Answer:
150 students
Step-by-step explanation:
According to statement we have the following information
number of juniors=n=300
mean score=24
standard deviation score=4
The number of students that score above 24 is determined by
Number of students score above 24=number of juniors* P(student score above 24)
P(student score above 24)=P(x>24)=P(x-mean/sd>24-24/4)=P(z>0)=0.5.
Students score above 24=np=300*0.5=150
Hence there are 150 students scored above 24.
Answer:
my answer is 9.25
Step-by-step explanation:
For this case we have the following expression:
![(2 \sqrt {27}) (3 \sqrt {32})](https://tex.z-dn.net/?f=%282%20%5Csqrt%20%7B27%7D%29%20%283%20%5Csqrt%20%7B32%7D%29)
We have to:
![27: 3 * 3 * 3: 3 ^ 2 * 3\\32: 16 * 2: 4 ^ 2 * 2](https://tex.z-dn.net/?f=27%3A%203%20%2A%203%20%2A%203%3A%203%20%5E%202%20%2A%203%5C%5C32%3A%2016%20%2A%202%3A%204%20%5E%202%20%2A%202)
Rewriting the expression and simplifying we have:
![(2 \sqrt {3 ^ 2 * 3}) (3 \sqrt {4 ^ 2 * 2}) =\\(2 * 3 \sqrt {3}) (3 * 4 \sqrt {2}) =\\(6 \sqrt {3}) (12 \sqrt {2}) =\\72 \sqrt {3 * 2} =\\72 \sqrt {6}](https://tex.z-dn.net/?f=%282%20%5Csqrt%20%7B3%20%5E%202%20%2A%203%7D%29%20%283%20%5Csqrt%20%7B4%20%5E%202%20%2A%202%7D%29%20%3D%5C%5C%282%20%2A%203%20%5Csqrt%20%7B3%7D%29%20%283%20%2A%204%20%5Csqrt%20%7B2%7D%29%20%3D%5C%5C%286%20%5Csqrt%20%7B3%7D%29%20%2812%20%5Csqrt%20%7B2%7D%29%20%3D%5C%5C72%20%5Csqrt%20%7B3%20%2A%202%7D%20%3D%5C%5C72%20%5Csqrt%20%7B6%7D)
Answer:
![72 \sqrt {6}](https://tex.z-dn.net/?f=72%20%5Csqrt%20%7B6%7D)
Answer:
Both of the lines that goes to A is the same length so just find the length measurement of the line fro C to A and the write that as the answer.
