If a diagram has a scale of 1:100, that means that the real thing is 100 times larger. To find how long the real thing is, that means that we need to multiply the length on the diagram by 100. 100 * 15 is 1500. But, that is 1,500 cm. To convert it into meters, we need to divide by 100. That's because there's 100 centimeters in every meter. 1500/100 is 15, which means that the actual length of the car park is 15 meters. 
 
        
             
        
        
        
Answer:
The seconf option 
x = 0, 2, 4
y = 3,5,7
Step-by-step explanation:
plug in your x and y points into the equation and they should be the same of both sides 
ex (0,3)

Answer:
The probability  of selecting two Democrats and two Republicans is 0.4242.
Step-by-step explanation:
The information provided is as follows:
- A city council consists of seven Democrats and five Republicans.
- A committee of four people is selected.
In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.
The formula to compute the combinations of k items from n is given by the formula:

Compute the number of ways to select four people as follows:

Compute the number of ways to selected two Democrats as follows:

Compute the number of ways to selected two Republicans as follows:

Then the probability  of selecting two Democrats and two Republicans as follows:

Thus, the probability  of selecting two Democrats and two Republicans is 0.4242.
