(2/3)*x - (1/2)*x = 3
*make common denominators
(2*2)/(2*3)*x - (3*1)/(3*2)*x = 3
(4/6)*x - (3/6)*x = 3
(1/6)*x = 3
x = 3*(6/1)
x = 3*6
x = 18 gallons of gas

Answer:
Step-by-step explanation:
Information given
represent the sample mean for the content of active ingredient
represent the sample standard deviation for the sample
sample size
represent the value that we want to test
t would represent the statistic
represent the p value for the test
System of hypothesis
We need to conduct a hypothesis in order to check if the true mean for the active agent is at least 20 mg, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic would be:
(1)
Now we can calculate the statistic:
P value
The degrees of freedom are calculated like this:
Since is a one left tailed test the p value would be:
Answer:
D. There are no constitutional requirements for becoming a federal judge.
Step-by-step explanation:
This equation in numbers:
(-8x)^6 • (4x)^2
(262144•x^6) • (16x^2)
4,194,304x^8
