Theoretical probability is determined through a study of the possible outcomes that can occur for the given experiment.
From the given scenario in this item, we can say that the sum of x and y is 500. By the aluminum balance, the equation that we can formulate from this,
0.25x + 0.40y = (500)(0.35)
The system of linear equations that can best express the given is,
x + y = 500
0.25x + 0.40y = 175
Answer = 96
Explanation is 2(4) = 8 so 24(4) = 96
Answer: Speed of the current is 3 miles per hour.
Step-by-step explanation:
Since we have given that
Speed of motor boat = 12 miles per hour
Distance traveled upstream = 45 miles
Let the speed of the current be x
Total time taken by upstream and downstream = 8 hours
Relative speed for downstream is given by
Relative speed for upstream is given by
According to question, we have
Hence, Speed of the current is 3 miles per hour.
The first step is to always do what is in the parenthesis. 6+8=14 is what you need to do then. Dividing it by 2 first is wrong because you are not following order of operations then. Now you do 14/2 which is 7. The first one is correct.
