Answer:

  • Is not met ( A )
  • Is not met ( A )
  • Does not need to be checked for multiple linear regression ( B )
  • Does not need to be checked for multiple linear regression ( B )

Step-by-step explanation:

Linearity condition is :  <em>NOT MET </em>

The equal variance condition is : <em>NOT MET</em>

The 10% condition :<em> Does not need to be checked for multiple linear regression </em>

The success failure condition : <em>Does not need to be checked for multiple linear regression</em>

Using the order of operations, what should be done first to evaluate (-2)^3 + 4 / (-15 + 9)(3) - 4
kogti [31]

Answer:

A. add -15 and 9

Step-by-step explanation:

We follow the PEMDAS rule as the order of operations to evaluate expressions.

P-Parenthesis

E-Exponents

M-Multiplication

D-Division

A-Addition

S-Subtraction

Given expression : (-2)^3+4\div(-15+9)(3)-4

In order to evaluate the expression, the first step would be to do the parenthesis operations which requires to add -15 and 9.

Find parametric equations for the line through point P(-4,5,2) in the direction of the vector (-6,6,-5)
tigry1 [53]

The vector <em>v</em> (-6, 6, -5) points in the direction of itself, so we start there.

We can capture all points on the line through the origin and the point (-6, 6, -5) by scaling <em>v</em> by an arbitrary real number <em>t</em>.

The line through point <em>P</em> and pointing in the same direction as <em>v</em> is parallel to the other line that passes through the origin. Then the line we want can be obtained by translating the line through the origin by a vector <em>p</em> that points to (-4, 5, 2), so the vector equation for this line is

<em>r </em>(<em>t </em>) = <em>p</em> + <em>t v</em>

<em>r </em>(<em>t </em>) = (-4, 5, 2) + <em>t</em> (-6, 6, -5)

<em>r </em>(<em>t </em>) = (-4 - 6<em>t</em>, 5 + 6<em>t</em>, 2 - 5<em>t</em> )

To get the parametric equations, simply take out the components:

<em>x</em> (<em>t</em> ) = -4 - 6<em>t</em>

<em>y </em>(<em>t</em> ) = 5 + 6<em>t</em>

<em>z</em> (<em>t</em> ) = 2 - 5<em>t</em>
