nlexa [21]

Answer:

2,300

Explanation:

This is given as:

$\begin{gathered} 25\text{ combination 3 represented as:} \\ ^nC_r=\frac{n!}{r!(n-r)!} \\ n=25 \\ r=3 \\ ^{25}C_3=\frac{25!}{3!(25-3)!} \\ ^{25}C_3=\frac{25\times24\times23\times22!}{3!\times22!} \\ ^{25}C_3=\frac{25\times24\times23}{3\times2\times1} \\ ^{25}C_3=2300 \end{gathered}$

Therefore, there are 2,300 ways that 3 persons can be selected from 25 people

Mashcka [7]

Theorem: If two chords intersect within a circle, then the product of the lengths of the segments (parts) of one chord is equal to the product of the lengths of the segments of the other chord.

In your case this theorem sounds as

$AM\cdot MB=CM\cdot MD.$

If AM=7, MB=6, CM=8, then

$7\cdot 6=8\cdot MD,\\ \\MD=\dfrac{7\cdot 6}{8}=\dfrac{21}{4}=5.25.$

Note that CD=CM+MD=8+5.25=13.25.

Answer: correct choice is C
