Answer:
A)0.5
Step-by-step explanation:
We can see in the graph , that it is bell-shaped along x =2. A bell-shaped graph along one value is called symmetric graph and it represents a normal distribution.
Since, the give graph is symmetric around x=2, so the mean of the data is 2.
The point immediate left to the mean represents x-σ
so,
2 - σ = 1.5
So,
σ = 0.5
The sigma represents standard deviation.
Hence, Option A is correct ..
Since we know the values of the variables, we can simply plug them in and use pemdas to solve.
4 + 5(6)
4 + 30
answer = 34
hope this helps!
Subtract 6 from each side. Then you have an absolute value equal to -6. But an absolute value is never negative. So there is no solution.
Provided in the question, total number of people that can be accommodated in the theatre are 471.
- Now, 254 people are seated
- p is the number of people who can enter the theatre of the movie.
Then, according to the question there are two possibilities. The number of people is less than the total number of People who can be accommodated.
Or, they can be equal to the number of people.
Combining both the inequations, We get
So, the correct option is Option D
