In a multiple regression analysis what would likely be the culprit of a dramatic increase in the P-value of one of the variables

makvit [3.9K]

This can happen if you add another independent variable to your regression model that is strongly correlated to some other variable already in the model.
This is called multicollinearity.
If there is a high correlation between your independent variables can lead to problems.
<span>It can lead to increased variance of the coefficient estimates and make the estimates very sensitive to minor changes in the model.</span>

The table below shows a pattern in the cost of renting a car based on the number of days rented. Car Rentals Number of Days (d)

andrezito [222]

The linear equation that describes the pattern in the cost of renting a car is given by:

D. c = 34d + 25

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

A linear function is modeled by:

$y(x) = mx + b$

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0.

In this problem:

For each day, the cost of renting a car increases by 34, hence, the slope is of 34, and the equation is:

$c(d) = 34d + b$

When d = 4, c = 161, and this is used to find b.

$c(d) = 34d + b$

$161 = 34(4) + b$

$b = 25$

Hence, the equation is c = 34d + 25, and option D is correct.

System of linear equations.<br> 2x + 4y =, 10<br> 2x + 2y + 3z = 3<br> -3x + y + 2z = -3

Dimas [21]

Answer:

x = 1, y = 2, z = -1

Step-by-step explanation:

2x + 4y = 10

2x = -4y + 10

x = -2y + 5

now sub -2y + 5 in for x, back into the other 2 equations

2x + 2y + 3z = 3 -3x + y + 2z = -3

2(-2y + 5) + 2y + 3z = 3 -3(-2y + 5) + y + 2z = -3

-4y + 10 + 2y + 3z = 3 6y - 15 + y + 2z = -3

-2y + 3z = 3 - 10 7y + 2z = - 3 + 15

-2y + 3z = - 7 7y + 2z = 12

-2y + 3z = -7....multiply by 2

7y + 2z = 12...multiply by -3

--------------------------

-4y + 6z = -14 (result of multiplying by 2)

-21y - 6z = -36 (result of multiplying by -3)

---------------------------add

-25y = - 50

y = -50/-25

y = 2 <===

2x + 4y = 10 2x + 2y + 3z = 3

2x + 4(2) = 10 2(1) + 2(2) + 3z = 3

2x + 8 = 10 2 + 4 + 3z = 3

2x = 10 - 8 6 + 3z = 3

2x = 2 3z = 3 - 6

x = 2/2 3z = -3

x = 1 <== z = -3/3

z = -1 <===

The tempature is -3 degress.The temperature is expected to decrease 2.5 degress each hour until the temperature reaches -18 degr

Andrews [41]

We can set this problem up as an algebraic equation, which we can then solve to find our answer.

We start at -3. So we can start our equation with that:

$-3$

However, this doesn't represent any change in temperature, just that we start at -3. To show change, we will use the variable $x$ , where $x$ stands for the number of hours. Each hour accounts for a change of -2.5 in degrees, meaning that we must multiply our $x$ by -2.5. We can now add this term into our equation:
