In a completely randomized design, 12 experimental units were used for the first treatment, 15 for the second treatment, and 20 for the third treatment. complete the following analysis of variance (to 2 decimals, if necessary). round p-value to four decimal places. if your answer is zero enter "0".source of variation sum of squares degrees of freedom mean square f p-valuetreatments 1,3002,000a .05 level of significance, is there a significant difference between the treatments? the p-value is ? what is your conclusion?

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3
