Required
Probability that 2 of 3 use sunscreen
From the attached data, we have:
![S = \{275, 738, 419, 582, 987, 436, 578, 472, 178, 839\}](https://tex.z-dn.net/?f=S%20%3D%20%5C%7B275%2C%20738%2C%20419%2C%20582%2C%20987%2C%20436%2C%20578%2C%20472%2C%20178%2C%20839%5C%7D)
![n(S) = 10](https://tex.z-dn.net/?f=n%28S%29%20%3D%2010)
Events where 2 of the 3 uses sunscreen is:
--- i.e. where 0 -5 represents sunscreen
![n(x) = 5](https://tex.z-dn.net/?f=n%28x%29%20%3D%205)
So, the required probability is:
![Pr = \frac{n(x)}{n(S)}](https://tex.z-dn.net/?f=Pr%20%3D%20%5Cfrac%7Bn%28x%29%7D%7Bn%28S%29%7D)
![Pr = \frac{5}{10}](https://tex.z-dn.net/?f=Pr%20%3D%20%5Cfrac%7B5%7D%7B10%7D)
![Pr = 0.50](https://tex.z-dn.net/?f=Pr%20%3D%200.50)
Answer:
![\sqrt{30}](https://tex.z-dn.net/?f=%20%5Csqrt%7B30%7D%20)
can not be simplified further.
Decimal = 5.477225575
The answer is E. The average rate of change of a function is f(b) - f(a) divided by (b - a). if you use the interval from answer E, you get f(1)-f(-5)divided by (1+5). plugging those numbers into the equation gets you to 4-16/6 which is -12/6 which equals -2
Answer:
No
Step-by-step explanation:
The only arithmetic sequence of side lengths that will form a right triangle is (3, 4, 5) or some multiple of that, such as (9, 12, 15).
Sides of length 10, 11, 12 cannot form a right triangle.
