Answer:
$190.50
Step-by-step explanation:
Expected value is the sum of each possible income multiplied by its probability.
There's a 5% chance that the vendor makes $200 and loses $190 (net gain of $10).
There's a 95% chance that the vendor makes $200 and loses $0 (net gain of $200).
So the expected value is:
Exp(RS) = $10 × 0.05 + $200 × 0.95
Exp(RS) = $190.50
2. Each side of a pentagon is the same size.
4cm x 5 = 20cm or 4cm+4cm+4cm+4cm+4cm = 20cm
3. Each side of a square is the same size.
13yd x 4 = 52yd or 13yd+13yd+13yd+13yd = 52yd
4. Add all sides together.
12m+12m+30m+30m = 84m
5. Again add all sides together.
16yd+16yd+4yd+4yd = 40yd
6. Each side of a square is the same size.
7in x 4 = 28in. or 7in+7in+7in+7in = 28in
7. Add all sides together.
2cm+2cm+3cm+3cm = 10cm
8. Each side of a rhombus is the same size. A rhombus has 4 sides.
23in x 4 = 92in or 23in+23in+23in+23in = 92in
9. A regular octagon has 8 sides and each side is the same size.
9cm x 8 = 72cm

Answer:
21.4 degrees =x
Step-by-step explanation:
We can use the law of sines to solve this problem
sin A Sin B
------------ = ----------
a b
where A is the angle and a is the opposite side
sin 42 Sin x
------------ = ----------
22 12
Using cross products
12 sin 42 = 22 sin x
Divide by 22
12/22 sin 42 = 22/22 sin x
12/22 sin 42 = sin x
Take the arcsin of each side
arcsin (12/22 sin 42) = arcsin( sin x)
arcsin (12/22 sin 42) = x
21.40637223=x
Rounding to the nearest tenth
21.4 degrees =x
