0.09121×1000=<span>91
</span><span>if you have 21 bins then the 'middle bin' is bin 11 (starting at 1)
</span>
<span>So the 'mean' of this distribution is 11.
</span>
<span>Therefore from 1000 balls the number of balls is 0.91 x 1000.
</span>
So therefore the answer would be C
The lower bound is the smallest value that would round up to the estimated value. A quick way to calculate upper and lower bands is to halve the degree of accuracy specified, then add this to the rounded value for the upper bound and subtract it from the rounded value for the lower bound.

Answer: all real numbers greater than or equal to -3</h3>
Explanation:
The left-most point is at (-3,-2). The x coordinate is all we're concerned with here. The x coordinate for this point is x = -3. This is the smallest x value possible as an input. We cannot have x = -4 as that is nowhere on the blue curve.
So the domain is the set of real numbers x such that x is -4 or larger
In set builder notation, that would look like
In interval notation, we would say to indicate to the reader "have an interval from -3 to positive infinity; include the endpoint -3"
