I'm pretty sure its B but I would double check before you put the answer in :)
1. A debit signifies something owed. So, that means the answer is negative.
-$40
2. A deposit means you are gaining money. So, the answer is positive.
+$225
3. Above sea level signifies to us it is above zero. So, the answer is positive.
+14000 feet
(Keep in mind, whenever they say above, it is always positive.)
4. The temperature increased, meaning that it is positive.
+40°F
5. Withdrawl implies losing money. So, the answer is negative.
-$225
6. Below sea level implies it is below zero. So, the answer is negative.
-14000 feet
Answer:
(a)
The probability that you stop at the fifth flip would be

(b)
The expected numbers of flips needed would be

Therefore, suppose that
, then the expected number of flips needed would be 1/0.5 = 2.
Step-by-step explanation:
(a)
Case 1
Imagine that you throw your coin and you get only heads, then you would stop when you get the first tail. So the probability that you stop at the fifth flip would be

Case 2
Imagine that you throw your coin and you get only tails, then you would stop when you get the first head. So the probability that you stop at the fifth flip would be

Therefore the probability that you stop at the fifth flip would be

(b)
The expected numbers of flips needed would be

Therefore, suppose that
, then the expected number of flips needed would be 1/0.5 = 2.

From the given the option moved left 1 unit; reflected across the x axis is the correct.
what is function?
A function from a set X to a set Y in mathematics assigns each element of X exactly one element of Y. The set X is known as the function's domain, and the set Y is known as the function's codomain.
We have to describe the position of the function
relative to the basic function
.
Let the parent function is
.
After shifting one unit right it becomes,
.
After reflection in x axis it becomes,
.
Hence, from the given the option moved left 1 unit; reflected across the x axis is the correct.
