Let the first and smaller number be x. Since the second number is 5 times the first, the second number is 5x. We also know both of these numbers must add to 50; thus, we can create the following equation.
Combine like terms
Divide both sides by 6
This is the value of the first number. The number you're looking for isn't specified in the question description, so I'll just provide the value of the second number. The second number has to be 5 times the first.
Thus, we just multiply 5 to x.
That's the value of the second number.
Answer:
Lets assume that 1200 births are randomly selected and exactly 595 of the births are girls.
In percentage this is :
This is approx 50%. We can say that almost random 50% are girls.
So, It is unlikely because the probability of this particular outcome is very small, considering all of the other possible outcomes.
Part B: It is not unusual because 595 is about the number of girls expected.
