Let us write vertices of the given rectangle are PQRS.
Where Q is (c,d) and S is (a,b).
a) Now, we need to find the coordinates of P and R points.
x-coordinate for P is a and y-coordinate of P is d.
<h3>Therefore P is (a,d).</h3>On the same way, x-coordinate for R is c and y-coordinate of R is b.
<h3>Therefore R is (d,b).</h3>b) <em>Width of the rectangle is difference of y-coordinates of P and S points</em>.
<h3>Therefore, width = b - d.</h3>
Answer:
Step-by-step explanation:
Hello!
Table is attached.
1) Purple stem/short petals.
(o-e)= 220-225= -5
(o-e)²= (-5)²= 25
(o-e)²/e= 25/225= 1/9
2) Green stem/short petals
(o-e)= 210-225= -15
(o-e)²= (-15)²= 225
(o-e)²/e= 225/225= 1
3) Purple stem/ long petals
(o-e)= 231-225= 6
(o-e)²= (6)²= 36
(o-e)²/e= 36/225= 4/25
4) Green stem/ long petals
(o-e)= 239-225= 14
(o-e)²= (14)²= 196
(o-e)²/e= 196/225 (≅ 0.871)
To reach the statistic value you have to add the four values obtained in the last row:
X²= 1/9+1+4/25+196/225= 482/225≅ 2.142
I hope you have a SUPER day!
