Answer:
And we can find this probability using the normal standard distribution, excel or a calculator and we got:
And if we convert this into percent we got 84.13% rounded to the nearest percent would be:
84%
Step-by-step explanation:
Let X the random variable that represent the circumferences of a population, and for this case we know the distribution for X is given by:
Where 
and 
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the normal standard distribution, excel or a calculator and we got:
And if we convert this into percent we got 84.13% rounded to the nearest percent would be:
84%

Answer:
The inequality for the given graph is 
.
Step-by-step explanation:
From the given graph it noticed that the line passing through (0,-1) and (3,1).
The equation of line passing through two points is defined as
The equation of line is
Therefore the related equation is .
The point (0,0) lies in the shaded region, therefore the point (0,0) is the solution of required inequality.
Put (0,0) in the related equation.
Since 0 is greater than -1, therefore the sign of inequality must be >. The related line is a dotted line, therefore we cannot use 
.
Therefore the required inequality is
Answer:
it's the last one
Step-by-step explanation:
just look up "reciprocal" lol
this is just a definition
