Answer Difference between the experimental and the theoretical probability is 2/5 . Step-by-step explanation: Spinner is spun 10 times, and experimental probability of landing on a 3 is 1/2, i.e. out of 10 times spinner lands 5 times into 3.
I hope it is helpful
Your answer is -2 as the axis of symmetry is at -b/2a. So if you were to expand the equation, you would get y= x^2/4 +x -6 where b is 1 and 2a is ½ . Therefore -1 / ½ gives you -2
Answer:
Step-by-step explanation:
50t=500(8.5)
t=10(8.5)
t=85 minutes
The solution is the interval b is in ]11.3, infinity[
I personally think Natalie's bill is the greatest because $24.25 × 10 =x
