10.5 in the form of a/b = 105/10 = 21/2
The parts that are missing in the proof are:
It is given
∠2 ≅ ∠3
converse alternate exterior angles theorem
<h3>What is the Converse of Alternate Exterior Angles Theorem?</h3>
The theorem states that, if two exterior alternate angles are congruent, then the lines cut by the transversal are parallel.
∠1 ≅ ∠3 and l║m because we are: given
By the transitive property,
∠2 and ∠3 are alternate interior angles, therefore, they are congruent to each other by the alternate interior angles theorem.
Based on the converse alternate exterior angles theorem, lines p and q are proven to be parallel.
Therefore, the missing parts pf the paragraph proof are:
- It is given
- ∠2 ≅ ∠3
- converse alternate exterior angles theorem

Answer:
4(3) - 7 = 4(3 - 1) - 3
12 - 7 = 4(2) - 3
5 = 8 - 3
= 5
They are equivalent because when they are both simplified they have the same answer 5
Probability of an event is the measure of its chance of occurrence. The event out of the listed events whose probability is 0.2957 is given by : Option C: 
<h3>How to get the z scores?</h3>
If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z-score.
If we have

(X is following normal distribution with mean
and standard deviation
)
then it can be converted to standard normal distribution as

(Know the fact that in continuous distribution, probability of a single point is 0, so we can write

Also, know that if we look for Z = z in z tables, the p-value we get is

Using the z-table, we get the needed probabilities as:
Case 1:

Case 2:

Case 3:

Case 4:

Thus, the event out of the listed events whose probability is 0.2957 is given by : Option C:
