Answer:
1710
Step-by-step explanation:
GPA = 3,1 +- 0,6
0,6 = 2*STDEV
As it is a normal distribution, the interval (Mean +- 2*STDEV) includes 95% of the students.
1800 * 0,95 = 1710
Answer:
41.6666666 the 6 will go one for ever
Step-by-step explanation:
Answer: second option.
Step-by-step explanation:
You need to descompose the radicand 8 and the radicand 50 into their prime factors:
![8=2*2*2=2^2*2\\50=2*5*5=2*5^2](https://tex.z-dn.net/?f=8%3D2%2A2%2A2%3D2%5E2%2A2%5C%5C50%3D2%2A5%2A5%3D2%2A5%5E2)
Then you can rewrite the expression:
![\sqrt{8}+\sqrt{50}](https://tex.z-dn.net/?f=%5Csqrt%7B8%7D%2B%5Csqrt%7B50%7D)
![=\sqrt{2^2*2}+\sqrt{2*5^2}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B2%5E2%2A2%7D%2B%5Csqrt%7B2%2A5%5E2%7D)
Since:
![\sqrt{a^2}=a](https://tex.z-dn.net/?f=%5Csqrt%7Ba%5E2%7D%3Da)
You can simplify the expression:
![=2\sqrt{2}+5\sqrt{2}](https://tex.z-dn.net/?f=%3D2%5Csqrt%7B2%7D%2B5%5Csqrt%7B2%7D)
As the indices and the radicands are the same, you can make the addition:
![=7\sqrt{2}](https://tex.z-dn.net/?f=%3D7%5Csqrt%7B2%7D)
