = 176.67 or more).

Comparing the two options:

Option A requires having 510 or more A's out of the 1,000 draws.

Option B requires having 176.67 or more B's out of the 1,000 draws.

Since it is not possible to have a fraction of a letter, the number of B's will always be an integer. Therefore, it is impossible to reach the condition for winning in option B, as there can't be 176.67 B's.

Therefore, the correct answer is:

(i) Option A gives a better chance of winning than option B.

There are 55 ways to form a train consisting of tank cars, boxcars, and flatcars by using concept of combinations.

If there are t tank cars, b boxcars, and f flatcars in the train yard, then the number of ways to form a train by selecting some of these cars is the same as the number of ways to distribute n = t + b + f identical objects into three distinct boxes, such that each box may receive any number of objects (including zero). The solution is given by the combination formula:

C(n + k - 1, k - 1)

where k is the number of boxes (in this case, k = 3). Therefore, the number of ways to form a train from t tank cars, b boxcars, and f flatcars is:

C(t + b + f + 3 - 1, 3 - 1) = C(t + b + f + 2, 2) = (t + b + f + 2)! / ((t + b + f)! * 2!)

There are 4 tank cars, 3 boxcars, and 2 flatcars in the train yard, then the number of ways to form a train is:

C(4 + 3 + 2 + 2, 2) = C(11, 2) = 55

The ratio of the volumes of the two similar pyramids with edges of ratio 5:7 is 125:343.

The volumes of two similar pyramids can be found using the ratio of their corresponding edge length.

Let's assume that the ratio of the edge length of the two similar pyramids is 5:7. This means that the base edge of the larger pyramid is 7x, and the base edge of the smaller pyramid is 5x.

The ratio of their corresponding volumes is equal to the cube of the ratio of their edges. This means that the volume of the larger pyramid is \((7x)^3\) and the volume of the smaller pyramid is (5x)^3.

So, the ratio of their volumes is:

The Volume ratio is: \((7x)^3 / (5x)^3 = (343/125) \times x^3 = 2.744 \times x^3\)

This means that the larger pyramid has a volume 2.744 times larger than the smaller pyramid.

In general, for two similar pyramids with corresponding edges of ratio a:b, the ratio of their volumes is (\(a^3 : b^3\)).

An alias cannot be used when a table is required to be joined to itself in a recursive query is false.

The majority of relational database management systems, if not all of them, include the SQL feature known as an alias (RDBMSs). Database administrators and other database users can use aliases to cut down on the amount of coding necessary for a query and to make it easier to understand. Additionally, the real names of database fields can be protected using aliasing as an obfuscation approach.

You can alias tables and columns in SQL. A correlation name is another term for a table alias. [1] For the duration of a SELECT query, a programmer can temporarily give a table or column a different name by using an alias. The column or table are not truly renamed when an alias is assigned.

If a model gives good results on the in-sample data but fails to be generally applicable to out-of-sample data, it is referred to as Overfitting.

Overfitting. Understanding Overfitting Overfitting is a situation where the data used for training is the "best".  So that if a test is carried out using different data it can reduce accuracy (results that are made are not as expected).  Overfitting can occur when some constraints are based on special properties that don't make a difference to the data.  Besides that, excessive duplication of minor data can also result in overfitting. To overcome the problem of Overfitting or Underfitting, there are several ways you can try:

• Double-check the validity of the data set.

• Use the resampling technique to estimate model accuracy.  Where later it will validate several times with different data comparisons until it finds optimal accuracy.
