Answer:
C) (-6,0)(2,0)
For x-intercept, f(x) = 0:
This problem can be solved from first principles, case by case. However, it can be solved systematically using the hypergeometric distribution, based on the characteristics of the problem:
- known number of defective and non-defective items.
- no replacement
- known number of items selected.
Let
a=number of defective items selected
A=total number of defective items
b=number of non-defective items selected
B=total number of non-defective items
Then
P(a,b)=C(A,a)C(B,b)/C(A+B,a+b)
where
C(n,r)=combination of r items selected from n,
A+B=total number of items
a+b=number of items selected
Given:
A=2
B=3
a+b=3
PMF:
P(0,3)=C(2,0)C(3,3)/C(5,3)=1*1/10=1/10
P(1,2)=C(2,1)C(3,2)/C(5,3)=2*3/10=6/10
P(2,0)=C(2,2)C(3,1)/C(5,3)=1*3/10=3/10
Check: (1+6+3)/10=1 ok
note: there are only two defectives, so the possible values of x are {0,1,2}
Therefore the
PMF:
{(0, 0.1),(1, 0.6),(2, 0.3)}

this is answer
Step-by-step explanation:
Right now I don't have time. If u have doubt, send me a message. And I'll explain later.
hope it helps ☺️
4x + 100 > 7x
100 > 3x i moved all the x's over to one side
100/3 > x
or just
x > 100/3
so they need to sell more than 33.33333... pizzas
No one makes a 1.3333... pizza as far as I know, so your answer might be 34.
