Mean = Sum / number
Mean = (8 + 6 +4) / 3
= 18 / 3
= 6
Mean = 6
You know that D is 35° cause of the angle next to F. and <E=180-(120+35) so E is 25°
Answer:





The plot is on the figure attached. And we can see that the residuals shows a curved pattern so then the best conclusion for this case would be:
Yes, the points are in a curved pattern.
Step-by-step explanation:
The correct formula for the residuals is given by:

Who represent the observed value minus the predicted. We can find the individual residuals and we got:





The plot is on the figure attached. And we can see that the residuals shows a curved pattern so then the best conclusion for this case would be:
Yes, the points are in a curved pattern.
Answer:each album costs $7 and you buy x of them
cost of albums = 7x
each movie costs $8 and you have you have y of them
cost of movies = 8y
total cost is has to be less than $47
---> 7x + 8y < 47
sketch the graph of 7x + 8y = 47 , a straight line, and shade in the region below that line. Of course you would stay in the first quadrant, (x > 0, and y >0 , since you can't have negative number of movies and albums)
Since you can't buy partial albums and movies, both x and y have to be whole numbers.
So for solutions you would consider only ordered pairs that have whole numbers as their components.
e.g. (2, 2) or (1,5)
Step-by-step explanation: Hope this helps :)
