Step-by-step explanation:
So, 3x^3 - 18x^2 - 9x + 132 = 0
The answer would be
Exact Form: 4, 1 + 2 \3, 1 - 2 \3
Decimal Form: 4,4.6410161...., -2.46410161
Hope this Helps :D
It appears that there are 30 students total (14 Male students and 16 Female Students)
We are interested in selecting a male student, and the probability of that happening is 14/30 which simplifies to 7/15
7/15 becomes 0.4667
Convert 0.4667 to a percentage and you are left with 46.67%
Rounded to the nearest whole percent, you get 47%
Answer: 47%
Answer:
The standard deviation will be: 2.1
Step-by-step explanation:
We know that standard deviation is basically the square root of variance.
Using the formula to calculate the standard deviation
![s=\sqrt{s^2}](https://tex.z-dn.net/?f=s%3D%5Csqrt%7Bs%5E2%7D)
As
so the standard deviation can be calculated as:
standard deviation ![=\sqrt{s^2}](https://tex.z-dn.net/?f=%3D%5Csqrt%7Bs%5E2%7D)
![=\sqrt{\left(4.4\right)^}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B%5Cleft%284.4%5Cright%29%5E%7D)
![=2.1](https://tex.z-dn.net/?f=%3D2.1)
Therefore, the standard deviation will be: 2.1
Answer:
![the \: answer \: is \: choice \: b \: \frac{ - 2 \sin(x) }{1 + \cos(x) }](https://tex.z-dn.net/?f=the%20%5C%3A%20answer%20%5C%3A%20is%20%5C%3A%20choice%20%5C%3A%20b%20%5C%3A%20%20%5Cfrac%7B%20-%202%20%5Csin%28x%29%20%7D%7B1%20%2B%20%20%5Ccos%28x%29%20%7D%20)
