Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ - 5, 6 ] , then
f(b) = f(6) = 6² - 2(6) - 5 = 36 - 12 - 5 = 19
f(a) = f(- 5) = (- 5)² - 2(- 5) - 5 = 25 + 10 - 5 = 30
Then
average rate of change = =
=
= - 1
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!
