When an answer to a question uses the greater than symbol, that means any number above the number used is a possible answer to the equation. However, when it's just a simple "x = 2", then 2 is the only possible answer to that equation. Think about it as if it were on a graph. In the attached file I have a graph that is displaying the equation "x > 4". The entire shaded area to the right of 4 could be a possible answer.
Hope this helps.
The equation to find a z score is (x- mean)/(standard deviation)
So, in this case the equation would be
(76-70)/(2.1)
For,
X=76
Mean=70
Standard Deviation= 2.1
After solving we find that the z score equals 2.85714
or
2.8571
If hat is 5/8 then no hat is 8-5/8 = 3/8 and so on for the scarves. to find the probabilities multiply the cases you have.
The answer is C. 68/5 - 54/5i
Well since each shelf holds 40 you would add up the two shelves to 80 then add 5 on one shelve to get 85. Since he has room for 40 you would subtract 5 and get 35
