4x^2(2x+1)-9(2x+1)=0
(4x^2-9)(2x+1)=0
(2x-3)(2x+3)(2x+1)=0
Answer:
2x
Step-by-step explanation:
Volume of a cylinder is:
V = πr²h
If V = 4πx³ and h = x, then:
4πx³ = πr²x
4x² = r²
r = 2x

Answer: The P-Value is .039337. The result is not significant at p < .01.
Step-by-step explanation:
In the following Chi square table attached, the value is of df=8 and chi square statistic value of 16.22 is found to be between (15.507, X²₀.₀₅) and ( 17.353, X²₀.₀₂₅).
Using the table for critical value calculation:-
Df=8 Critical value for 1%= 1.646, and we calculated our value of 17.353.
We can reject is on the basis of X²calculated > X²Critical.
The outcome doesn't falls to be in 1% of the distribution.
or
We can reject it on basis that the outcome between X²₀.₀₅ and X²₀.₀₂₅ whereas the required level of upper distribution is X²₀.₀₁
