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:
Its a square. if you graph it, you would see.
Step-by-step explanation:
Answer: Choice A) It has a range of 17
Reason:
The smallest value is 8 and the largest is 14. The range is the distance between these min and max
range = max - min = 14 - 8 = 6
So the range is 6 instead of 17.
Answer:
8![\sqrt{x}](https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D)
Step-by-step explanation:
300x60= 18,00
Answer:
Estimate is 150 and actual product is 138.
Step-by-step explanation:
To estimate products, we round the numbers to nearest unit place, 10th, 100th, 1000th, and so on.
Given are the numbers 3 and 46.
We can round 46 ≈ 50.
So Estimation would be 3 x 46 ≈ 3 x 50
3 times 5 is 15 and we can add zeros after it.
So estimation is 3 x 46 ≈ 150.
Now actual product would be...
3 times 6 is 18, so we note down 8 and 1 goes to carry over 4.
3 times 4 is 12 and carry 1 will be added in it, so 12 + 1 = 13.
It means the actual product is 3 x 48 = 138.
