The piecewise function h(x) is shown on the graph.

On a coordinate plane, a piecewise function has 2 lines. The first line has a closed circle at (negative 4, 3) and goes down to a closed circle at (2, 0). The second line has an open circle at (2, 3) and goes up to a closed circle at (4, 5).

What is the value of h(2)?
−2
−1
0
3

Use the information in the table to select the true statement.

A.  

The 3rd nap is the least consistent in duration because its mean is the lowest.

B.  

The 3rd nap is the least consistent in duration because its standard deviation is the highest.

C.  

The 1st nap is the least consistent in duration because its mean is the highest.

D.  

The 2nd nap is the least consistent in duration because its standard deviation is the lowest.

Step-by-step explanation:

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
