Your answer should be 2x+5 if you are supposed to simply the expression
A scale factor of 2 means the dimensions are multiplied by 2.
15 x 2 = 30
8 x 2 = 16
The answer is true. A conditional probability is a measure
of the probability of an event given that (by assumption, presumption,
assertion or evidence) another event has occurred. If the event of interest is
A and the event B is known or assumed to have occurred, "the conditional
probability of A given B", or "the probability of A in the condition
B", is usually written as P (A|B). The conditional probability of A given
B is well-defined as the quotient of the probability of the joint of events A
and B, and the probability of B.
