Answer: Simple regression

Step-by-step explanation:

A regression analysis that involves one independent variable and one dependent variable is called the simple regression.

The Simple Regression Analysis shows the relationship that exist between the dependent variable which is the value that's to be predicted and the independent variable. The dependent variable depends on the independent variable

Find u*v, if u=13j and v=i+3j

Alexxx [7]

Answer:

u * v = 39 ⇒ 2nd answer

Step-by-step explanation:

* Lets explain how to solve the problem

- u and v are two vectors

- u * v means the scalar product of the two vectors

- The scalar product is a way of multiplying vectors

- The result of a scalar product is always a number not a vector

- Ex: If u = ai + bj ⇒ <a , b> and v = ci + dj ⇒ <c , d> then the scalar

product of them is ac + bd where ac + bd is a number

* Lets solve the problem

∵ Vector u = 13j ⇒ <0 , 13>

∵ Vector v = i + 3j ⇒ <1 , 3>

- Lets find the scalar product

∴ u * v = (0)(1) + (13)(3)

∴ u * v = 0 + 39

∴ u * v = 39

Eight less than four times a number is less than 56. What are the possible<br> Values of that number

Ivan

Answer:

Step-by-step explanation:

If you would like to write the following in the math expression, you can do this using these steps:

a number ... n

eight less than four times a number ... 4 * n - 8

is less than 56 ... < 56

4 * n - 8 < 56

4 * n < 56 + 8

4 * n < 64 /4

n < 64 / 4

n < 16

The possible values of that number are less than 16.

PLEASE HELP!

The graph first represents the provided piecewise function option first is correct.

<h3>What is a piecewise function?</h3>

The graph of a piecewise function contains numerous curve components. It signifies that it has a plethora of definitions based on the value of the input. In other words, a piecewise function behaves differently depending on the input.

We have a piecewise function shown in the picture.

$\rm y=\left\{x\le-2:\sqrt{-x-2}\right\}$

$\rm y=\left\{-2 < x < 1:\dfrac{x}{x^{2}+x-2}\right\}$

$\rm y=\left\{x\ge1:\log_{2}\left(x+1\right)\right\}$

After plotting all the pieces of a function on the coordinate plane we will get a graph the same as shown in the first option.

Thus, the graph first represents the provided piecewise function option first is correct.
