Answer:
(x+2) (x+6)
Step-by-step explanation:
x^2+8x+12
What 2 numbers multiply together to give you 12 and add together to give you 8
2*6 = 12
2+6 = 8
(x+2) (x+6)
To find the Chebyshev's inequality, P | Xn - E(X)| <= δ/4 >= 1 - (δ^2/25)/(δ^2/16) = 1 - (16/25) = 9/25 = 0.36
The answer in this question which is the probability that the average of the physicist's measurement is within δ/4 units of the actual specific gravity is at least 0.36%
It has 8 faces but 12 vertices
1. Drawn a straight line AB =7 cm with the help of ruler.
2. With the help of compass drawn an arc from A and at the point where it cuts AB from that point made another arc drawn an arc cutting the previous arc.
3. From A drawn a straight line joining the arc and extend it to M.
4. With the help of ruler measured 5 cm and mark it as AC.
5. Joined BC and we get the required triangle.
6. From C drawn an arc and make it cut on AC and BC and from the point it cuts AC and BC drawn arc cutting each other and extend a line from point C extend a line to the point point of intersection of two arc.
7. Similarly we do for A and the point where the two line intersect denoted as O.
8. Made a perpendicular from O on AB this perpendicular will be radius and taking O as centre we draw a circle this is our incircle.
9. And AN is our locus of points equidistant from two lines AB and AC.
We need to construct a circle inscribed in triangle that is incircle it can be done by making angle bisector of two sides the point where it intersect will be incentre. The centre of required circle.
The angle bisector is the locus where points are equidistant from two sides.

Hey hey!
To figure out the congruence you have to look at the lines and ticks on both triangles.
So when it gives you one letter you know it's asking for an angle.
And when it gives you two letters you know it's a segment.
When it gives you three letters you're looking for an angle.
A)
<A = <X
<B = <Z
<C = <Y
B)
AB = XZ
AC = XY
BC = ZY
C)
This one is a little tricky, so when it gives you a three-letter angle you have to look at the 'samwitched' letter, which in this case would be A.
To answer this first you have to figure out what angle corresponds to A which would be X.
And then to answer you could say either <u>YXZ or ZXY</u> as long as the X is in the middle it's okay.
I hope this helps a bit :)
