Answer:
see in the picture, the perimeter of this rectangle is
2( x + 3x) = 8x but the perimeter is 65.6
=> 8x = 65.6
<=> x = 65.6/8
=> x = 8.2
If it’s a triangle then it has to equal 180
so 48+54+x=180
48+54=102
180-102=x
x=78
Answer:
68.27%
Step-by-step explanation:
By the Empirical Rule, as 65% and 75% are both one standard deviation apart from the mean of 70%, then this represents 68.27% of the data.

The function 
doesn't have inverse because it doesn't pass the horizontal line test. This test tells us that a function 
has an inverse function<em> if and only if</em> there is no any horizontal line that intersects the graph of at more than one point. As you can see, from the graph of f (the red one), if you draw an horizontal line that passes through 
then this line will touch the graph of f at three points, so the horizontal line test is not satisfied here. If you see the graph of g, this doesn't represent a function because there is at least one vertical line that touches the graph at more than one point, so this relation is not a function.
