The mixed integer would be 2 3/4.

A mixed integer is a number that includes both a whole number and a fraction. For example, 2 1/2 is a mixed integer because it includes the whole number 2 and the fraction 1/2.

To rewrite a fraction as a mixed integer, you need to divide the numerator (the top number) by the denominator (the bottom number) and find the quotient and remainder. The quotient will be the whole number part of the mixed integer and the remainder will be the numerator of the fraction part. The denominator will stay the same.

For example, if you have the fraction 11/4, you can divide 11 by 4 to get a quotient of 2 and a remainder of 3. So the mixed integer would be 2 3/4.

Here are the steps to rewrite a fraction as a mixed integer:
1. Divide the numerator by the denominator.
2. Write the quotient as the whole number part of the mixed integer.
3. Write the remainder as the numerator of the fraction part of the mixed integer.
4. Keep the denominator the same.
5. Simplify the fraction if necessary.

The required fill-in-the-blanks are "same" and "line segments".

A linear relationship is a connection that takes the shape of a straight line on a graph between two distinct variables - x and y. When displaying a linear connection using an equation, the value of y is derived from the value of x, indicating their relationship.

Sometimes, the relationship between the variables doesn't stay the "same". This type of relation is called a piecewise linear relationship.

The graph of a piecewise linear relationship is made of non-overlapping "line segments", like this one.

Answer:

Let's start by using variables to represent the number of rows containing 20 vines and 25 vines. Let:

x be the number of rows containing 20 vines

3x be the number of rows containing 25 vines (since there are 3 times as many rows containing 25 vines as there are rows containing 20 vines)

We know that Sarah plants a total of 760 vines, and that each row contains either 20 vines or 25 vines. Therefore, we can write an equation based on the total number of vines:

20x + 25(3x) = 760

Simplifying and solving for x:

20x + 75x = 760

95x = 760

x = 8

So there are 8 rows containing 20 vines, and 3 times as many rows containing 25 vines, or 3(8) = 24 rows containing 25 vines.

Therefore, Sarah planted 8 rows with 20 vines and 24 rows with 25 vines.

Step-by-step explanation:

Inverse of a Function.

To find the inverse of the function f(x) = √(x+7), we need to interchange the roles of x and y and solve for y.

Let y = f(x) = √(x+7)

To find the inverse, we need to solve for x in terms of y.

Step 1: Square both sides of the equation to eliminate the square root:

y^2 = x + 7

Step 2: Solve for x:

x = y^2 - 7

So the inverse of the function f(x) is:

f^(-1)(y) = y^2 - 7

We can also express the inverse in terms of x:

f^(-1)(x) = x^2 - 7

Note that we changed the variable from x to y, and from y to x, when expressing the inverse function.

A function can be defined as a relation between a set of inputs having one output each. In other words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and co-domain (range). A function is generally denoted by f(x) where x is the input.

here, we have,

The general mathematical representation of a function is y = f(x).

f(x)=x²- 5x+7

g(x)=3x² + 4x - 2

so, we get,

(f- g)(x) = x²- 5x+7 - (3x² + 4x - 2)

(f- g)(x) = x²- 5x+7 - 3x² - 4x + 2

(f- g)(x) = -2x² - 9x + 9

(g-f)(x) = 3x² + 4x - 2 - (x²- 5x+7)

(g-f)(x) = 3x² + 4x - 2 - x² + 5x - 7

(g-f)(x) = 2x² + 9x - 9

Using composition function , the price of the computer after both discounts are applied is 0.7x - 140.

To find the price of the computer after both discounts are applied, we can use composition function . Specifically, we can find the composition of f and g, denoted as f(g(x)) or (f o g)(x). This will give us the price of the computer after both discounts are applied.

To find f(g(x)), we can substitute the expression for g(x) into the function f(x):

f(g(x)) = f(0.7x) = (0.7x) - 200

So the price of the computer after both discounts are applied is (0.7x) - 200.

Alternatively, we could find the composition of g and f, denoted as g(f(x)) or (g o f)(x). This will give us the same result, since the order of the discounts does not matter.

To find g(f(x)), we can substitute the expression for f(x) into the function g(x):

g(f(x)) = g(x-200) = 0.7(x-200) = 0.7x - 140


Either way, we can see that the price of the computer after both discounts are applied is a function of the original price x, and can be represented by the composition of the functions f and g.

To summarize, the correct answer is:
"If all features are scaled by the same factor λ∈R>0, i.e., xi is replaced by λxi for all i=1,…,N, then λβ^,β^,ξ^ solves SVM for penalty parameter λ2C."

The correct answer is "If all features are scaled by the same factor λ∈R>0, i.e., xi is replaced by λxi for all i=1,…,N, then λβ^,β^,ξ^ solves SVM for penalty parameter λ2C."

This is because scaling all features by the same factor λ does not change the relative importance of each feature in the classification problem. Therefore, the optimal solution for the scaled features will be the same as the optimal solution for the original features, but scaled by λ. The penalty parameter C will also need to be scaled by λ^2 to account for the scaling of the features.

To summarize, the correct answer is:

(a) The probability that X = n is 2^n-1 / 2^N - 1.

(b) ɸ(t) = E[2^tx] = ∑_{n=1}^N 2^tx P(X=n) = ∑_{n=1}^N 2^tx (2^n-1 / 2^N - 1) = (2^t / 2^N - 1) ∑_{n=1}^N 2^(n-1)t = (2^t / 2^N - 1) (2^Nt - 1) / (2^t - 1) = 2^Nt / (2^N - 1)

(c) The probability that X = n and Y = m is 2^(n-m-1) / 2^N - 1.

(d) This is the same as finding the probability that the difference between the maximum and minimum elements of a subset of {1,...,N} is k. If k = 0, then the only subsets with maximum and minimum elements differing by k are the single-element subsets, so P(W=k) = N / 2^N - 1. If k > 0, then there are (N-k) choices for the minimum element m and 2^(k-1) subsets of {m+1,...,m+k-1}, so P(W=k) = (N-k) 2^(k-1) / 2^N - 1.

To find the probability mass function of X, we need to find the probability that X = n for each n ∈ {1,...,N}. This is the same as finding the probability that the maximum element of a subset of {1,...,N} is n. There are 2^n-1 subsets of {1,...,n-1}, and each of these subsets can be combined with n to form a subset of {1,...,N} with maximum element n. Therefore, the probability that X = n is 2^n-1 / 2^N - 1.

To find the value of ɸ(t) for any t ∈ R, we need to compute the expected value of 2^tx. Using the formula for expected value, we get:

ɸ(t) = E[2^tx] = ∑_{n=1}^N 2^tx P(X=n) = ∑_{n=1}^N 2^tx (2^n-1 / 2^N - 1) = (2^t / 2^N - 1) ∑_{n=1}^N 2^(n-1)t = (2^t / 2^N - 1) (2^Nt - 1) / (2^t - 1) = 2^Nt / (2^N - 1)

To find the joint probability mass function of (X,Y), we need to find the probability that X = n and Y = m for each n,m ∈ {1,...,N}. If n = m, then the only subset of {1,...,N} with maximum element n and minimum element m is {n}, so P(X=n, Y=m) = 1 / 2^N - 1. If n ≠ m, then there are 2^(n-m-1) subsets of {m+1,...,n-1}, and each of these subsets can be combined with m and n to form a subset of {1,...,N} with maximum element n and minimum element m. Therefore, the probability that X = n and Y = m is 2^(n-m-1) / 2^N - 1.

To find the probability mass function of W = X - Y, we need to find the probability that W = k for each k ∈ {0,...,N-1}. This is the same as finding the probability that the difference between the maximum and minimum elements of a subset of {1,...,N} is k. If k = 0, then the only subsets with maximum and minimum elements differing by k are the single-element subsets, so P(W=k) = N / 2^N - 1. If k > 0, then there are (N-k) choices for the minimum element m and 2^(k-1) subsets of {m+1,...,m+k-1}, so P(W=k) = (N-k) 2^(k-1) / 2^N - 1.

not completely sure but i think you times the x and y numbers then draw a graph of the units

Answer:

Step-by-step explanation:

It seems like the problem is asking about a sequence of shapes rather than a sequence of matches, so I will assume that the correct information for the problem is:

Number of shapes:

n=1 n=2 n=3

m-4 m=7 m+2

i) Sequence table for the first six patterns:

Pattern number Number of shapes

1                               m-4

2                               m

3                               m+2

4                               m+6

5                               m+10

6                               m+14

ii) Formula for the number of shapes in terms of the pattern number:

From the table, we can see that the number of shapes used in each pattern is increasing by a constant amount of 4. Therefore, we can write the formula as:

Number of shapes = (pattern number - 1) * 4 + m

where m is the number of shapes in the first pattern.

iii) Number of shapes used in the 300th pattern:

To find the number of shapes used in the 300th pattern, we can use the formula and substitute pattern number = 300:

Number of shapes = (300 - 1) * 4 + m

Since we don't know the value of m, we can't determine the exact number of shapes. However, we do know that the number of shapes in the first pattern is either m-4, m, or m+2, depending on the value of m. If we assume the smallest possible value of m, which is 1 (since the number of shapes can't be negative), then the number of shapes in the 300th pattern would be:

Number of shapes = (300 - 1) * 4 + 1-4 = 1195

Therefore, if m = 1, then the number of shapes used in the 300th pattern is 1195. However, if m is greater than 1, then the number of shapes in the 300th pattern would be higher.

You forgot the +- part when taking the square roots

Step-by-step explanation:

5 x^2  = -2

x^2 = -2/5

x = +- sqrt ( -2/5)       <==== note sqrt(-2/5)   NOT  sqrt (-2) / 5

x = ± i sqrt(2/5)

x^2 = 8

x = ±sqrt 8

x = ±2 sqrt (2)

To find the zeros, set the function equal to 0.  In other words, solve f(x)=0.

             f(x) = 0

x^2 +6x + 8 = 0

 (x+4)(x +2) = 0

x = -4 and x = -2

The vertex will happen when x = -b/2a:

    [tex]x=\dfrac{-6}{2(1)} = -3[/tex]
Then use this x-value of –3 to find the y-value of the vertex:

   y = (-3)^2 + 6(-3) + 8 = 9-18+8 = -1

The vertex is (-3,-1).

Side note: The x-value of the vertex can also be found by finding the average of the two zeros:

    (-4 + (-2)) / 2 = -6/2 = -3

The coordinates of the image of EB are (0, -1) and (-6, 18).

Dilation is a process for creating similar figures by changing the dimensions.

The center of dilation is given as (3, -1) and the scale factor is 3.

The distance between the center of dilation and point E is:

d = √((3-2)² + (-1-(-1))²) = 1

The distance between the center of dilation and point B is:

d = √((3-0)² + (-1-5)²) = sqrt(65)

To find the new distance, we multiply the distance by the scale factor:

For point E: 3 × 1 = 3

For point B: 3 × √(65)

Now, we can find the coordinates of the image:

For point E:

x = 3 × (2 - 3) + 3 = -3 + 3 = 0

y = 3 × (-1 -(-1)) -1 = 0 - 1 = -1

So the image of E is (0, -1).

For point B:

x = 3 × (0 - 3) + 3 = -9 + 3 = -6

y = 3 × (5 -(-1)) -1 = 18

So the image of B is (-6, 18).

Therefore, the coordinates of the image of EB are (0, -1) and (-6, 18).
