Answer:

105/330 = 21/66 = 7/22

7/22 is the answer I think

Step-by-step explanation:

n(U) = 330

n(A) = 85

n(B) = 200

n(A n B) = 60

Now,

n(A U B) = n(A) + n(B) - n(A n B)

or, n(A U B) = 85 + 200 - 60

or, n(A U B) = 285 - 60 = 225

Now,

n(A U B) compliment = n(U) - n(A U B)

n(A U B) compliment = 330 - 225

so, n(A U B) compliment = 105

Now,

probability = 105/330

Which is the graph of linear inequality 6x+2y>-10
NemiM [27]
For this case we have the following inequality:
 6x + 2y\ \textgreater \  -10

 The first thing we must do is to graph the linear function:
 6x + 2y = -10

 Then, we must evaluate ordered pairs in the following way:
 (x, y)
 The ordered pairs that meet the inequality, will be included as part of the graph.
 Therefore, the shaded region contains all the ordered pairs that meet the inequality.
 Answer:
 See attached image.

This is correct? I need help please :(
Leto [7]

Answer:

well, we only no that

2l + 2w is 80

(lengths and widths on all 4 sides

and that w * l is A

so the function should be w times what's left for l, but also expressed by something with w

2l + 2w = 80 | -2w

2l = 80 -2w | devide by 2

l = 80 - w

now we can substitute l in

A = w * l

so that we only need w's

A(w) = w * (80-w)

for any w it will give us the area, makes only sense for 0<w<80
