Based on the given conditional statement, the biconditional statement would be The sum of two angles is 180° if and only if the angles are supplementary.
<h3>What is the biconditional statement?</h3>
A biconditional statement takes a conditional statement and restates it while also stating its converse.
To do so, it will often use the words, "if and only if" to emphasize the condition required.
The biconditional statement here is therefore:
" The sum of two angles is 180° if and only if the angles are supplementary."

Answer:
11/18
Step-by-step explanation:
The desired probability is the sum of ...
... (probability of choosing a coin) × (p(heads) on that coin)
Since the coins are chosen at random, we assume the probability of choosing a given coin is 1/3. Then ...
... p(heads) = (1/3)·(1/2) + (1/3)·1 + (1/3)·(1/3) = 1/6 + 1/3 + 1/9 = (3 +6 + 2)/18
... p(heads) = 11/18
2007 would be 0 years since 2007
y=25000+700(0)
y=25000
