Answer:
-5/2+-1/2√37≤x≤-5/2+1/2√37
Step-by-step explanation:
Step 1: Find the critical points
-x^2-5x+3=0
For this equation: a=-1, b=-5, c=3
−1x^2+−5x+3=0
x=−b±√b2−4ac/2a
x=−(−5)±√(−5)2−4(−1)(3)/2(-1)
x=5±√37
/−2
x=-5/2+1/2√37
Step 2: Check intervals in between critical points
x≤-5/2+1/2 √37 (Doesn't work in original inequality)
-5/2+-1/2√37≤x≤-5/2+1/2√37 (Works in original inequality)
x≥-5/2+1/2 √37 (Doesn't work in original inequality)

In the following data set, what is the range? 3, 7, 8, 4, 4, 5, 9, 10, 6, 2
OleMash [197]
To find range tou must order the numbers so they are least to greatest. Then you subtract the smallest value from the greatest value.
2,3,4,4,5,6,7,8,9,10
10-2=8
Range=8
I believe that the answer is 6
