C
Step-by-step explanation:
Median of triangle: It is a line segment joining a vertex to the midpoint of the opposite side.
Consider ΔABC, point F id the midpoint of line segment AB and E is the midpoint of luine segment AC.
Draw line segments FC and BE(medians of triangle). G is the point where line segment FC and BE meet. Now, Join AG.
Let H be the point outside the ΔABC and AG passs through the point H such that AG intersects BC at D. BH and HC are dashed lines.
We need to show that D is the midpoint of BC. The correct logical order for proof will be:
III. GC is parallel to line segment BH and line segment BG is parallel to line segment HC.
IV. Line segment FG is parallel to line segment BH and line segment GE is parallel to line segment HC.
I. BGCH is a parallelogram as opposite sides are parallel (from III.)
II. Since, diagnols of a parallelogram bisect each other. Henc, we get BD=DC.
Therefore, D is mid pont of BC.
It implies that AD is also a median.
Hence, all the three medians that are: BE,FC and AD passes through a common vertex G.
Answer:
The movie theater is 3 miles away from the the ice cream parlor.
Step-by-step explanation:
The position of Becky's school (S) and the movie theater (M)and the ice cream parlor (I) make a right triangle.
Hence, Δ SMI is a right triangle with ∠ M is the right angle i.e. 90°.
Now, given length of segment SM is 4 miles and the hypotenuse i.e. line segment SI = 5 miles.
Hence, applying Pythagoras Theorem,
SI² = SM² + MI²
⇒ 5² = 4² + MI²
⇒ MI = 3 miles.
Therefore, the movie theater is 3 miles away from the ice cream parlor. (Answer)

Answer:
2050
Step-by-step explanation:
<u>Year 2010</u>
The number of people over 65 years of age =32 million
Total population = 307 million.
P(meeting a person over 65 at random in 2010)

<u>Year 2050</u>
The number of people over 65 years of age =88 million
Total population = 434 million.
P(meeting a person over 65 at random in 2050)

Conclusion: Since 0.2028 is greater than 0.1042, the chances of meeting a person over 65 at random will be greater in 2050
