The number -5 should be added to -21 to get -26
Answer:
P=0.17
Step-by-step explanation:
If A and B are dependent events, then we have a Rule of Addition:
Let A represent event that customer at Mega Hit is subscribed to premium movie channels while B represent event that customer at Mega Hit owns a DVD, so, we get the following:
We need to find 
or probability that a randomly selected Mega Hit customer both owns a DVD and subscribes to a premium movie channels.
Using Rule of Addition, we get:
So, the required probability is 0.17.
Answer:
Will you give me the numbers so I can give you the answer?
Step-by-step explanation:
To put this into simpler terms, well simplier for me anyways, Emma is dividing 9 inches of paper into 2/5, or .4, inches of paper.
That being said, we now just need to divide 9 by 2/5 or .4
We get 22.5
So Emma will be able to make 22 strips since we can't have half a strip. (Well, we could, but it would be small than what we need)
Any questions?
Answer:
14.5, 13, 11.5
Step-by-step explanation:
The general term (an) of an arithmetic sequence with first term a1 and common difference d is ...
an = a1 + d(n-1)
Then the 8th term is ...
a8 = a1 + d(8-1)
and the 12th term is ...
a12 = a1 + d(12-1)
So, the difference between these terms is ...
a12 -a8 = (a1 +11d) -(a1 +7d) = 4d
= (-2-4) = -6 . . . . . substituting values for a12 and a8
Then the common difference is
... d = -6/4 = -3/2
Using this, we can find a1 from a8.
4 = a1 +7·(-3/2) = a1 - 10.5
14.5 = a1 . . . . . . . add 10.5 to both sides of the equation
This is the first term. The second is this value with the common difference added:
14.5 + (-1.5) = 13
The third term is this with the common difference added:
13 + (-1.5) = 11.5
In summary, the first three terms are ...
14.5, 13, 11.5
