lukranit [14]

Answer:

0.4

Step-by-step explanation:

If the ratio of boys to girls in a class is 2:3, then

there are 2x boys;
there are 3x girls.

If there are 18 girls in the class, then

$3x=18\\ \\x=6$

Thus, there are

$2\cdot 6=12$ boys;
$3\cdot 6=18$ girls;
$12+18=30$ students in total.

The probability of a boy being in the class is

$P=\dfrac{12}{30}=\dfrac{2}{5}=0.4$

1) A) Name of triangle: ABO

B) Exterior AngleS: EAO, BOC and AOD

C) Remote Interior Angles: For EAO, it’s ABO and AOB. For BOC, it’s BAO and ABO. For AOD, it’s BAO and ABO

2) A) Name of triangle: ABC

B) Exterior Angles:EAC

C) Remote Interior Angles: ABO and BCO

3) A) Name of triangle: DOC

B) Exterior Angles: ODH, DOA, COB, and OCG

C) Remote Interior Angles: For ODH, it’s DOC and COD. For DOA, it’s ODC and DCO. For COB, it’s ODC and DCO. For OCG, it has CDO and DOC

4) A) Name Of triangle: COB

B) Exterior Angles: AOB, DOC, and OBF

C) Remote Interior Angles: For AOB, it’s OBC and OCB. For DOC, it’s OBC and OCB. For OBF, it’s BOC and OCB
