The houses can be placed in 362,880 ways.
<u>Step-by-step explanation:</u>
The 9 houses are each in different design.
The each lot can place any of the 9 houses.
- The 1st lot can place anyone house of all the 9 houses.
- The 2nd lot can place one of remaining 8 houses.
- The 3rd lot can place one of remaining 7 houses.
Similarly, the process gets repeated until the last house is placed on a lot.
<u>From the above steps, it can be determined that :</u>
The number of ways to place the 9 houses in 9 lots = 9!
⇒ 9×8×7×6×5×4×3×2×1
⇒ 362880 ways.
Therefore, the houses can be placed in 362880 ways.
Answer:

Step-by-step explanation:
Givens
- The railing will begin at 36 inches height.
- The slant decreases 9 inches for every 12 horizontal inches.
According to the problem, the slant is

The initial condition of the function is 36, which is a constant. Also, the slant is negative, because the problem states that "decreases".
If we see the problem form the perspective of a linear function, the constant ratio of change would be the slant.
Therefore, the linear function that models this problem is

So, the answer is the first choice.
Answer:
I subtracted the highest and lowest numbers. The range for new cars was 31. The range for old cars was 75. The range for used cars was much bigger.
