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 ..

Find The Value Of x ?

slega [8]

Answer:

1) $x = -1$ || 2) $x = 10$

Explanation:

→ $\log _3\left(\frac{1}{3}\right)=x$

→ $\frac{1}{3} = 3^x$

→ $3^{-1} = 3^x$

→ $x = -1$

→ $\log _3\left(x-1\right)=2$

→ $x - 1 = 3^2$

→ $x -1 = 9$

→ $x = 9 +1$

→ $x = 10$
