Answer:
-1
Step-by-step explanation:
Given,
f(x) = -x² + 4x - 1 and x = 0
Putting the value of x we get,
f(0)= + (4 X 0) - 1
= -0+0-1
=-1
∴f(x)= -1
So, the required value is -1

<u>Answer:</u>
2. The correct answer option is 25%.
3. The experimental probability is 3% greater than the theoretical probability.
<u>Step-by-step explanation:</u>
2. We are given that a number cube is rolled 20 times out of which 5 times it lands on the number 2.
We are to find the experimental probability of getting the number 2.
P (2) = = 25%
3. The theoretical Outcomes are: HH HT TH TT
So theoretical probability of getting HH = = 25%
Total number of outcomes = = 100
So experimental probability of getting HH = = 28%
Therefore, the experimental probability is 3% greater than the theoretical probability.
