Since the average height is 60 inches and its deviation is 2 inches, one deviation to the right (or higher) is 62 inches (60 + 2). Two deviations is 64 inches, three deviations is 66 inches, and four deviations is 68 inches.
Since the average weight is 100 pounds and its deviation is 5 inches, we repeat the process from finding heights to get to 115 pounds. That takes three deviations.
The MORE deviations away, the more unusual it is. So the height (4 deviations) is more unusual than the weight (3 deviations).
Answer:
becaudse theyu dont match
Step-by-step explanation:
i got it right
Here is the basis equation.
Let us use the AC method. Multiple the A and C values, or 3 and -5. This is -15. So now ask yourself... what multiplies to -15 but adds to -2. that would be, -5 and 3. So now reconstruct your equation ...
The larger number will go first (3>-5)
Now you can factor each group.
Because what is now in the parentheses are qualm and they are being added, you can now make the coeffecients a group
If you are solving for p, set equal to zero and then the answers are -1 and (5/3). If you are just factoring, then that is your answer.
Total flights = 108
Flights which are longer than 3 hours = 20
Probability = 20/108 = 5/27
