Answer:
D. 16 °F
Step-by-step explanation:
Given:
The initial temperature of the outside is 0 °F.
Decrease in the temperature in the first hour = 12 °F
Therefore, temperature after 1 hour = 0 - 12 = -12 °F
Now, decrease in the temperature in the second hour = 4 °F
Therefore, temperature after 2 hours = -12 - 4 = -16 °F
Let 'x' °F be added to the final temperature in order to bring it to 0 °F.
Therefore,
Adding 16 on both sides, we get:
Hence, we need to increase the temperature by 16 °F to attain the same initial temperature of 0 °F.
It looks like we have
and we want to find .
Since is approaching 5, we don't care about the value of
when
.
We do care about how behaves to either side of
. If
from below, then
, so that
On the other hand, if from above, then
, so that
The one-sided limits do not match, since 0 ≠ 8, so the limit does not exist.
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)

Given:
A card is selected randomly from a standard deck of 52 cards.
To find:
The probability of each outcome.
a. a king of heart
b. a queen of spades
c. an ace of flower
d. an ace of diamond
Solution:
In a standard deck of 52 cards.
Total number of cards = 52
13 cards of each suit (heart, diamond, club, spade).
13 cards are Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King.
a. We need to find the probability of getting a king of heart.
Number of king of heart = 1
b. We need to find the probability of getting a queen of spades.
Number of queen of spades = 1
c. We need to find the probability of getting an ace of flower (spades).
Number of ace of flower = 1
d. We need to find the probability of getting an ace of diamond.
Number of ace of diamond = 1
Therefore, the required probabilities for each parts are:
(a)
(b)
(c)
(d)
