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:
She would get £2.50
4 times 2 is 8
2 times 3 is 6
0.7 times 5 is 3.5
Add them together
Minus it from 20
It equals £2.50

so 78/190=.410526=41.0526%

Answer:
ZURW and ZWRS
Step-by-step explanation:
You have to check what lines intersect.
If the temperature is the same in Farenheit and Celsius, the variable F is equal to the variable C in the equation. Thus, you'll just need to replace one or both variables in the original equation and solve for the single variable. I'll just use x as the variable here:
F = 1.8C + 32
x = 1.8x + 32
subtract x from both sides
0 = 0.8x + 32
subtract 32 from both sides
-32 = 0.8x
divide both sides by 0.8
-40 = x
So, since we know x = -40 degrees, we also know that F = -40° and C = -40° too.
