In a density histogram the area of a region is equivalent to the density of that region. a. True
b. False

a. True

Step-by-step explanation:

Histograms are nothing but a way to representing data. They are often shown like the bar charts, but they show the frequency density and not the  frequency. The histograms are used to determine the information about the distribution of the given data.

The graph of the continuous distribution is represented by a curve and the area under the region of the curve is equal to the density of the region.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
