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!

Equation; y=27x+405Step 1: Flip the equation.<span><span><span>27x</span>+405</span>=y</span>Step 2: Subtract 405 from both sides.<span><span><span><span>27x </span>+ 405 </span></span>= <span>y
<span> -405 −405</span></span></span><span><span>27x</span>=<span>y−405</span></span>Step 3: Divide everything by 27.<span><span><span><u>27x</u> </span></span>= <span><span><u>y − 405</u>
