Look at the figure shown below:
boyakko [2]

These are the steps, with their explanations and conclusions:


1) Draw two triangles: ΔRSP and ΔQSP.


2) Since PS is perpendicular to the segment RQ, ∠ RSP and ∠ QSP are equal to 90° (congruent).


3) Since S is the midpoint of the segment RQ, the two segments RS and SQ are congruent.


4) The segment SP is common to both ΔRSP and Δ QSP.


5) You have shown that the two triangles have two pair of equal sides and their angles included also equal, which is the postulate SAS: triangles are congruent if any pair of corresponding sides and their included angles are equal in both triangles.


Then, now you conclude that, since the two triangles are congruent, every pair of corresponding sides are congruent, and so the segments RP and PQ are congruent, which means that the distance from P to R is the same distance from P to Q, i.e. P is equidistant from points R and Q

Jane is taking two courses. The probability she passes the first course is 0.7. The probability she passes the second course is
-Dominant- [34]

Answer: p = 0.56

Step-by-step explanation: from the question, probability she passed the first course = 0.7

Probability she passed the second course = 0.8

Probability she passes both courses means probability she passes the first course "and" probability she passes the second course.

Probability she pass both courses = 0.7 * 0.8 = 0.56

Note that "and" in probability means multiplication.
