Answer:
5.3
Step-by-step explanation:
a² + b² =² c² the Pythagorean theorem
RQ² + RS² = QS² Solve RS
6² + RS² = 8²
RS² = 64 -36
RS² = 28
RS = √28 28 is slightly > 25 and since √25 =5
RS = 5.3 actually 5.2915 to a few more significant digits
When calculating probability you need to remember that probability is:
something that you are observing divided by total number of participants.
The number you get is relative value(has value between 0 and 1) and if you want to get it in percentage (more clearly) just multiply it with 100.
In this case we are observing blood type B persons. Number of them is 165.
Total number of persons is 1500. Therefore our calculation looks like this:
165/1500 = 0.11 or the probability is 0.11*100=11%
Answer:
so (know) the two points on the line then select one to be 1x, y1 and the other to be x2, y2 use what i just showed u to calculate the slope
Step-by-step explanation:
Step One: Identify two points on the line.
Step Two: Select one to be (x1, y1) and the other to be (x2, y2).
Step Three: Use the slope equation to calculate slope.
You didn’t solve for y correctly. Hope this helps
Answer: 0.79 or 79%
Step-by-step explanation:
Given : The probability that the athletes are football players : P(A)=0.33
The probability that the athletes are basketball players: P(B)=0.66
The probability that the athletes play both football and basketball : P(A∩B)=0.20
Now, the probability that the athlete is either a football player or a basketball player is given by :-

Hence, the probability that the athlete is either a football player or a basketball player = 0.79
Or we can write it as 79%.
