200 miles over 5 inches = 50 miles over x inches
200/5 = 50/x = 200x/250 =
x = 250/200 = 1.25
1.25 inches = 50 miles
Answer:
1. -49
2. -8
Step-by-step explanation:
1. For there to be infinite solutions the left and right sides must be identical.
-7(2x + 7) + 10x
= -14x - 49 + 10x
= -4x - 49
Thus the blank space must contain -49.
2. For there to be no solution the terms in x must be the same on both sides and the numbers different.
As you see the numbers are different. The answer is the x term on the left side = -8x, as the x terms on the right simplify to -8x.
-8 goes in the blank space.

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.
