X=2
To check it you plug in 2 for x. Which then gives you:
3+(2-14)=-15+6 which then gives you:
3+-12=-15+6 which the gives you:
-9=-9
(x`-b/2a)-D/4a
(x`-7)+576
answer! (7;-576)
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!
