I can answer the slopes
Answer:
1. would have a slope of 2
2. would have a slope of -1.66
3.would have a slope of 0
4. would have a slope of -13
Step-by-step explanation:
(Y2 - Y1) / (X2 -X1)
1. (9-5) / (4-2) = 4 / 2 =2
2. (-5-5) / (3 - -3) = -10 / 6 = 1.66
3. (2 - 2) / (5 - -4) = 0 / 9 = 0
4. (-7 - 6) / (3 - 3) = -13 / 0 = -13
Well what were given:
1 inch = 30 feet
The drawing of the building of this problem has the height of 1.25 inches and base of 0.75 inches.
Actual height:
1.25 inches * 30 feet/inch = 37.50 feet
Actual base:
0.75 inches * 30 feet/inch = 22.50 feet
So in this problem the answer would be "A" 22.50 Aka 22.5 For the building. Hope this helps you! (:

Answer:
45% probability that a randomly selected customer saw the advertisement on the internet or on television
Step-by-step explanation:
We solve this problem building the Venn's diagram of these probabilities.
I am going to say that:
A is the probability that a customer saw the advertisement on the internet.
B is the probability that a customer saw the advertisement on television.
We have that:
![A = a + (A \cap B)](https://tex.z-dn.net/?f=A%20%3D%20a%20%2B%20%28A%20%5Ccap%20B%29)
In which a is the probability that a customer saw the advertisement on the internet but not on television and
is the probability that the customers saw the advertisement in both the internet and on television.
By the same logic, we have that:
![B = b + (A \cap B)](https://tex.z-dn.net/?f=B%20%3D%20b%20%2B%20%28A%20%5Ccap%20B%29)
12% saw it on both the internet and on television.
This means that ![A \cap B = 0.12](https://tex.z-dn.net/?f=A%20%5Ccap%20B%20%3D%200.12)
20% saw it on television
This means that ![B = 0.2](https://tex.z-dn.net/?f=B%20%3D%200.2)
37% of customers saw the advertisement on the internet
This means that ![A = 0.37](https://tex.z-dn.net/?f=A%20%3D%200.37)
What is the probability that a randomly selected customer saw the advertisement on the internet or on television
![A \cup B = A + B - (A \cap B) = 0.37 + 0.2 - 0.12 = 0.45](https://tex.z-dn.net/?f=A%20%5Ccup%20B%20%3D%20A%20%2B%20B%20-%20%28A%20%5Ccap%20B%29%20%3D%200.37%20%2B%200.2%20-%200.12%20%3D%200.45)
45% probability that a randomly selected customer saw the advertisement on the internet or on television
