Answer: The probability for both is 1/2
Step-by-step explanation:
For A. The probability for who do or do not participate in some kind of sport is found by adding the students who do or do not. Which is 25 + 225 = 250
250 out of 500 simplified is 1/2
For B. The probability got who do and do not participate in some kind of sport is found by taking the number of students out of the whole number. Its 250 out of 500.
250 out of 500 is simplified to 1/2.
The first condition is for the perimeter of the equation so:
Now the secon condition is that the sum of two sides should be:
so the negative option and 0 don't make sence dor a distance, then we try with the value of b=0.5
So in the first equation will be:
So the condition:
this is false, so the solution is
