Question

A density curve for all the possible weights between 0 pounds and 10 pounds is in the shape of a rectangle. What is the value of the density curve in this interval?
A. 0.001
B. 0.01
C. 0.0001
D. 0.1

Answer 1

The total area under the curve must equal 1. Let the value of the density curve be x. Then 10x = 1. Therefore x = 1/10 or 0.1.
The correct answer is D. 0.1.

Answer 2

Answer: D. 0.1

Step-by-step explanation:

Let x be the value of density curve in the interval from 0 to 10 pounds .Since, we know that the total area of a density curve = 1.

Now, the area covered by density curve is given by :-

$10\times x=1$

Dividing 10 on the both sides, we get

$x=0.1$

Therefore, the value of the density curve in this interval = 0.1
