All the angles in a triangle should add up to 180. Therefore 180-125 is 55 meaning the third angle is 55 degrees

You take the three zeros and put them back with the x s 

(x-6)(x+5)(x-2)  they are reversed when you put them back in 

multiply the first two and get x^2+5x -6x-30(x-2) 
simplify to x^2-x-30(x-2)

Multiply it out again and get x^3-x^2-30x-2x^2+2x+60
finally simplify and get x^3-3x^2-28x+60 

So the answer is the first one

Answer:

d) 6.750

<em>The chi - square value = 6.750</em>

Step-by-step explanation:

Given data

Starting Position              1           2            3           4            5              6  

Number of Wins (O)       33        44            32         36         45           50

<u><em>Step(i) :</em></u>-

mean = \frac{33+44+32+36+45+50}{6} = \frac{240}{6} =40

Expected frequency = 40

Number of Wins (O)      :     33        44            32         36         45           50

Expected frequency(E)   :   40         40           40         40          40          40

(O - E )                              :    -7          4              -8           -4           5            10

(O-E)²                               :     49         16           64          16          25          100

\frac{(O-E)^2}{E}                              :      1.225    0.4       1.6         0.4         0.625     2.5  

<u><em>Step(ii):-</em></u>

<u><em>The χ² test</em></u>

<em>      χ²   =    ∑   </em>\frac{(O-E)^2}{E}<em></em>

<em>   χ²  =  1.225 + 0.4 + 1.6 + 0.4 +0.625 +2.5 = 6.75</em>

<em>The chi - square value = 6.750</em>

<u><em>Final answer</em></u><em>:-</em>

<em>The chi - square value = 6.750</em>

<u><em>                  </em></u>

<u><em></em></u>
