Find the value of y
------------------------------------------------------------------------
y - 18 = 14
+ 18 + 18
y = 32
------------------------------------------------------------------------
substitute y = 32 into 2 (y + 9)
------------------------------------------------------------------------
2( y + 9 ) = 2 ( 32 + 9 )
2 (y + 9 ) = 2 (41)
2 ( y + 9 ) = 82
------------------------------------
Answer: 82

Ok.
Convert 3/4 to 6/8.

There is your answer. 3/8.
M not sure if right but strong negative?
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:
