Answer: Hence, Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Probability of successful outcome = 0.7
Probability of unsuccessful outcome = 0.3
Amount he get for successful outcome = $900
Amount he lost for unsuccessful outcome = -$1800
We need to find the expected value of return when there is successful outcome:
P(Success)× Amount for successful
Hence, Option 'D' is correct.
Answer:
The triangles are not similar
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
<em>Triangle X.Y.Z</em>
---> angle X and angle Y are complementary angles
<em>Triangle H.G.J</em>
---> angle H and angle J are complementary angles
so
X.Y.Z is a triangle
H.G.J is a triangle
The measure of its corresponding angles are not congruent
therefore
The triangles are not similar
