<span>if you have 21 bins then the 'middle bin' is bin 11 (starting at 1)
So the 'mean' of this distribution is 11.
The SD is 3
so using the above calculator (or your own tables ) you get that the probability of a ball being in bin 7 or less is .091
A is you answer

Answer:
The equation that represents the table is:
Step-by-step explanation:
Taking two points from the table




As the slope-intercept form is

Plugging (2, 9) to find the y-intercept 'b'







so the equation becomes



Therefore, the equation that represents the table is:
The graph of the equation is also attached below.
Answer:9x10⁴
Step-by-step explanation:
1.7x10⁵-8*10⁴=10⁴(1.7x10-8)=10⁴(17-8)=9x10⁴
