Answer:
Average of amount of time students spend trying to find an eatery spot on campus.
The sample would be a pool of 100 students to survey from.
Population would be all the students attending Harvard university.
Statistic would be the average amount of time spend looking for eatery spot in campus.
The parameter would be the mean used to find the average amount of time spent looking for eatery spot in campus.
It was a convenient sample.
Step-by-step explanation:
A population is the entire pool from which a statistical sample is drawn. In this case our population is the entire students that attend Harvard University.
A sample is usually drawn from a population. In this case, the 100 students that were drawn from the population is the sample.
The sample was a convenient sample as the sample can be easily drawn from the population population, it doesn't depend on any probability.
X=40 the right angle is 90 degrees and 90-10 = 80, 80 = 2x, so x = 40
It is more convinient to use substitution
5(10)-y=54
50-y=54
-y=54-50
-y=4
y=4/-1
y=-4
hope its help you
The elevation of the city is between -15 and -16
Step-by-step explanation:
The Earth surface is highly uneven. Hence for relative comparison, scientist over the world assume the sea level as the reference point (meaning that sea level is considered to be at 0 elevation and all other elevations and depths are calculated regarding the sea level)
As given in the question city’s elevation is 15.3 feet below sea level. Hence the city is below the sea level by 15.3 feet
On the mathematical scale below 0 would mean the number system is negative. Similarly, the city is located at -15.3 feet when compared to sea level which is at 0 feet.
Hence -15.3 would lie between -15 and -16
