Answer:
Sarah is incorrect.
Step-by-step explanation:
By plugging 10 in as 'x' to the equation, we get y=21+(2*10). 2 x 10 is 20, and 20 + 21 is <em>not</em> 42 - it's 41. So, Sarah is incorrect.

Answer: 54%
Step-by-step explanation:
In probability and logic theory, two events are said to be mutually exclusive or disjoint when both events cannot occur or happen at the same time.
A clear example of mutually exclusive event is the set of outcomes of a single toss of a coin which can either result in heads or tails, but can not be both.
P(S) = 30%, and P(T) = 24%
P(S or T) = P(S) or P(T) = 30% + 24%
= 54%
