Answer:
![2 \sqrt{15}](https://tex.z-dn.net/?f=2%20%5Csqrt%7B15%7D%20)
Step-by-step explanation:
1) rewrite 60 as it's prime factors.
![\sqrt{2 \times 2 \times 3 \times } 5](https://tex.z-dn.net/?f=%20%5Csqrt%7B2%20%5Ctimes%202%20%5Ctimes%203%20%5Ctimes%20%7D%205)
2) group the smae prime factors into pairs.
![\sqrt{(2 \times 2)} \times 3 \times 5](https://tex.z-dn.net/?f=%20%5Csqrt%7B%282%20%5Ctimes%202%29%7D%20%20%5Ctimes%203%20%5Ctimes%205)
3) Rewrite each pair in exponent form.
![\sqrt{ {2}^{2} \times 3 \times 5 }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%7B2%7D%5E%7B2%7D%20%5Ctimes%203%20%5Ctimes%205%20%7D%20)
4) use this role:
![\sqrt{ {x}^{2} } = x](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%7Bx%7D%5E%7B2%7D%20%7D%20%20%3D%20x)
![2 \sqrt{3 \times 5}](https://tex.z-dn.net/?f=2%20%5Csqrt%7B3%20%5Ctimes%205%7D%20)
5) Simplify.
![4 \sqrt{15}](https://tex.z-dn.net/?f=4%20%5Csqrt%7B15%7D%20)
So, therefor, the answer is option 1.
Answer:
Do repeated addition
Step-by-step explanation:
For example 12 * 12 = 144 because 12+12+12+12+12+12+12+12+12+12+12+12=144
Answer: 0 slope
The y coordinat for both points is the same and there is no change in slope so it's a 0 slope
Answer:
10.8 units
Step-by-step explanation:
The answer is 0.50.
P(4<=X<=8)=P(x=4)+ P(x=5)+ P(x=6)+ P(x=7)+ P(x=8)= 0.05+ 0.15+0.15+0.15 +0 = 0.50
Notice that in 8 the line touches the x axis so it’s corresponding probability is 0.
