Which of the following is not a property of the f distribution? choose the correct answer below. a. values in the f distribution cannot be negative. b. the exact shape of the f distribution depends on the two different degrees of freedom. c. the f distribution is not symmetric. d. the f distribution is bell shaped.

The correct answer is D..

Step-by-step explanation:

The F-distribution, or Fisher-Snedecor distribution is a well known probability distribution with many applications in Statistics. The graph of its probability density function has several shapes depending of the parameters. Recall that the F-distribution has two free parameters. In the attached graph (https://en.wikipedia.org/wiki/F-distribution#/media/File:F-distribution_pdf.svg) it is shown different shapes of the F-distribution in terms of different values of the parameters.  

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25
