I was actually just learning this. ^-^
To find the intersection, look at the numbers. and see what numbers do both groups have in common.
In this case, we have { 2, 4, 6, 9 } and { 3, 5, 8 }
As you can see, they both have nothing in common. Number wise.
So the answer would be Null.
Answer:
V=1
Step-by-step explanation:
Your answer would be 104 in^2
You would cut the shape to make both rectangles separate, then you would find the area of those rectangles and add them together to get the total area.
1st Rectangle- 12 x 7= 84in
2nd Rectangle- 5 x 4= 20in
84 + 20= 104in^2
Hope this helps :)
Answer:
No, they are not mutually exclusive because a customer can purchase a burger and fries together.
Step-by-step explanation:
Mutually exclusive events are events that cannot occur at the same time, e.g. I cannot sleep while running. In the case of a restaurant, you could consider purchasing pizza and burgers as mutually exclusive since most people would only purchase one of them (unless they eat a lot). But burgers and fries are not mutually exclusive because people can purchase them together.
Answer:
(0, 7]
Step-by-step explanation:
Let's call the width W and the length L. The length is 18 feet more than the width, so:
L = W + 18
The area can be no more than 175, so:
A ≤ 175
LW ≤ 175
Since L = W + 18:
(W + 18) W ≤ 175
W² + 18W ≤ 175
W² + 18W - 175 ≤ 0
(W - 7) (W + 25) ≤ 0
-25 ≤ W ≤ 7
However, the width of the table can't be nonpositive, so:
0 < W ≤ 7
Or in interval notation, (0, 7].
