Answer:
$3,400
Step-by-step explanation:
The expected value is the sum of products of the value and its probability:
E = 2000(0.1) +3500(0.8) +4000(0.1) = 200 +2800 +400 = 3400
The expected value of the investment is $3,400.
all triangles are similar but B and D may be the answer
The Pythagorean theorem is sqrt(a^2 + b^ 2) = c, so:
sqrt(22^2 + 8^2) = c
sqrt(548) = c
23.41 = c
x=y+3
you just swap variables.
