Answer:
51 degrees
Step-by-step explanation:
All right angles are 90 degrees and all triangles interior angles add up to 180.
39+90=129
180-129=51
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:
Answer is D. Mean decreases and median stays the same
Step-by-step explanation:
First put the amounts in this format
$31, $39, $50, $50, $70, $82
Median (middle of all numbers) is 50
Mean (add all numbers then divide by how many amounts there) is 53.6
Now incorporate the 7th week
$23, $31, $39, $50, $50, $70, $82
Median is still 50
Mean is now 49.28
It could be 10 which would make the triangle a right triangle, since the values follow the Pythagorean theorem (a^2+b^2=c^2)
