Answer:
Option C is correct.
The value of x nearest to tenth is, 21.4 units
Step-by-step explanation:
In a given right angle triangle;
by definition of tangent ratio i,e ![\tan \theta = \frac{opposite side}{Adjacent side}](https://tex.z-dn.net/?f=%5Ctan%20%5Ctheta%20%3D%20%5Cfrac%7Bopposite%20side%7D%7BAdjacent%20side%7D)
![\tan 25^{\circ} = \frac{10}{x}](https://tex.z-dn.net/?f=%5Ctan%2025%5E%7B%5Ccirc%7D%20%3D%20%5Cfrac%7B10%7D%7Bx%7D)
![0.46630765815 = \frac{10}{x}](https://tex.z-dn.net/?f=0.46630765815%20%3D%20%5Cfrac%7B10%7D%7Bx%7D)
or
units
Therefore, the value of x nearest to tenth is, 21.4 units
Answer:
The answer of 7⁵ is 16,807
Step-by-step explanation:
You would write 7x7x7x7x7 and get 49x49x7. you then do 49x49 which is 2,401 then multiply that by 7.
There is no following by the ratio of white to red is 5:12 so if you multiply any of those 2 numbers you’ll get it right
Answer:
2.0
Step-by-step explanation:
Couldn't really understnd what you wrote but I'll assume it's the standard deviation of a fair, 7-sided die
The standard deviation is just the square root of the variance (which is just the second moment minus the first moment squared)
The first moment (AKA the average is..)
![\frac{1+2+3+4+5+6+7}{7}=4](https://tex.z-dn.net/?f=%5Cfrac%7B1%2B2%2B3%2B4%2B5%2B6%2B7%7D%7B7%7D%3D4)
The second moment is..
![\frac{1^2+2^2+3^2+4^2+5^2+6^2+7^2}{7}=20](https://tex.z-dn.net/?f=%5Cfrac%7B1%5E2%2B2%5E2%2B3%5E2%2B4%5E2%2B5%5E2%2B6%5E2%2B7%5E2%7D%7B7%7D%3D20)
![\sqrt{20-4^2}=2](https://tex.z-dn.net/?f=%5Csqrt%7B20-4%5E2%7D%3D2)
