For this case we have that the temperature drops steadily at a speed of , that is, every hour drops 0.8 degrees. So, we can propose a rule of three:
1 hour ----------> 0.8 degrees
x ------------------> 4.4 degrees
Where the variable "x" represents the number of hours that must pass for the temperature to decrease by 4.4 degrees.
Thus, for the temperature to decrease by 4.4 degrees, 5.5 hours must pass.
<u>Answer:</u>
5.5 hours

Answer:
0.1505 = 15.05% probability that the hockey team wins 6 games in November
Step-by-step explanation:
For each game, there are only two possible outcomes. Either the team wins, or it does not. The probability of winning a game is independent of winning other games. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
The probability that a certain hockey team will win any given game is 0.3723
So
12 games in November
So
What is the probability that the hockey team wins 6 games in November?
This is
0.1505 = 15.05% probability that the hockey team wins 6 games in November
