23.125$
Step-by-step explanation:
you have to divide the total amount of money by the total amount of people 92.50$/4=23.125$
Answer:
We see that the p value is lower than the significance level given of 0.01 so then we can conclude that the true mean for the nicotine content is significantly higher than 40 mg
Step-by-step explanation:
Information provided
represent the average nicotine content
represent the sample standard deviation
sample size
represent the value to check
represent the significance level for the hypothesis test.
t would represent the statistic
represent the p value for the test
System of hypothesis
We want to verify if the nicotine content of the cigarettes exceeds 40 mg , the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
The statistic for this case would be:
(1)
And replcing we got:
The degrees of freedom are:
The p value would be:
We see that the p value is lower than the significance level given of 0.01 so then we can conclude that the true mean for the nicotine content is significantly higher than 40 mg
Answer:
B
Step-by-step explanation:
Pythagorean theorem (applicable on right triangles only) says:

- Where
and
are the two legs of the triangle and
is the length of the hypotenuse [THE LONGEST SIDE].
<u>We can square each leg on the triangle and take the sum, if that is equal to the square of the longest side, we have a right triangle. Let's check for all of these.</u>
A.


They're not right triangle.
B.


This is a right triangle.
C.


They're not right triangle.
D.


They're not right triangle.
Only B is the right triangle.
1 gallon= 4 quarts so if you were to have 1/2 a gallon and 2 quarts, you would have an equal amount so the containers hold the same amount
