f the null space of a 7 ×6 matrix a is 5 -dimensional, what is the dimension of the column space of a?

Answer:

Step-by-step explanation:

We know that the form of line passing through point (x₀ , y₀) and having slope m is :

 y - y₀ = m(x - x₀)

Here the line passes through the point (5 , -3)

⇒ x₀ = -2 and y₀ = -5

Given : Slope(m) = -8

Substituting all the values in the standard form, We get :

Equation of the line : y + 3 = -8(x - 5)

the relationship between test scores and the student-teacher ratio can be modeled as a linear function: The right choice is D) lessen test scores by 4.56 for each school locale.

In view of the data in the inquiry, the relationship between test scores and the understudy educator proportion can be numerically composed as follows:

x = 698.9 - 2.28y .................... (1)

Where,

x = test scores

y = understudy educator proportion

The slant of (- 2.28) shows the sum by which x will change at whatever point there is an adjustment of y.

Hence, when there is a reduction in the understudy educator proportion by 2 (for example y = 2), we will have:

Change in x = - 2.28 * 2 = - 4.56

The negative sign thusly shows that the test scores will decrease by 4.56 for each school area. Accordingly, the right choice is D) lessen test scores by 4.56 for each school locale.

A decrease in the student teacher ratio by 2 will: A) reduce test scores by 2.28 on average) result in a test score of 698.9C) reduce test scores by 2.56 on average) reduce test scores by 4.56 for every school district.

Answer:

C. (x - 6)(x - 8)

Step-by-step explanation:

To factorize the expression x^2 - 14x + 48, we need to find two binomial factors whose product is equal to the given expression. We are looking for two numbers that multiply to give 48 and add up to -14.

The possible factor pairs of 48 are:

1 * 48

2 * 24

3 * 16

4 * 12

6 * 8

Among these pairs, the only pair whose sum is -14 is 6 and 8.

So, the factorization of the expression x^2 - 14x + 48 is:

(x - 6)(x - 8)

Answer: C

Step-by-step explanation:

To factorize the equation x^2 - 14x + 48, we need to find two binomial factors that, when multiplied together, result in the given quadratic expression.

To factorize the quadratic equation, we look for two numbers that multiply to give the constant term (48) and add up to give the coefficient of the linear term (-14). In this case, the numbers are -6 and -8 since (-6) * (-8) = 48 and (-6) + (-8) = -14.

Now, we can rewrite the quadratic expression as follows:

x^2 - 14x + 48 = (x - 6)(x - 8)

Therefore, the factored form of the equation x^2 - 14x + 48 is (x - 6)(x - 8).

The answer is 3/10

Explanation:

= 3/4 x 2/5

= 3/4 x 2/5

= 3/2 x 1/5

= 3 x 1 / 2 x 5

= 3 / 2 x 5

= 3/10

Answer:

-2                                        

Step-by-step explanation:

Hey there!!

if we evaluate the expression it will look like :

3x + 14 = 8

and if we solve it:

3x+14=8

Step 1: Subtract 14 from both sides.

3x+14−14=8−14

3x=−6

Step 2: Divide both sides by 3.

3x/3 = -6/3

x= −2

The standard form of polynomial is to write the polynomial so that the term with the highest power of the variable comes first, followed by the other terms in order of descending powers of the variable.

A polynomial in standard form requires that the polynomial be written in descending order of exponents. Polynomials are written in standard form for ease of computation. A polynomial is in its canonical form when it is expressed with the highest order term first, followed by the higher order terms, and so on. For example: 14x⁴ - 5x³ - 11x² - 11x + 8. You can see that in this standard form polynomial, the exponents are ordered in descending powers. These algebraic equations are called polynomials. Procedure for writing polynomials in standard form:

The normal form polynomial of degree 'n' is : aₙxⁿ + aₙ₋₁ x⁽ⁿ⁻¹⁾ + ... + a₁ x + a₀

Let us assume a polynomial, p(x) = x² + 8x - 9 + 7x³ - 6x + x⁴ , using the above steps we can write the standard form of p(x).

If a party gaining 25% of vote out of 100 seats in a pure proportional representation system would mean that the party got 25 seats.

We can compute it as,

100 × 25% = 25

A group of electoral systems used to choose candidates in multi-member electorates are referred to as proportional representation (PR). PR allows for the proportional representation of parties, organisations, and independent candidates in the selection of members of Parliament. Systems that use proportional representation have some advantages over the winner-takes-all principle.

The essence of such systems is that they provide mixed, balanced representation that reflects how votes are cast and that all votes cast, or nearly all votes cast, contribute to the outcome and are genuinely used to help elect someone. Due to the fact that seats are distributed based on the number of votes each party receives, few votes are "wasted," more parties can win seats in the legislature, and justice is prioritised.

Solve the differential  equations (a) & (b) and plot three solution curves.

let's start by understanding the concepts of slope fields and solution curves. A slope field is a graphical representation of the solutions to a differential equation. It shows a vector field, or a graph of the direction and magnitude of the solutions, at any given point. Solution curves are the individual solutions of the differential equation that can be seen on the slope field.

To find equilibrium solutions and classify them as stable, semistable or unstable for the given differential equations, you need to solve the equations for the given initial conditions and then plot the solutions on the slope field.

For the first equation (a), y' = y(y+1), you need to solve the equation and plot three solution curves on the slope field. Then you should find the equilibrium solutions and classify them as stable, semistable, or unstable.

Similarly, for the second equation (b), y'= 2t + y, you need to solve the equation  and plot three solution curves on the slope field. Then you should find the equilibrium solutions and classify them as stable, semistable, or unstable.

Correct question:

What type of statistical learning do all data examples supervised or unsupervised?

Answer:

55 performances

Step-by-step explanation:

The first equation will be the total cost. The total cost has $88,000 already and then $5,900 is added with each performance. So the equation would be 88,000+5,900x because x will represent the number of performances.

y = 88,000 + 5,900x

The next equation will be how much the performances earn. If they earn $7,500 with each performance then the equation will be 7,500x, with x representing the number of performances

y = 7,500x

Now set the equations equal to each other and solve for x

7,500x = 88,000 + 5,900x

1,600x = 88,000

x = 55

They need to have 55 performances for the cost and the revenue to break even.

usage patterns are a variable used in market segmentation.

Step-by-step explanation:

Usage patterns are a variable used in behavioral segmentation.

Behavioral segmentation is a marketing strategy that divides a market into different segments based on consumer behavior, specifically their patterns of product usage, buying habits, and decision-making processes. This segmentation approach recognizes that customers with similar behavioral characteristics are likely to exhibit similar preferences and respond in a similar manner to marketing initiatives.

Usage patterns, as a variable, help marketers understand and classify customers based on how they interact with a product or service. This can include factors such as the frequency of product usage, the amount of product used, the timing of purchases, brand loyalty, product benefits sought, and other behavioral indicators.

By analyzing usage patterns, marketers can identify distinct segments within their target market and tailor marketing strategies to meet the unique needs and preferences of each segment. This enables companies to develop more targeted marketing campaigns, optimize product offerings, improve customer satisfaction, and drive customer loyalty.

Overall, behavioral segmentation, including the consideration of usage patterns, allows companies to better understand and connect with their customers by aligning their marketing efforts with specific behaviors and motivations.

A cargo ship left port A and is headed across the ocean to shipping port B. After one month, the ship stopped at a refueling station along a path described by a vector with components 〈14, 23〉. The characteristics of the vector representing the path of the ship are "components: 〈7, 11.5〉, magnitude: 13.46".

After another month, on the same path, the ship reached port B, twice the distance from port A as the fueling station. The distance between A and the fueling station is x units.

Then, the distance between B and the fueling station is 2x units.AB = 2x units. The fueling station is located at 〈14, 23〉. And A is located at (0, 0)Now we can calculate the distance between A and the fueling station using the distance formula.= √[(14 - 0)² + (23 - 0)²]= √(196 + 529)= √725= 26.92 approx.

After another month, on the same path, the ship reached port B, twice the distance from port A as the fueling station. The distance between A and the fueling station is 26.92 units. Then, the distance between B and the fueling station is 2 × 26.92 = 53.85 units.

Now we can calculate the vector AB using the below formula: AB = OB - OAwhere, OA = (0, 0)OB = (7, 11.5)

So, AB = OB - OA= (7, 11.5) - (0, 0)= (7, 11.5)

Magnitude of vector AB = √(7² + 11.5²)= √(49 + 132.25)= √181.25= 13.46 approx.

So, the correct answer is "components: 〈7, 11.5〉, magnitude: 13.46".
