Your friend claims that because each midsegment is half as long as the corresponding side of the triangle, the perimeter of the
lora16 [44]
Answer:
The claim is correct

Explanation:
Assume the given triangle ABC
perimeter of triangle ABC = AB + BC + CA ............> I

Now, we have:
D is the midpoint of AB, this means that:
AD = DB = (1/2) AB ..........> 1
E is the midpoint of AC, this means that:
AE = EC = (1/2) AC ...........> 2
DE is the midsegment in triangle ABC, this means that:
DE = (1/2) BC ...........> 3
perimeter of triangle ADE = AD + DE + EA
Substitute in this equation with the corresponding lengths in 1,2 and 3:
perimeter of triangle ADE = (1/2) AB + (1/2) BC = (1/2) AC
perimeter of triangle ADE = (1/2)(AB+BC+AC) .........> II

From I and II, we can prove that:
perimeter of triangle ADE = (1/2) perimeter of triangle ABC
Which means that:
perimeter of midsegment triangle is half the perimeter of the original triangle.

Hope this helps :)

The probability of one event given the known outcome of a (possibly) related event is known as _____ probability.
Deffense [45]

The probability of one event given the known outcome of a (possibly) related event is known as unconditional probability.

Given an incomplete sentence related to probability.

We are required to fill the sentence by the appropriate terms given as options.

Probability is basically the chance of happening an event among all the events possible.  It cannot be negative.

Marginal probability is basically the probability of an event irrespective of the outcome of another variable.

Conditional probability is basically probability of one event occuring in the presence of a second event.

Unconditional probability is basically the chance that a single outcome results among several possible outcomes.

Joint probability is a basically a statistical measure that calculates the likelihood of two events occurring together and at the same point in time.

From the above definitions and the sentence given we can say that the appropriate term is unconditional.

Hence the appropriate term which can be filled in the sentence is unconditional.
