Answer:A)0.5 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 ..
Step-by-step explanation:and what is on d is 2.5
Orientation may change, but the measure of its angles will stay the same. A translation does not change the shape of a figure, it only moves its location and direction.<span />
