If the probability that Stock A will increase in value during the next month is 0.54, and the probability that Stock B will incr
1 answer:
Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
Probability that Stock A will increase in value during the next month = 0.54
Probability that Stock B will increase in value during the next month = 0.68
P(A) = 0.54
P(B) = 0.68
so, P(A)+P(B) = 0.54+0.68=1.22
Probability that neither of these two events will occur is given by
Hence, Option 'A' is correct.

Answer:
The image of the point (1, -2) under a dilation of 3 is (3, -6).
Step-by-step explanation:
Correct statement is:
<em>What are the coordinates of the image of the point (1, -2) under a dilation of 3 with the origin.</em>
From Linear Algebra we get that dilation of a point with respect to another point is represented by:
(Eq. 1)
Where:
- Reference point with respect to origin, dimensionless.
- Original point with respect to origin, dimensionless.
- Dilation factor, dimensionless.
If we know that ,
and
, then the coordinates of the image of the original point is:
The image of the point (1, -2) under a dilation of 3 is (3, -6).
