7,000,000,000 + 0 + 50,000,000 + 1,000,000 + 0 + 0 + 4,000 + 200 + 60 + 4
I’m not sure if you’re supposed to put the commas in it
Simplifying
2x + 3y = 1
Solving
2x + 3y = 1
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3y' to each side of the equation.
2x + 3y + -3y = 1 + -3y
Combine like terms: 3y + -3y = 0
2x + 0 = 1 + -3y
2x = 1 + -3y
Divide each side by '2'.
x = 0.5 + -1.5y
Simplifying
x = 0.5 + -1.5y
Answer:
Step-by-step explanation:
Information given
represent the sample mean of amount of liquid
represent the standard deviation
sample size
represent the value that we want to check
t would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
System of hypothesis
We want to verify if the true mean for the amount of liquid is lower than 12 ounces, and the hypothesis are given by:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing we got:
