Answer:
![A(\frac{\sqrt{3} }{2} ,\frac{1}{3})\\ \\and\\\\B( 1, 1)](https://tex.z-dn.net/?f=A%28%5Cfrac%7B%5Csqrt%7B3%7D%20%7D%7B2%7D%20%2C%5Cfrac%7B1%7D%7B3%7D%29%5C%5C%20%5C%5Cand%5C%5C%5C%5CB%28%201%2C%201%29)
Point A {√3 /2 ,1 /3}
Point B { 1, 1}
could not be the points on the unit circle.
Step-by-step explanation:
Unit circle :
A circle having a radius of one unit is called the unit circle.
Standard equation of circle given by
x² + y² = r²
r = radius of
∴ x² + y² = 1²
∴ x² + y² = 1
∴ ![A(\frac{\sqrt{3} }{2} ,\frac{1}{3})\\ \\and\\\\B( 1, 1)](https://tex.z-dn.net/?f=A%28%5Cfrac%7B%5Csqrt%7B3%7D%20%7D%7B2%7D%20%2C%5Cfrac%7B1%7D%7B3%7D%29%5C%5C%20%5C%5Cand%5C%5C%5C%5CB%28%201%2C%201%29)
Points are not on the unit circle as on substituting this x and y values
in the above equation we get
Left hand side ≠ Right-hand side
∴ ![A(\frac{\sqrt{3} }{2} ,\frac{1}{3})\\ \\and\\\\B( 1, 1)](https://tex.z-dn.net/?f=A%28%5Cfrac%7B%5Csqrt%7B3%7D%20%7D%7B2%7D%20%2C%5Cfrac%7B1%7D%7B3%7D%29%5C%5C%20%5C%5Cand%5C%5C%5C%5CB%28%201%2C%201%29)
could not be the points on the unit circle.

The answer would b be d 8 I think
Answer: $2105.26
Step-by-step explanation:
<u>Concept:</u>
The formula to find simple interest is I=Prt
<u>Given:</u>
t=5 year
r=4.75%
I=$500
<u>Solve:</u>
I=Prt
500=P(4.75%)(5)
100=P(4.75%)
<h2>P=$2105.26</h2>
Answer:
![\sigma=6.16](https://tex.z-dn.net/?f=%5Csigma%3D6.16)
Step-by-step explanation:
By definition, the variance V of a population is defined as:
![V = \sigma^2](https://tex.z-dn.net/?f=V%20%3D%20%5Csigma%5E2)
Where
is the standard deviation
We know that
, then we can solve the equation for the standard deviation ![\sigma](https://tex.z-dn.net/?f=%5Csigma)
![38 = \sigma^2](https://tex.z-dn.net/?f=38%20%3D%20%5Csigma%5E2)
![\sigma^2=38](https://tex.z-dn.net/?f=%5Csigma%5E2%3D38)
![\sigma=\sqrt{38}](https://tex.z-dn.net/?f=%5Csigma%3D%5Csqrt%7B38%7D)
![\sigma=6.16](https://tex.z-dn.net/?f=%5Csigma%3D6.16)
Finally the standard deviation is: ![\sigma=6.16](https://tex.z-dn.net/?f=%5Csigma%3D6.16)
