BTW no calculator. Did it in my head. Hope this helps!
It makes sense to let the # of shirts sold be the variable dependent upon the unit cost per shirt.
Notice that the # sold declines as the price increases.
Thus, the slope of this line will be -.
8000 - 5000 3000 shirts
m = ------------------- = ----------------- = -200 shirts per dollar price increase
25 - 40 -15
Answer:
0.044
Step-by-step explanation:
n=9,p=0.9, x =6.
Apply Binomial probability we get
Sum P(x)=C(n,x) 
for x=6
Putting in the formula ,
we get
P(x) = C(9,6) 
84 X 0.531441 X 0.001
= 0.044
