Answer: B) 18

Step-by-step explanation:

The degree of freedom for Standard error or df(Residual) is the sample size minus the number of estimated parameters ,.

df= n - p  , where n= sample size , p = number of parameters.

According to the given problem , we have

Sample size : n=20

Number of parameters (x and y ): p= 2

Then, the df value for the standard error of estimate will be :

df= n-p =20-2=18

Thus , the df value for the standard error of estimate is 18 .

Hence, the correct answer is B) 18 .

Roberto listed his assets and liabilities on a personal balance sheet.
mixer [17]
To see the effect on Robertos balance sheet, we will first have to get the total assets and liabilities
Total assets = cash+ investment+ house + car
Total liabilities= credit card + personal loan + mortgage  + car loan
Substituting the values, we will get
Total asset =$166000
Total liabilities =$1010000
Difference= $844000
To pay off car loan, he uses his investment
Total asset = $166000-5000
                   =$161000
Total liabilities= $1010000-5000
                        =$1005000
Difference=$844000
Therefore the answer is letter C, the difference between asset and liability will remain the same.

Here is the histogram of a data distribution. All class widths are 1. What is the median of this distribution?
Bingel [31]

Answer:

The median is 4.

Step-by-step explanation

if you layout all the number, you get

1,2,2,3,3,3,4,5,5,5,6,6,7

So, to find the median you find the number(s) right in the middle.

(Ex. 3,4,5; 4 is the median)

(Ex. 3,4,5,7; 4.5 is the answer)

The middle number of

1,2,2,3,3,3,4,5,5,5,6,6,7

is 4, so 4 is the median.

hope this helps. :)

Vlada [557]

We can apply Quadratic equations in real-world like; sports, bridges, projectile motion, shapes of bananas etc.

Following are three pictures of real world application of quadratics.

Example 1:- Here we can see a Cyclist follows a quadratic path to jump over the obstacles.

Example 2:- Here we see a man throwing a basketball towards the net following a slightly upward direction that goes through a quadratic path.

Example 3:- Here a football player kicks the ball in the sky and it goes through a quadratic path to cover some distance.
