Her statement is not reasonable because it is not true that 25% of female marathoners run 13 or more miles a week, it is true that 25% run less than 13 miles a week (out of the data). The rest of the data would be 75%, making the statement, "75% of female marathoners run 13 or more miles a week" true. The way she recorded the data does not interfere with the statement being reasonable since it is unbiased.

Answer:
(x+1) (x-1) (x+2) (x-2)
Step-by-step explanation:
<u>Let u = x^2</u>
= u^2 - 5u + 4
<u>(Factor u^2 - 5u + 4)</u>
= (u-1) (u-4)
<u>Substitute back u = x^2</u>
= (x^2 -1 ) (x^2 - 4)
<u>Factor x^2 - 1 and x^2 -4</u>
= (x+1) (x-1) (x+2) (x-2)
Hope this helped... :)
