Using proportions, it is found that there is a 0.54 = 54% probability that a randomly selected household owns a cat.
<h3>What is a proportion?</h3>
A proportion is a fraction of total amount.
In this problem, the proportions associated with owning a cat are given by:
- 70% of 60%(also have a dog).
- 30% of 40%(do not have a dog).
Hence:
p = 0.7(0.6) + 0.3(0.4) = 0.42 + 0.12 = 0.54.
0.54 = 54% probability that a randomly selected household owns a cat.

Area of the trapezium = 1/2 (40 + 160) x 70
Area of the trapezium = 7000 ft²
One bag of fertilizer = 4000 ft²
Number of bags of fertilizer needed = 7000 ÷ 4000 = 1.75 bags.
Since only full bags of fertilizer can be bought, 2 bags of fertilizer are needed.

Answer:
The length of the rectangle is 9 inches.
The height of the rectangle is 11 inches.
Step-by-step explanation:
Given : The volume of a rectangular solid can be written as V=LWH, where L is the length of the solid, W is the width, and H is the height. A box of cereal has a width of 2 inches. It’s height is 2 inches longer than it’s length. If the volume of the box is 198 cubic inches.
To find : What are the length and height of the box ?
Solution :
The width of the box is L inches
The width of the box is W=2 inches
The height is 2 inches longer than it’s length i.e H=L+2
The volume of a rectangular solid is ![V=L\times W\times H](https://tex.z-dn.net/?f=V%3DL%5Ctimes%20W%5Ctimes%20H)
![198=L\times 2\times (L+2)](https://tex.z-dn.net/?f=198%3DL%5Ctimes%202%5Ctimes%20%28L%2B2%29)
![99=L^2+2L](https://tex.z-dn.net/?f=99%3DL%5E2%2B2L)
![L^2+2L-99=0](https://tex.z-dn.net/?f=L%5E2%2B2L-99%3D0)
![L^2+11L-9L-99=0](https://tex.z-dn.net/?f=L%5E2%2B11L-9L-99%3D0)
![L(L+11)-9(L+11)=0](https://tex.z-dn.net/?f=L%28L%2B11%29-9%28L%2B11%29%3D0)
![(L+11)(L-9)=0](https://tex.z-dn.net/?f=%28L%2B11%29%28L-9%29%3D0)
![L=-11,9](https://tex.z-dn.net/?f=L%3D-11%2C9)
Reject L=-11 as dimension cannot be negative.
The length of the rectangle is 9 inches.
The height of the rectangle is 11 inches.
