The answer in this question is A, D and E, we might conclude if a random sample of 36 time interval between eruption has a mean longer that 104 minutes, I can conclude that the population means may be greater than 91 and the probability mean must be more that 91, since the probability is low and also the population mean is 91, and this is an example of a typical sampling result.
Answer:
y = 120°
Step-by-step explanation:
angles in a triangle add up to 180 degrees
180 - (87 +33) = 60
x = 60 degrees
angles on a straight line add up to 180 degrees
180 - 60 = 120
y = 120
Given: The time taken to do each activity from Colin's house to his hotel in given.
- he drove to the airport for 45 minutes
- he waited at the airport for the flight to depart for 90 minutes
- his fight duration was 70 minutes
- upon landing, he gathered his luggage for 20 minutes
- he drove to the hotel for 35 minutes
To Find: what is true of any expression that represents the total time Collin spent traveling from his house to the hotel
Solution: Any expression will involve the sum of all the durations of his various activities i.e., 260 minutes or 4 hours and 20 minutes.
Explanation:
As each of the activities described is an independent activity that does not overlap, we can easily sum up the durations of each to find the total time Collin took from his house to the hotel.
We add it as follows :
he drove to the airport for 45 minutes + he waited at the airport for the flight to depart for 90 minutes + his fight duration was 70 minutes + upon landing, he gathered his luggage for 20 minutes + he drove to the hotel for 35 minutes.
So, 45+90+70+20+35 = 260 minutes
which means it took a total of 260 minutes or 4 hours and 20 minutes from Collin's house to his hotel.
