A researcher found a study relating the value of a car, y, to the age of the car, x. When researchers looked at the association
vredina [299]

Answer: c) About 16% of the variation in value of the car is explained by a linear relationship with the age of the car.

e) The correlation coefficient, r, is 0.397.

Step-by-step explanation:

Given that:

Coefficient of determination (r²) between two variables, age of car (x) and value of car (y) = 0.158

Correlation of determination (r²) of 0.158 = (0.158 × 100% = 15.8% of the variation between the two variables can be explained by the regression line). Hence, about 16% of the variation between age and value of car can be explained by the linear relationship.

Coefficient of correlation (r) = sqrt(r²) = sqrt(0.158) = 0.397

How do you write 6,301.005 in standard form
Orlov [11]
<h3>Answer:</h3>

One of ...

  • 6,301.005
  • 6.301005×10³
<h3>Step-by-step explanation:</h3>

It depends on where you are.

In the US, standard form is the way you have written the number. Your number would be 6,301.005.

The attachment gives some guidance for number formats in American publications. In certain publications, thin spaces are used instead of commas to separate groups of digits. The comma (or space) is often optional, but can enhance readability for large numbers.

In Britain, standard form is the form called "scientific notation" in the US. Your number would be 6.301005×10³.
