Use the value of the linear correlation coefficient r to find the percentage of the total variation that can be explained by the linear relationship between the two variables. r = 0.234 (Your answer should be a percent rounded to two decimal places as needed.)

Answers

Answer 1

Answer:

5.47% of the total variation between the two variables can be explained by the regression line.

Step-by-step explanation:

Given :

R value = 0.234

The R value is the correlation Coefficient ; which gives the type and level of correlation between two variables.

However, to Obtian the percentage variation which can be explained by by the regression line, we have to obtain the Coefficient of determination, R².

R² value is Obtained by taking the squared of the correlation Coefficient

Hence,

R² = 0.234² = 0.054756

R² = 0.05476 * 100% = 5.4756%

Hence, R² = 5.48%

This is interpreted as ; 5.47% of the total variation between the two variables can be explained by the regression line.

Write code to complete doublepennies()'s base case. sample output for below program: number of pennies after 10 days: 1024 note: these activities may test code with different test values. this activity will perform three tests, with starting pennies = 1 and userdays = 10, then with starting pennies = 1 and userdays = 40, then with startingpennies = 1 and userdays = 1. see how to use zybooks. also note: if the submitted code has an infinite loop, the system will stop running the code after a few seconds, and report "program end never reached." the system doesn't print the test case that caused the reported message.

The doublePennies() function is an illustration of a recursive function in Java

How to complete the doublePennies() function?

The base case of the doublePennies() function is that:

When the number of days is 0, then the total available pennies is the same as the total number of pennies.

The algorithm of the above highlight is:

if numDays equals 0 then

totalPennies = numPennies

Using the above algorithm, the complete base case is:

if(numDays == 0){

totalPennies = numPennies;

}

Write the partial fraction decomposition of the rational expression. Check your result algebraically.

Answers

Answer:

See below.

Step-by-step explanation:

First, distribute:

$=(1)/(x(x+1))$

Now, perform partial fraction decomposition. This is only two factors, so we only need linear functions:

$(1)/(x(x+1)) =(A)/(x)+(B)/(x+1)$

Now, multiply everything by x(x+1):

$1=A(x+1)+B(x)$

Now, solve for each variable. Let's let x=-1:

$1=A(-1+1)+B(-1)$

$1=0A-B=-B$

$B=-1$

Now, let's let x=0:

$1=A(0+1)+B(0)$

$A=1$

So:

$(1)/(x(x+1))=(1)/(x)-(1)/((x+1))$

Double Check:

$(1)/(x)-(1)/((x+1))=((x+1))/(x(x+1))-(x)/(x(x+1))$

$=(x-x+1)/(x(x+1)) =(1)/(x^2+x)$

Employees at a large company are surveyed about their health insurance status. Employees are coded as "1" if health insurance is obtained through the company’s benefit program, "2" if health insurance is obtained from another source (such as through a spouse’s employment benefit program), or "0" if the employee does not have health insurance. This variable is:categorical numerical quantitatively categorical All answers of the answer options are correct.

Answers

Answer:

Categorical is the correct answer to this question.

Step-by-step explanation:

The variable class standing is "Categorial".

As a categorical variable, it is a factor that can accept one of a small, and typically set, range of additional values, assigned each person, and another unit of measurement to a specific group or marginal class on the grounds of some long-lasting.
The data obtained may be either prescriptive or numeric.
Numbers also make no sense when you allocate significance to certain numbers.
Categorical data will help you go there. Classic data is when statistics are obtained in classes or categories.

The slope of a line can be found, given two points, as follows:

$P_(1)(-5.5,6.1) \n \n P_(2)(-2.5,3.1) \n \n m=(y_(2)-y_(1))/(x_(2)-x_(1)) \n \n m=(3.1-6.1)/(-2.5-(-5.5))=-1$

So this slope tells us the direction of a line and represents the vertical change divided by the horizontal change.
