Step-by-step explanation: hope this help:)
Answer:
![\boxed{\left(x+i\sqrt{\frac{2}{3}}i \right)\left(x-i\sqrt{\frac{2}{3}}i \right)}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cleft%28x%2Bi%5Csqrt%7B%5Cfrac%7B2%7D%7B3%7D%7Di%20%5Cright%29%5Cleft%28x-i%5Csqrt%7B%5Cfrac%7B2%7D%7B3%7D%7Di%20%5Cright%29%7D)
Step-by-step explanation:
Setting the expression equal to zero to find the roots,
![3x^2 +2=0\\\\3x^2 =-2\\\\x^2 =-\frac{2}{3}\\\\x=\pm i\sqrt{\frac{2}{3}}](https://tex.z-dn.net/?f=3x%5E2%20%2B2%3D0%5C%5C%5C%5C3x%5E2%20%3D-2%5C%5C%5C%5Cx%5E2%20%3D-%5Cfrac%7B2%7D%7B3%7D%5C%5C%5C%5Cx%3D%5Cpm%20i%5Csqrt%7B%5Cfrac%7B2%7D%7B3%7D%7D)
This means that
![3x^2 +2=\boxed{\left(x+i\sqrt{\frac{2}{3}}i \right)\left(x-i\sqrt{\frac{2}{3}}i \right)}](https://tex.z-dn.net/?f=3x%5E2%20%2B2%3D%5Cboxed%7B%5Cleft%28x%2Bi%5Csqrt%7B%5Cfrac%7B2%7D%7B3%7D%7Di%20%5Cright%29%5Cleft%28x-i%5Csqrt%7B%5Cfrac%7B2%7D%7B3%7D%7Di%20%5Cright%29%7D)
Answer: The area is 15 square units
Step-by-step explanation: It is helpful to sketch the coordinates on a graph to get an idea of what the triangle looks like so you can see which side will be the base, and where to get the height. You will see that AB is the hypotenuse, it is a right triangle, so AC can be the base and BC is the height.
Use the differences in x-values of points C & A to get the length of the base: 2-(-3) is 5
Use the differences in y-values of points B & C to get the height:
4-(-2) = 6
Area = bh/2
A = 5×6/2 = 30/2
A = 15 square unts
The answer is 7. 8P=4 3q=21. you add those and get 25 then subtract 18 and get 7
A 99% confidence interval will be wider compared to a 95% confidence interval. This is because while you don't know what the true value of mu is, you are more confident that the parameter is in the interval.
In essence, you are casting a wider net which leads to the higher level of confidence. Imagine if there was a 100 mile stretch of straight land, and somewhere on this line was a special rock that you are looking for. You would be 100% confident if you said "the rock is somewhere on that piece of land", and less confident the more you shrunk the interval.
