The graph shows a distribution of data. What is the standard deviation of the data? A)0.5 B)1.5 C)2.0 D)2.5
ruslelena [56]

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 ..

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.

Write an equation/inequality to represent the description. *
KiRa [710]

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.

1) \: p + 254 < 471

Or, they can be equal to the number of people.

2) \: p + 254 = 471

Combining both the inequations, We get

\boxed{   p + 254 \leqslant 471}

So, the correct option is Option D
