Answer:
80
Step-by-step explanation:
180-(60+40)=180-60-40=180-100=80
Answer:
We have:
x < 4 AND x > a.
if a = 4 and we use an "or" instead of the "and" we have:
x < 4 or x > 4.
This is:
"x is larger than 4 or smaller than 4."
Then the solution of this is all the real numbers except the value x = 4.
The set of solutions can be written as:
{xI x ∈ R \ [4]}
Where this reads:
"x belongs to the set of the reals minus the number 4".
Or we also could write it as:
x ∈ (-∞, 4) ∪ (4, ∞)
Where we have two open ends in the "4" side, so the value x = 4 does not belong to that set.
That point would be : (2.5,5)
I think the answer is 60/t = 5
Median is generally good if you have outliers (data points that are very far off from the majority of the points).
Mean can be used otherwise.
