Answer:
The probability of cured people in who took the remedy is 8/9.
Step-by-step explanation:
Success rate of the cold remedy = 88%
The number of people who took the remedy = 45
Now, 88% of 45 = 
and 39.6 ≈ 40
So, out of 45 people, the remedy worked on total 40 people.
Now, let E: Event of people being cured by cold remedy
Favorable outcomes = 40

or,
= 
Hence, the probability of cured people in who took the remedy is 8/9.
The opposite of 17.2 from 0 on a number line would be -17.2.
Answer:
y = 3x
Step-by-step explanation:
Given
9x - y = - 6x + 4y ( subtract 4y from both sides )
9x - 5y = - 6x ( subtract 9x from both sides )
- 5y = - 15x ( divide both sides by - 5 )
y = 3x
4x40= 160
6x40= 240
160/12= 13.33
240/12= 20
13.33x20= 266.6
The answer is 266.6 square feet
