Answer and Step-by-step explanation:

For this triangle, to find x, we will use the cosine trigonometric function.

cosine functions look like this:

$cos(\theta) = \frac{adjacent}{hypotenuse}$

(The weird looking symbol is called theta, and represents an angle measurement)

Plug in the values into the equation.

cos(42) = $\frac{x}{15}$

Multiply both sides by 15.

15(cos(42)) = x

Plug into a calculator.

11.1472 is the answer.

Answer:

Step-by-step explanation:

In this technique, if we have to factorise an expression like ax2+bx+c, we need to think of 2 numbers such that:

N1⋅N2=a⋅c=1⋅−12=−12

AND

N1+N2=b=−1

After trying out a few numbers we get N1=3 and N2=−4

3⋅−4=−12, and 3+(−4)=−1

x2−x−12=x2−4x+3x−12

x(x−4)+3(x−4)=0

(x+3)(x−4)=0

Now we equate the factors to zero.

x+3=0,x=−3

x−4=0,x=4

Answer:

<h3>"In a linear regression model, the variable that is being predicted or explained is known as _dependent variable It is denoted by y and is often referred to as the response variable".</h3>

Step-by-step explanation:

Given that "In a linear regression model, the variable that is being predicted or explained is known as dependent variable It is denoted by y and is often referred to as the response variable".

Because linear regression models for variables are used to explain or predict the relationship between two variables.
The variable in the given model that is being predicted is called the dependent variable.
