Answer:
Probability of selecting a ball from the first ball if it is a blue ball = = 0.75
Step-by-step explanation:
Number of blue balls in the first box = 3
Number of blue balls in the second box = 1
Total number of blue balls = 3 + 1
Total number of blue balls = 4
Probability = (Number of possible outcomes)/(Number of total outcomes)
Probability of selecting a ball from the first ball if it is a blue ball = 3/4
Probability of selecting a ball from the first ball if it is a blue ball = = 0.75
Isolating 2abCos(c) on one side of the equation and using the given values of a, b and c we can find the answer to this question as shown below:
The information above is represented on a two-ways table as shown below.
Total students surveyed is 27 students
The relative frequency of people who exercise more than 5 hours and in the art class is 5/27
Answer: 1:10,000
Step-by-step explanation:
given data:
distance of the nearest star system = 100,000,000
distance to size ration of the sun earth system = 10,000
therefore;
100,000,000 / 10,000
= 10,000
The order of magnitude of the distance to size ratio of the Sun- Nearest Star system is about 1:10,000 times that of the Sun-Earth system.
