Gina surveyed students about their lunch time preference. Out of 50 students, 20 prefer eating lunch at 11:00am, 15 prefer eating at 11:15a.m., 10 prefer eating at 11:30a.m. , and 5 have no preference. Based on the information, what is the probability that a student chosen at random has no lunch time preference?
The answer would be Always
Hope this helped! :D
Answer:
19, 21, and 23.
Step-by-step explanation:
-4.6, -0.7, 4/8
Least to greatest
Mathematically, when you calculate the inverse function (f-1(x)), you’re switching the “inputs” (x) and the “outputs” (f(x)) and then re-solving the equation. So, you’d start with something like:
x = 3*f-1(x) + 3
x - 3 = 3*f-1(x)
(x - 3)/3 = f-1(x)
Your inverse formula would be (x - 3)/3. Hope this helps! (Hopefully Brainly doesn’t mess up the text format.)
