Using probability of <u>complementary events</u>, it is found that there is a 0.41 probability that such a person moves to one of the higher income classes fifteen years later.
When two events are complementary, the <u>sum of their probabilities are 1</u>.
In this problem, <u>either a person moves to a higher income class or they do not</u>, hence, the events are <em>complementary</em>.
- 0.59 probability that a person does not move to a higher class.
- Hence, 1 - 0.59 = 0.41 probability that such a person moves to one of the higher income classes fifteen years later.

Answer: 180 milliliters
Step-by-step explanation:
There are 22 students and they are to put two spoonfuls into the container.
Total spoonfuls is:
= 22 * 2
= 44 spoonfuls
Each spoonful is 5 milliliters:
= 5 * 44
= 220 milliliters in total.
1 litre = 1,000 milliliters
0.4 litres in milliliters is:
= 0.4 * 1,000
= 400 milliliters
Amount of water left in milliliters is:
= 400 - 220
= 180 milliliters
Step-by-step explanation:
The solution is (-3,5)
The solution to a system of linear equations is just the intersection point
Answer:
30
Step-by-step explanation:
139+11 gives us 150 which is the total number of plates and 150/5= 30 so there were 30 plates in each package.
